Which cement set fast OPC or PPC?

Setting time of PPC us higher than OPC. Its initial setting time is 30 minutes and final setting time is 600 minutes. Its slower setting time helps to get better finishing. OPC has finiteness of 225 sq.

Which one is better OPC or PPC cement?

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 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.

What is the advantage of PPC over OPC?

PPC has high durability than OPC which means the structure will last longer and have longer life. 04. PPC is more resistant towards the attack of sulphates, alkalies, chlorides and chemicals as compared to OPC.

What is difference between OPC cement and PPC cement?

OPC cement is made by adding limestone, gypsum and other raw like argillaceous, calcareous materials. PPC Cement is prepared by adding Pozzolanic materials to OPC Cement. The preliminary strength of OPC is larger than PPC, however for a longer period of time. The strength of PPC is larger.

Why Pozzolana portland Cement PPC is more popular | PPC Vs OPC | Benefit of PPC Cement

How long does PPC cement take to dry?

Setting time of PPC us higher than OPC. Its initial setting time is 30 minutes and final setting time is 600 minutes. Its slower setting time helps to get better finishing.

What is the disadvantage of PPC cement?

Disadvantages of Portland Pozzolana Cement

The initial strength obtained is less, which effect the de-shuttering of supports early. As it contains more fine material, handing of concrete is difficult.

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 for construction?

Can we use PPC cement for slab?

Portland pozzolana cement (PPC) is used for the construction of houses, schools, and residential building slabs. PPC is cheaper than ordinary Portland cement. Thus to reduce the building making cost, PPC should be adopted. Both the PPC and OPC cement is used in the construction of slabs.

Why is PPC cement used?

PPC is special blended cement useful in general construction work and is especially suitable for applications in aggressive environmental conditions. It can be confidently employed in construction of hydraulic structures, marine works, mass concreting such as dams, dykes, retaining walls foundations and sewage pipes.

Which cement is best for plastering?

Best cement for plastering:- Best cement for plastering used in construction is OPC- 43 (Ordinary Portland cement grade 53) and PSC (Portland slag cement) brand of UltraTech Cement, ACC gold water shield, ACC Suraksha power, Ambuja Cement, Sagar cement, Dalmia Cement, Shri cement, Birla cement, etc.

Which 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.

Which grade of OPC is best?

OPC 53 grade Cement

OPC 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.

Can we use PPC cement for footing?

So PPC cement is new variant of OPC cement. Both cements are widely used for the various purpose like beam, slab, concrete manufacturing, brick block, footing and retaining wall formation. And both OPC and PPC cement are eco-friendly in nature.

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.

Which cement is best for columns and beams?

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.

Where is quick setting cement used?

It is used in under-water construction, in running water conditions, in rainy & cold weather conditions, in anchoring & tunnelling and also where quick strength is needed in short span of time.

What is rapid hardening cement?

Rapid Hardening Portland Cement (RHPC) is a special purpose cement used in concrete to achieve a higher rate of early strength development, compared to using Normal Cement. The improved early performance of RHPC is achieved principally through increased product fineness.

Is PPC cement sulphate resistant?

Advantages of PPC (Portland Pozzolana Cement)

(ii) PPC is highly resistant to sulphate attacks and hence used in construction of dams, foundations and buildings nearby the sea shore, reservoirs and marine constructions.

Where is OPC cement used?

Where OPC is used- OPC is widely used for the construction of high-rise buildings, roads, dams, bridges, flyovers where high strength and fast setting is required. Portland Pozzolana Cement (PPC) is manufactured by a combination of pozzolanic materials.

Does PPC cement have grade?

There are no grades in PPC or in any other type of cement. 43 S grade and 53 S grade of cement are used in Railway Engineering for manufacture of sleepers. Here, S stands for Sleepers. OPC 33 grade, 43 grade and 53 grade cements are used for General purpose engineering such as building construction.

Which cement is best in India?
