What is the difference between ordinary Portland cement and rapid hardening Portland cement?

What is the difference between ordinary Portland cement and rapid hardening Portland cement?

Rapid Hardening Portland Cement  Rapid Hardening Portland Cement (RHPC) is similar to ordinary cement but with higher tri-calcium silicate (C3S) content and finer grinding. It gain strength more quickly than OPC, though the final strength is only slightly higher.

What is rapid hardening cement used for?

Rapid hardening cement is used in areas like road pavements so that the traffic can be opened early. It is also used in manufacturing precast slabs, posts, electric poles, concreting in cold countries.

What is ordinary portland cement used for?

Its uses include pavements and sidewalks, reinforced concrete buildings, bridges, railway structures, tanks, reservoirs, culverts, sewers, water pipes and masonry units.

What is Portland slag cement?

Portland Slag Cement, commonly known as PSC, is blended cement. It is created with a combination of upto 45- 50\% slag, 45\% – 50\% clinker, and 3-5\% gypsum. PSC has been voted as the most suitable cement for mass construction because of its low heat of hydration.

The difference between the quick setting cement and rapid hardening cement is that quick-setting cement sets earlier. At the same time, the rate of gain of strength is similar to Ordinary Portland Cement, while quick hardening cement gains strength quickly. Formworks in both cases can be removed earlier.

What’s the difference between Type 1 and Type 2 Portland cement?

Portland Cement is a type of cement, not a brand name. Many cement manufacturers make Portland Cement. Type 1 is a general use cement. Type 2 – Is used for structures in water or soil containing moderate amounts of sulfate, or when heat build-up is a concern.

What type of cement should be preferred in water log areas?

The type of cement used for most construction, including underwater construction, is Portland cement. Made from heated clay and lime, Portland cement is the secret to concrete’s ability to set underwater.

What is the difference between portland cement and ordinary cement?

Portland Pozzolana Cement is a variation of Ordinary Portland Cement. Pozzolana materials namely fly ash, volcanic ash, are added to the OPC so that it becomes PPC. PPC is cheaper than OPC. PPC has low initial setting strength compared to OPC but hardens over a period of time with proper curing.
