Why We Use Pcc In Construction
The objective of plain cement concrete alias PCC is to arrange a firm impermeable bed to RCC in the foundation where the soil is soft and flexible. It is mostly applied over brick flat soling or devoid of brick flat soling. It is also known as Cement Concrete (CC) or Blinding Concrete.

  • When, any reinforcement is not used inside the concrete, it is defined as the plain cement concrete.
  • It’s just a blend of concrete ingredients.
  • Characteristics of Plain Cement Concrete – Given below, some vital characteristics of plain cement concrete: • Compressive strength: 200 to 500 kilogram/square centimeter • Tensile strength: 50 to 100 kilogram/square centimeter • Density: 2200 to 2500 kilogram/cubic meter • Stability: Outstanding Applications of Plain Cement Concrete: PCC is mostly found in footings, grade slabs, and concrete roads.

When the underlying soil is weak and flexible, brick flat soling is provided under PCC. To form PCC, the following materials are utilized :- Cement: Normally, the Portland cement is utilized as bonding material in PCC. Fine Aggregate: Sand is employed as fine aggregate.

  1. The fineness modulus (FM) of sand should remain 1.2 to 1.5.
  2. FM stands for an index number that demonstrates the mean size of particles in sand.
  3. It is measured by carrying out sieve analysis.
  4. Coarse Aggregate: Usually, the brick chips are utilized for developing PCC.
  5. It is also possible to utilize stone chips in these conditions.

The size of the coarse aggregate remains 20mm downgrade. Water: Pure drinkable water should be provided in PCC. How to build up PPC? With the following methods, plain cement concrete is formed. The following tools are utilized for the production of PCC • Wooden or Steel rammer • Mixture machine (if any) The Thickness of PCC: The thickness of PCC is normally 50mm over Brick Flat Soling (BFS).

  1. If you don’t use BFS below PCC then the thickness should be 75¬mm.
  2. When the PCC is used in car parking area then the thickness should be 75mmover BFS.
  3. Ration of materials in PCC: The ratio of cement, sand and brick chips in foundation or basement should be 1:3:6.
  4. But, if it is applied in the car parking area, the ratio will be changed to 1:2:4.

The production method for PCC: If ready-mix concrete is applied, this step should be omitted. If PCC is produced through mixture machine then click ” How to mix concrete by mixture machine “. If the concrete is mixed manually, get help by clicking on this link ” how to mix concrete by hand “.

  1. Placing and Compaction of PCC: • Ensure that brick soling/sand bed level is perfect for PCC.
  2. Create formwork for PCC with wooden planks according to stipulated dimensions.
  3. There should be no dust and foreign materials in concreting area.
  4. The bed of PCC should be covered with polythene.
  5. Create level pillars of fresh concrete in the area at proper spacing but not in excess of 2m c/c both ways.

• Set the concrete softly from one side. Apply the mixed concrete within 45 minutes once the water is added. • For compaction and finishing of PCC, wooden rammer should be used. • The surface of PCC should be rough to combine future work prior to solidification of the concrete.

Why is RCC preferred over PCC?

PCC is weak in tension loading while strong in compression loading. RCC is strong in both.

What are the types of PCC?

PCC Grades – Based on the load-carrying capacity different PCC grades are used such as M5, M7.5, M10, and M15. Where M stands for Mix while the number represents the compressive strength of particular grade testing after 28 days curing, a Detailed tabular is provided below. Why We Use Pcc In Construction Most commonly M15 grade is used as its compressive strength remains in between ordinary and standard concrete.

Which grade is used for PCC?

The Grade of the PCC used is M15 grade. IN M15 Grade, The mix ratio is 1:2:4. (1 cement,2 sand, 4 aggregates). Applications: M15 grade plain concrete cement is used for levelling courses,bedding for footing, beams and columns e.tc.

Which cement is best for PCC?

Both OPC and PPC cements are good for construction of concrete slab. OPC is the most commonly used cement in industrial and large construction, PPC is most commonly used for small residential constructions.

What is the size of PCC?

Coarse Aggregate: – The size of the aggregate used for PCC varies from 10-12 mm to 40 mm depending on where they are to be used. If the size of the aggregate is more, it results in the reduction of cement consumption. Coarse aggregate shall be clean and free from elongated, flaky or laminated pieces.

It should be free from adhering coat, clay lump, coal residue, clinkers, slag, alkali, mica, organic matter or other substances Coarse aggregate shall be of hard broken stone of granite or similar stone, which is free from dust, dirt and other foreign matters. The smaller size of the stone is 6.3 mm.

All the course material should be retained in a 6.3 mm square mesh and should be well graded such that the void does not exceed 42%.

User Guidelines for Waste and Byproduct Materials in Pavement Construction


INTRODUCTION Portland cement concrete (PCC) pavements (or rigid pavements) consist of a PCC slab that is usually supported by a granular or stabilized base, and a subbase. In some cases the PCC slab may be overlaid with a layer of asphalt concrete. Portland cement concrete is produced at a central plant and transported to the job site in transit mixers or batched into truck mixers directly and then mixed at the project site.

In either case, the PCC is then dumped, spread, leveled, and consolidated, generally using concrete slip-form paving equipment. MATERIALS Basic components of PCC include coarse aggregate (crushed stone or gravel), fine aggregate (usually natural sand), Portland cement, and water. The aggregate functions as a filler material, which is bound together by hardened Portland cement paste formed by chemical reactions (hydration) between the Portland cement and water.

In addition to these basic components, supplementary cementitious materials and chemical admixtures are often used to enhance or modify properties of the fresh or hardened concrete. Concrete Aggregate The coarse and fine aggregates used in PCC comprise about 80 to 85 percent of the mix by mass (60 to 75 percent of the mix by volume).

  1. Proper aggregate grading, strength, durability, toughness, shape, and chemical properties are needed for concrete mixture strength and performance.
  2. Portland Cement and Supplementary Cementitious Materials Portland cements are hydraulic cements that set and harden by reacting with water, through hydration, to form a stonelike mass.

Portland cement typically makes up about 15 percent of the PCC mixture by weight. Portland cement is manufactured by crushing, milling, and blending selected raw materials containing appropriate proportions of lime, iron, silica, and alumina. Most Portland cement particles are less than 0.045 mm (No.325 sieve) in diameter.

Portland cement combined with water forms the cement paste component of the concrete mixture. The paste normally constitutes about 25 to 40 percent of the total volume of the concrete. Air is also a component of the cement paste, occupying from 1 to 3 percent of the total concrete volume, up to 8 percent (5 to 8 percent typical) in air entrained concrete.

In terms of absolute volume, the cementing materials make up between about 7 and 15 percent of the mix, and water makes up 14 to 21 percent. Supplementary cementitious materials are sometimes used to modify or enhance cement or concrete properties. They typically include pozzolanic or self-cementing materials.

Pozzolanic materials are materials comprised of amorphous siliceous or siliceous and aluminous material in a finely divided (powdery) form, similar in size to Portland cement particles, that will, in the presence of water, react with an activator, typically calcium hydroxide and alkalis, to form compounds possessing cementitious properties.

Descriptions of various kinds of pozzolans and their specifications are provided in ASTM C618. Self-cementing materials are materials that react with water to form hydration products without any activator. Supplementary cementitious materials can affect the workability, heat released during hydration, the rate of strength gain, the pore structure, and the permeability of the hardened cement paste.

Coal fly ash that is produced during the combustion of bituminous coals exhibits pozzolanic properties. Silica fume is also a pozzolanic material consisting almost entirely (85 percent or more) of very fine particles (100 times smaller than Portland cement) that are highly reactive. Coal fly ash produced during the combustion of subbituminous coal exhibits self-cementing properties (no additional activators, such as calcium hydroxide, are needed).

Similarly, ground granulated blast furnace slag reacts with water to form hydration products that provide the slag with cementitious properties. Coal fly ash and ground granulated blast furnace slag can be blended with Portland cement prior to concrete production or added separately to a concrete mix (admixture).

Silica fume is used exclusively as an admixture. Chemical and Mineral Admixtures An admixture is a material, other than Portland cement, water and aggregate, that is used in concrete as it is mixed to modify the fresh or hardened concrete properties. Chemical admixtures fall into three basic categories.

They include water-reducing agents, air-entraining agents, and setting agents. Chemical admixtures for concrete are described in ASTM C494. Water-reducing agents are chemicals that are used to reduce the quantity of water that needs to be added to the mix, at the same time producing equivalent or improved workability and strength.

  1. Air entrainment increases the resistance of concrete to disintegration when exposed to freezing and thawing, increases resistance to scaling (surface disintegration) that results from deicing chemicals, increases resistance to sulfate attack, and reduces permeability.
  2. Air entrainment can be accomplished by adding an air-entraining admixture during mixing.

There are numerous commercial air entraining admixtures manufactured. Descriptions and specifications are described in ASTM C260. Setting agents can be used to either retard or accelerate the rate of setting of the concrete. Retarders are sometimes used to offset the accelerating effect of hot weather or to delay the set when placing of the concrete may be difficult.

MATERIAL PROPERTIES AND TESTING METHODS Concrete Aggregate Since aggregates used in concrete mixtures comprise approximately 80 to 85 percent of the concrete mixture by mass (60 to 75 percent of the concrete mixture by volume), the aggregate materials used have a profound influence on the properties and performance of the mixture in both the plastic and hardened states. The following is a listing and brief comment on some of the more important properties for aggregates that are used in concrete paving mixtures:

Gradation – the size distribution of the aggregate particles affects the relative proportions, cementing materials and water requirements, workability, pumpability, economy, porosity, shrinkage, and durability. The size distribution of the aggregate particles should be a combination of sizes that results in a minimum of void spaces. Absorption – the absorption and surface moisture condition of aggregates must be determined so that the net water content of the concrete can be controlled. Particle Shape and Surface Texture – the particle shape and surface texture of both coarse and fine aggregates have a significant influence on the properties of the plastic concrete. Rough textured, angular, or elongated particles require more water to produce workable concrete than smooth, rounded, compact aggregates, and as a result, these aggregates require more cementing materials to maintain the same water-cement ratio. Angular or poorly graded aggregates may result in the production of concrete that is more difficult to pump and also may be more difficult to finish. The hardened concrete strength will generally increase with increasing coarse aggregate angularity, and flat or elongated coarse aggregate particles should be avoided Rounded fine aggregate particles are more desirable because of their positive effect on plastic concrete workability. Abrasion Resistance – the abrasion resistance of an aggregate is often used as a general index of its quality. Durability – resistance to freezing and thawing is necessary for concrete aggregates, and is related to the aggregate porosity, absorption, permeability, and pore structure. Deleterious Materials – aggregates should be free of potentially deleterious materials such as clay lumps, shales, or other friable particles, and other materials that could affect its chemical stability, weathering resistance, or volumetric stability. Particle Strength – for normal concrete pavements, aggregate strength is rarely tested. It is usually much greater than and therefore not as critical a parameter as the paste strength or the paste-aggregate bond. Particle strength is an important factor in high-strength concrete mixtures.

Portland Cement and Supplementary Cementitious Materials Although it comprises between only 7 to 15 percent of the absolute volume of concrete mixture, it is the hardened paste that is formed by hydration of the cement upon the addition of water that binds the aggregate particles together to form a stonelike mass.

Chemical Composition – differences in chemical composition, particularly with supplementary cementitious materials that could be less uniform than Portland cement, could affect early and ultimate strengths, heat released, setting time, and resistance to deleterious materials. Fineness – the fineness of the cement or supplementary cementitious materials affects heat release and rate of hydration. Finer materials react faster, with a corresponding increase in early strength development, primarily during the first 7 days. Fineness also influences workability, since the finer the material, the greater the surface area and frictional resistance of the plastic concrete. Soundness – refers to the ability of the cement paste to retain its volume after setting, and is related to the presence of excessive amounts of free lime or magnesia in the cement or supplementary cementitious material. Setting Time – the setting time for the cement paste is an indication of the rate at which hydration reactions are occurring and strength is developing and can be used as an indicator as to whether or not the paste is undergoing normal hydration reactions. False Set – false set or early stiffening of the cement paste is indicated by a significant loss of plasticity without the evolution of heat shortly after the concrete is mixed. Compressive Strength – compressive strength is influenced by cement composition and fineness. Compressive strengths for different cements or cement blends are established by compressive strength testing of mortar cubes prepared using a standard graded sand. Specific Gravity – specific gravity is not an indication of the quality of the cement, but is required for concrete mix design calculations. The specific gravity of Portland cement is approximately 3.15.

Table 24-6 provides a list of standard laboratory tests that are presently used to evaluate the mix design or expected performance of Portland cement and supplementary cementitious materials for use in concrete paving mixtures.

CONCRETE PAVING MATERIAL The mix proportions for concrete paving mixtures are determined in the laboratory during mix design testing. This involves determination of the optimum characteristics of the mix in both the plastic and hardened states to ensure that the mix can be properly placed and consolidated, finished to the required texture and smoothness, and will have the desired properties necessary for pavement performance.

Slump – slump is an indication of the relative consistency of the plastic concrete. Concrete of plastic consistency does not crumble but flows sluggishly without segregation. Workability – workability is a measure of the ease of placing, consolidating, and finishing freshly mixed concrete. Concrete should be workable but not segregate or bleed excessively. Setting Time – knowledge of the rate of reaction between cementing materials and water (hydration) is important to determine setting time and hardening. The setting times of concrete mixtures do not correlate directly with the setting times of the cement paste because of water loss and temperature differences. Air Content – the amount of entrapped or entrained air in the plastic concrete can influence the workability of the concrete mixture and reduce its propensity for bleeding.

Hardened Concrete

Strength – concrete pavements must have adequate flexural strength to support the design traffic loads (repetitions of loaded axles) that will be applied over the service life of the facility. While compressive strength can also be measured, flexural strength is more relevant to the design and performance of concrete pavements. Density – the density of concrete paving mixes varies depending on the amount and relative density of the aggregate, the amount of air that is entrained or entrapped, and the water and cementing materials content of the concrete. Durability – the hardened concrete pavement must be able to resist damage from freezing and thawing, wetting and drying, and chemical attack (e.g., from chlorides or sulfates in deicing salts). Air Content – the finished and cured concrete should have adequate entrained air in the hardened cement paste to be able to withstand cycles of freezing and thawing. Frictional Resistance – for user safety, the surface of an exposed concrete pavement must provide adequate frictional resistance and resist polishing under traffic. Frictional resistance is a function of the aggregates used and the compressive strength of the concrete. Volume Stability – concrete paving mixtures must be volumetrically stable and must not expand due to alkali aggregate reactivity. Concrete paving mixtures should not shrink excessively upon drying.

Is PCC a cement?

Plain cement concrete is a cement mixture commonly used for paving and flooring and is also known as PPC. It is one of the most important elements in a building structure. PCC is laid on the soil surface and acts as a shield for the reinforced concrete against direct contact with soil and water. Why We Use Pcc In Construction

Is PCC required curing?

Polymer-cement concrete should be first cured in the wet conditions for effective hydration of Portland cement and then in air-dry conditions for polymer setting. According to the literature, the often accepted curing regime of PCC covers 5 days of wet curing and then the air-dry curing until the time of testing.

Why is RCC construction preferred today?

Benefits of RCC construction over brick and mortar buildings – TMT Steel Rods It is the 21st century, and RCC constructions have replaced traditional brick and mortar style of buildings for most constructions. RCC stands for Reinforced Cement Concrete, which has steel cores, around which the cement-concrete matrix is poured.

Load bearing path and capacity: RCC constructions have a longer load bearing path due to its strong Steel core while the brick structures lack this strength. When the load is multiplied for construction of higher stories, or during seismic activity, RCC constructions are practically better resilient due to their strength. This strength is multiplied due to high-quality TMT Steel rods that reinforce the cement concrete mixture. Even blocks survive better than the bricks. The mortar has to be replaced in every 5-10 years depending on exposure to moisture, loads and impacts. The RCC constructions can thus bear the loads for a large number of stories, compared to brickworks due to high load-bearing capacity. Versatile Structures: The actual size of a construction is measured by the square inch area of the indoor rooms. The columns bear most of the weight, so it’s possible to minimize the number of walls in RCC, and even large halls or auditoriums are effortlessly constructed. Brickworks needs walls that bear their loads and thus results in smaller rooms’ size. Developments in lifestyle choices, construction industry, and commercial sector have resulted in preference to RCC for the same benefit of larger spaces and customized structures. The depth of foundation: Brickworks need deeper trenches as a foundation to achieve better stability for their structures. RCC need lesser excavation for inserting TMT steel rods as reinforcements are over the ground, with a concrete cement mixture. This is because of the superior grip of TMT rods over concrete, then mortar has over brick. The lower brickworks also degrade over time, resulting in weaker bases and eventual failures. Costs : Brickworks are cheaper compared to RCC if constructed for 2 stories or less. But overall costs including skilled labour, material costs, and wall areas result in an expensive construction for brick and mortar. The longevity of the RCC buildings makes them a cost-effective option in the long run. Durable and Reliable: With the sturdiness of the Steel centre, RCC forms stronger bonds that stand strong during a catastrophe or tragic calamities. Brick and mortar structures have the deficit of a stronger core and bond that can withstand strong forces, therefore making them less reliable. RCC constructions are therefore more durable and reliable for life and property.

These are few of the many reasons why RCC constructions are slowly rendering brickworks extinct and only used for aesthetic appeal. The RCC is the future of construction technology, with a rapidly transforming industry to backbone its promises. India’s construction industry is a large contributor to its rising GDP and economy, and exports steel, cement, finished products, etc.

What are the advantages of RCC floors?

Why Do We Use Reinforced Concrete Floors? – There are many reasons why reinforced concrete flooring is so popular amongst our customers through the UK:

Regular concrete can be brittle with relatively poor tensile strength in comparison to reinforced concrete.Reinforced concrete is used to ensure your concrete flooring remains resistant to damage such as cracking, bending, or the ravages of time.Steel and concrete react to thermal changes in similar ways to each other, which means that any internal stress is avoided.Reinforced concrete flooring has a better tensile strength than regular concrete and is also more durable with a higher compression strength, too. Any stress placed on a reinforced concrete floor is transferred to the steel rods, which means that the floors can carry much more weight than regular concrete.

What are the advantages of RCC over other construction materials?

Advantages of Reinforced Concrete –

Reinforced concrete has a high compressive strength compared to other building materials. Due to the provided reinforcement, reinforced concrete can also withstand a good amount tensile stress. Fire and weather resistance of reinforced concrete is fair. The reinforced concrete building system is more durable than any other building system. Reinforced concrete, as a fluid material, in the beginning, can be economically molded into a nearly limitless range of shapes. The maintenance cost of reinforced concrete is very low. In the structure like footings, dams, piers etc. reinforced concrete is the most economical construction material. It acts like a rigid member with minimum deflection. As reinforced concrete can be molded to any shape required, it is widely used in precast structural components. It yields rigid members with minimum apparent deflection. Compared to the use of steel in structure, reinforced concrete requires less skilled labor for the erection of the structure.
