What is the meaning of grade in cement?

Types of Cement Grades: – The grade indicates the strength of cement. Strength is generally measured as compressive strength. Before buying the cement, you should check the grades because it highly affects the strength of your structure. These are the types & grades available in the Market.

How do you calculate cement grade?

Points to Check on a Cement Bag before Buying It Author: Admin Date:18/06/2018 In 33 Grade Cement What Does The Number 33 Represent Cement is the most important construction material which is used widely. Cement is generally used to prepare concrete and mortar which are used to make RCC framed structures. Cement has binding properties and can easily mix with aggregates and forms a homogeneous mixture, which hardens to give a stone-like strength.

The strength and durability of the structure are mainly dependent on strength of cement. There are several makers of cement worldwide. Persistently they adopt unhealthy practices to manufacture and pack cement to extend their profits. The price of cement is quite alternative construction materials (coarse aggregates, fine aggregates etc.) and it conjointly affects your overall project value.

Hence we must be aware before buying cement bags because sometimes cement bags arriving on the site may be a duplicate. Duplicate or adulterated cement will decrease the life of the structure. You have to check some basic standard specifications before you buy it.

Check the manufacturer’s name and their registered trademark. If the trademark and name is not printed properly or there is any spelling mistake, then the cement bag may be duplicated.

ISI mark should be printed on the cement bags in black color. That confirms that the cement packed in the bag has fulfilled every requirement as mentioned in its specifications.

The most important point to check on a cement bag is its grade and type of cement. The cement bag of OPC 53 must mentioned the words ‘Ordinary Portland Cement, 53 Grade ‘or‘ Ordinary Portland Cement, 53-S Grade whichever is applicable.

The net weight of cement in kg i.e.25 Kg, 50 Kg etc. must be mentioned on the cement bag.

Check the brand of cement. It is important that the cement is of a reputable brand. One must also check the cut-sheet provided by the brand, to know the technical details about the product.

MRP (Maximum Retail Price) is an important thing to check on a cement bag. The retailer or seller can fool us by selling the cement bag for more price than MRP. Hence checking the MRP before buying the cement bag will help the consumer to avoid any kinds of frauds.

Words ‘Use no Hooks’ or its symbol are printed on standard cement bag.

The batch/control unit number in terms of week, month and year of packing must be mentioned on the cement bag. It is preferred to use a cement bag which is recently packed, usually less than 3 months.

The above points are essential to check on a cement bag, before buying it. This will help to ensure the cement bags are from a standard manufacturer or seller and helps in avoiding any loss to the customer. After buying cement bags, they must be properly stored and used within few days. : Points to Check on a Cement Bag before Buying It

What is PPC cement full form?

Portland Pozzolana Cement (PPC) PPC is a type of blended cement. It consists of 15-35% pozzolanic material, 4% gypsum and the rest is clinker. PPC as per BIS code is equivalent to that of 33 grade. Since the pozzolanic material reacts with calcium hydroxide liberated by the hydrating Portland cement and forms cementatious compounds, PPC makes the concrete more impermeable and denser.

What is 35A concrete?

Design of Water Retaining Structures – The design of water retaining structures is carried out in accordance with BS 8007. Crack width is the limiting criteria in this design. Generally, the concrete structures are designed to the maximum crack width of 0.3mm.

But in case of the water retaining structures, the water tends to pass through the cracks developed on the surface which must be eliminated through the design. However, the concrete itself can filled the crack developed through the process called Self-healing up to 0.2mm crack width. So that concrete will become watertight within few days while exposed to water.

Therefore, in case of the water retaining structures, the maximum crack width is limited to 0.2mm to achieve the water tightness by self-healing or 0.1mm if the appearance is the matter in the design procedure. The 35A concrete grade is used for the water retaining structures which is expected to have a high durability while keeping the strength as Grade 35.
