Which Grade Cement Is Best For Concrete?

Which Grade Cement Is Best For Concrete
OPC Grade Cement- – OPC means Ordinary Portland Cement is a fully automated and dry manufacturing process. It is available in two different grades-OPC-43 & OPC-53. OPC-43 : This type of cement is used for plain concrete work and plastering works. OPC-53: This type of cement is used for the structural purposes as in reinforced cement concrete.

Can we use 43 grade cement concrete?

43 grade cement means that the compressive strength of the cement after 28 days is 43 N/mm3 when tested. This grade of cement is used for plain concrete work and plastering works. It is suitable to make concrete mix up to M30.43 grade cement is also used to make precast items, such as tiles, blocks, pipes, etc. It can be used where setting time is not a necessary concern.

What is OPC and PPC cement?

Difference Between OPC and PPC Cement Sheikh Anwarul Mahdi PPC cement full form is Portland Pozzolana Cement, OPC cement full form is Ordinary Portland Cement, Both PPC and OPC cement is used in construction. PPC cement is a variant of OPC cement. These two types of cement differ from each other in terms of component, strength, heat generation, the percentage of several components, durability, grades, cost, eco-friendly nature, application, setting time, curing period, etc.

Sources OPC Cement PPC Cement
1 Definition/ Components A mixture of limestone and other raw materials like argillaceous, calcareous, and gypsum is prepared and then grinded to prepare OPC (Ordinary Portland Cement). PPC (Portland Pozzolana Cement) is prepared by adding Pozzolanic materials to OPC. So, the main components are OPC, gypsum, and pozzolanic materials (15~35%) which include calcined clay, volcanic ash, fly ash, or silica fumes.
2 Strength Initial strength is higher than PPC. PPC concrete has higher strength than OPC concrete over a longer period of time.
3 Heat of hydration Generates more heat than PPC in hydration reaction which makes it less suitable for mass casting. It has a slow hydration process and thus generates less heat than OPC.
4 Durability OPC concrete is less durable in aggressive weather. PPC concrete is more durable in aggressive weather.
5 Cost Costlier than PPC. Cheaper than OPC.
6 Environmental Impact Emits CO 2 during the manufacturing process. It constitutes industrial and natural waste which makes it eco-friendly.
7 Application/ It is suitable where fast construction is required but not suitable for mass concreting due to heat issues as mentioned above. It is suitable for all types of construction work. For example RCC casting of buildings, mass concreting for bridges, and even plastering and other non-structural works.
8 Setting Time Lower than PPC. Its initial setting time is 30 minutes and the final setting time is 280 minutes. Its faster setting time helps faster construction. The setting time of PPC portland is higher than OPC. Its initial setting time is 30 minutes and the final setting time is 600 minutes. Its slower setting time helps to get better finishing.
9 OPC has finiteness of 225 sq.m/kg. It has lower fineness than PPC. So, it has higher permeability resulting in lower durability. OPC has finiteness of 300 sq.m/kg. It has higher fineness than OPC. So, it has lower permeability resulting in higher durability.
10 Grades available 33 Grade, 43 Grade, and 53 Grade OPC cement are available. No specified grade of PPC cement is available.
11 Lower than PPC. Higher than OPC.
12 Resistance against chemical attack It has lower resistance against alkalis, sulfates, chlorides, etc. It has higher resistance against alkalis, sulfates, chlorides, etc.

Difference Between OPC and PPC Cement

Can we use 53 grade cement for plastering?

What are the best cement types for plastering in india – Ordinary Portland cement (OPC),Portland slag cement (PSC) and Portland pozzolana cement (PPC) are available in Indian market and are used for plastering work. The best cement are OPC 43 and PSC used for small scale residential building of wall plastering in India and for Industrial, multi storey building, dams Bridge, OPC 53 and PPC are being used.

  • Now discuss about different types of cement best for plastering.
  • Plaster ke liye best cement is OPC 43 & PSC used for low rise residential building & for high rise building OPC 53 is best to used.
  • Best cement for plastering is OPC 43 & PSC used for low rise residential building & for high rise building OPC 53.

OPC43 is the best cement used for plastering of low residential building & OPC 53 is best cement for plastering of high rise building in india.1) OPC:- ordinary Portland cement that is also known as in short form OPC, OPC is available in market in 3 grade 33, 43 and 53.

But out of OPC grade, OPC43 is the best cement used for plastering in India for residential building and 53 is best cement for plastering of high rise building,it has long lasting and life. But the most best cement is OPC 43 used for plastering work,Although OPC-53 is good but sometimes it’s causes cracks and shrinkage of plastering but it has high strength and long lasting and life that’s why OPC-53 used for high rise building, dams and Bridge for plastering work.2) PSC:- it is Portland slag cement basically used in coastal areas of building for plastering work to prevent from salty water and most harmful chemical agents that is present in coastal areas due to oceans.3) PPC:- it is Portland pozzolana cement generally it is used as plaster work in high rise building structure bridge and dams, because bridge and dams retaining walls always in make contact with running water and standing water and there is harmful chemical agents like alkalis, acids,Salt present in water and try to react with cement brick wall.

33 Grade vs 43 Grade vs 53 Grade of Cement

To prevent from corrosion and chemical reaction between retaining wall and water soluble harmful chemicals PPC is best plastering material for high rise structure bridge and dams. ◆You Can Follow me on Facebook and Subscribe our Youtube Channel You should also visits:- 1)what is concrete and its types and properties 2) concrete quantity calculation for staircase and its formula 3) how to calculate weight of mild steel plate and derive its formula 4) calculate quantity of cement Sand for brickwork of 10m3 5) cement calculation in tile work of hundred square foot area 6) weight calculation of Steel bar and its formula 7) what is admixture of concrete and its types and its properties
