What is the difference between OPC 53 and 43?

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 is better 43 grade or 53 grade cement?

OPC 53 grade cement has better quality, strength, and less setting time compared to 33 and 43 grades of cement. Due to its high strength, is used for making concrete of higher grade (Above M20).

What is the difference between 53 grade and 43 grade?

53 Grade OPC cement is Used in RCC and pre-stressed concrete of higher grades, cement grouts, instant plugging mortars etc. where initial higher strength is the criteria. 43 Grade OPC Cement is commonly used for plastering works, Non-RCC structures, pathways etc where initial setting time is not of importance.

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.

Which grade of OPC is best?

Ordinary Portland Cement (OPC):

Grade 33 refers to the cement attaining compression strength of 33 Mpa in 28 days of setting. This is same for 43 and 53 grades of cement. Grade 33 and 43 were used for construction in the past. As per IS standard code Grade 53 grade of cement is recommended for house construction.

33 Grade vs 43 Grade vs 53 Grade of Cement

Can we use 43 grade cement for slab?

Can We Use 43 Grade Cement for Slab? Unless a project requires very high strength cement, the use of 43 Grade OPC is generally recommended in general civil construction work such as residential, commercial and industrial structures. It is used in RCC works, preferably where the grade of concrete is up to M-30.

Which cement is best 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.

Is 43 grade cement good for house construction?

43 Grade OPC Cement is recommended for plastering ,tiling , masonry works, Non-RCC structures, pathways etc. where initial days strength is not of prime importance.

Which grade cement is best for concrete?

OPC 53 grade cement is the best cement for concrete.

Which grade cement 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.

Which grade cement is best for tiles?

43 grade cement is generally used for RCC work and slab casting, while 53 grade cement is used for plastering of flooring, tiles, etc.

Which grade cement is best for wall construction?

Ordinary Portland Cement (OPC) 43 Grade Cement:

It is used majorly for wall plastering works, Non-RCC structures, pathways etc. 43-grade cement attains a compression strength of 43 Mpa (megapascals) in 28 days of setting. Make sure that your 43 cement brand adheres to IS 12269 standard code.

Which cement is best for plastering?

What does OPC 43 mean?

OPC 43 means that the cement is expected to reach a compressive strength of 43 MPa in a cube cast by 28 days. Similarly, OPC 53 reaches 53 MPa by 28 days.

Which cement is used for house construction?

The two most commonly used cements for construction are Ordinary Portland Cement (OPC) and Portland Pozzolana Cement (PPC). However PPC cement is more suitable for home construction and especially for critical applications such as Foundations, Columns, and Beams & Slabs.

Why do we use 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.

Which is better OPC or PPC?

OPC is better when you need to cast a slab in a rainy season. OPC (m53) attains strength in a shorter time, while PPC (m43) takes longer. Faster is the drying process, more is the risk of cracking of cement, and therefore it need more care and more amount of water for curing in a lesser time.

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.

Which cement is best for buildings?

The cement types that are good for construction are Ordinary Portland Cement (OPC) and Portland Pozzolana Cement (PPC). OPC has 3 types: 33 Grade for non-RCC, 43 Grade for plastering, and 53 Grade for fast-paced projects. PPC makes the structure denser, making it perfect for mass concreting works.

What is difference between PPC and OPC cement?

PPC has higher strength than OPC over a longer period of time. 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. Less durable in aggressive weather.

How thick should a concrete roof be?

Slabs generally range from 5 to 14 inches in thickness. Spans are up to 35 feet, but may be extended by p o s t - t e n s i o n i n g .

Can we use 43 grade cement RCC?

Unless a project requires very high strength cement, the use of 43 Grade OPC is generally recommended in general civil construction work such as residential, commercial and industrial structures. It is used in RCC works, preferably where the grade of concrete is up to M-30.

What type of cement is used for walls?

All-Purpose Cement: When in doubt, all-purpose cement is a popular option. This is ideal for repairing foundation walls, laying sidewalks, creating steps and setting posts.

What is cement ratio for plastering?

12 MM thick cement mortar in 1:4 ratios is recommended on the walls where smooth side exists. Either 9 or 4.5 MM thick and 15 MM thick cement plaster in 1:4 ratios is recommended on the rough side of the walls. 20 MM thick cement mortar in 1:3 with two coats is recommended in case of vertical Damp Proof Course (DPC).
