Which cement is best OPC or PPC?
Portland Pozzolana Cement (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.
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 cement grade is best for slab?
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.What is meant by 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.33 Grade vs 43 Grade vs 53 Grade of Cement
Which is best cement 43 grade or 53 grade?
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). It is the best choice for all houses, buildings, apartments, and high-rise building construction work.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.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. PPC is best substitute to OPC 43.What is OPC 33 grade cement?
33 Grade OPC cementThey are normally used for general construction purposes. 33 grade cement achieve 33N/mm² (Mpa) at its 28th day after casting. They are commonly used for making concretes which having low strength such as below M20 grade concrete. Note: 33, 43 and 53 are the grades of OPC 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.Where is OPC 53 used?
OPC 53 Grade:The 53 Grade portland cement is not used for ordinary construction works. It is generally used where high strength is needed such as RCC Bridges, Dams, construction of high rise buildings, construction of sleepers ( for railway), etc.
Which cement is better 33 grade or 53 grade and why?
The strength of 53 grade does not increase much after 28 days because of early strength gain. While 33 grade and 43-grade cement continue to gain strength after 28 days. With time 33 and 43-grade cement will attain the same ultimate strength as that of 53-grade cement.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.Which is costly OPC or PPC?
Cost. The cost of OPC is around 300 rupees per bag which is slightly more expensive than PPC. Whereas in the case of PPC, the expensive clinker is replaced by pozzolanic Material such as fly ash hence the price of PPC is slightly less than who OPC.Which grade of OPC is best?
OPC 53 grade CementOPC Cement gives high compressive strength at early ages and at 28 days. A 53 Grade cement gives up to 70 MPa strength against a minimum 53 MPa specified by BIS. So, We can also mix fly ash (at least 20% by weight of cement) in concrete as part replacement of cement at site.
Where is PPC and OPC cement used?
Use of PPC and OPCThey can be reliably utilized in the construction of marine structures, masonry mortars and plastering, hydraulic structures. Besides, they are popularly used in mass concreting works, such as dykes, sewage pipes, dams, etc. PPC is also employed in all other applications where OPC is used.
