What is OPC 33 grade cement?

OPC 33-grade cement means ordinary portland 33-grade cement. In these, the number 33 represents the compressive strength of cement at end of 28 days of curing and tested as per Indian standard code recommendation.

What does 33 43 and 53 grades of cement mean?

By the grade of cement as 33/43/53, the values 33/43/53 indicate the compressive strength of cement cube in Mpa (N/mm2) after 28 days of curing, where cement mould size is 7.06 cm*7.06 cm*7.06 cm. However, it would be good to understand the logic and basis of arriving at such values.

What is the use of 33 grade cement?

33-grade cement is commonly used for making concrete of low strength such as below M20 concrete grade. 43-grade cement is used in PCC and RCC works, preferably where the grade of concrete up to M30. Also, it is recommended for plastering, tiling, brickwork and stone masonry, flooring, pathway etc.

Which cement is better 33 grade or 53 grade and why?

The initial strength of 53 grade cement is higher than 33 grade or 43 grade cement. The strength of 53 grades does not increase much after 28 days due to initial strength increases, while 33 grade and 43-grade cement are gaining strength even after 28 days.

Which grade cement is best for RCC?

OPC 53 Grade cement is recommended in all RCC structures like footing, column, beam and slabs, where ever initial and ultimate strength is the major structural requirement.

33 Grade vs 43 Grade vs 53 Grade of Cement

Which is better OPC or PPC?

PPC cement is generally used for plastering, brick masonry and waterproofing works. PPC has a lower heat of hydration and it is prone to fewer cracks compared to OPC. PPC has lower strength than OPC but PPC provides better workability and finishing than OPC. PPC provides greater resistance to chemicals.

Which is best cement for roof?

The best roof cement in India includes OPC53 grade and PPC cement, brand name Ambuja plus Roof Special Cement, ACC Gold, ACC F2R, Shri Roofon Concrete Master, Ramco Supercrat Cement.

Which cement is best for waterproofing?

Water Repellent Cement is also called Hydrophobic Cement. A small amount of Hydrophobic surfactants such as stearic acid, boric acid or oleic acid is mixed with the ordinary portland cement during grinding of clinker. Hydrophobic Cement is most suitable for basements and for making water tight concrete.

Which grade of cement is best?

Grade 33 and Grade 43 OPC cement are the old grade of cement used for residential construction and nowadays it is replaced by OPC 53 grade of cement. OPC 53 grade cement is the best cement for concrete.

Which cement grade is best for slab?

Ordinary Portland cement of 53 Grade is suitable for all types of RCC structures and is mainly used for the construction of slabs. Because in the Construction of slabs, initial and ultimate strength is the major structural requirement.

Which grade cement is best for house construction?

OPC is the best for house construction in India. Generally, OPC 53 Grade cement is suitable for all RCC structures like footing, column, beam, and slabs, where ever initial and ultimate strength is the major structural requirement.

Which is the is code for 33 grade cement?

Codes for cement grades: Earlier, there used to be three IS codes for different grades of OPC. For OPC 33 grade, the IS code was IS 269 and cement bags were marked with IS 269 mark. For 43 grade OPC, the IS code was IS 8112. The cement bags carrying IS 8112 mark were presumed to be having 43 grade cement.

Which grade cement is normally used for construction of building?

Ordinary Portland Cement or OPC is the most widely used cement grade in the world. It has 3 grades – named as 33, 43, and 53 depending on the compressive strength which is achieved after 28 days of setting. OPC is used for mortar, concrete, stucco, and non-specialty grouts.

Which is better OPC 43 and OPC 53?

OPC 53 sets quicker than OPC 43 and has a quite low initial setting time. It is used in structures where rapid strength gain is required like large load bearing structures like bridges, huge buildings, etc. OPC 43 on the other hand doesn't set so quickly and has a normal initial and final setting time.

Which cement grade is best 43 or 53?

What is OPC and PPC cement?

PPC (Portland Pozzolana Cement) is a variant of OPC (Ordinary Portland Cement.) These two type of cement differs 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.

Which cement is best for bricks?

Flyash based cement (PPC) is recommended for brick masonry, plastering, tiling and waterproofing works. In these works, strength is not the major criteria. PPC has an edge on OPC as PPC has slower rate of heat of hydration.

Which cement is best for foundation?

Which type of cement is best for constructing the foundation? The foundation carries the load of the construction and hence needs to be strong and durable. Portland Pozzolana Cement (PPC) is the ideal cement to be used as it hydrates slowly and gives high final strength.

Which cement is best OPC or PSC?

PSC has the following advantages over OPC. Due to presence of slag, PSC is usually lighter in colour than OPC. The words Portland Slag Cement is written on all PSC cement bags. Further, due to its improved properties, PSC is generally priced higher than OPC in the market.

What do you mix with cement to make it waterproof?

Integral concrete waterproofing systems can be densifiers, water repellents or crystalline admixtures. Densifiers react with the calcium hydroxide formed in hydration, creating another by-product that increases concrete density and slows water migration.

How is Dr Fixit used?

It is used as an additive for cement concrete, mortar and plasters to enhance the properties of cement to impart waterproofing property and thereby provide benefits like no rusting of steel bars, no cracks and no dampness.

Which cement is best for roof plastering?

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.

What is OPC 53 grade cement?

OPC 53 Grade cement is required to conform to BIS specification IS:12269-1987 with a designed strength for 28 days being a minimum of 53 MPa or 530 kg/sqcm. 53 Grade OPC provides high strength and durability to structures because of its optimum particle size distribution and superior crystallized structure.
