Which cement is better PPC or OPC?

Both OPC and PPC cements are good for construction of concrete slab. OPC is the most commonly used cement in industrial and large construction, PPC is most commonly used for small residential constructions. OPC cement hardens faster than PPC, has higher heat of hydration and thus it requires more care in curing.

Where 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.

What is the advantage of PPC over OPC?

It generates less heat of hydration at a low rate than ordinary Portland cement. Reduction in permeability of PPC offers many other advantages, such as better durability than opc 53 cement.

Which type of cement is best for home 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 cement is best for roof concrete?

There is three types of cement available in market or ordinary Portland cement (OPC) Portland slag cement (PSC) and portland pozzolana cement (PPC). OPC 53 and PPC ( Portland pozzolana cement) of all brand are the best cement for rcc roof slab construction in india,bihar and jharkhand.

What is PPC cement?

Portland Pozzolana Cement
Portland Pozzolana Cement (PPC) is manufactured by a combination of pozzolanic materials. Pozzolana is an artificial or natural material that has silica in it in a reactive form. Along with pozzolanic materials in specific proportions, PPC also contains OPC clinker and gypsum.

What is PPC grade cement?

PPC is considered to have strength equivalent to that of OPC 33 grade cement. Therefore, its strength is 330 kg per sq cm. These are the minimum strength requirements for each grade and type of cement to win ISI mark.

Which has more strength OPC or PPC?

The initial strength is less but for longer duration, the strength of PPC is comparatively higher than OPC. OPC generates more heat after mixing with the water which makes OPC is not suitable for mass casting. PPC has a slow hydration process due to which heat generation is comparatively lower.

What is the difference between OPC and PPC in construction?

For example RCC casting of buildings, mass concreting for bridges and even plastering and other non-structural works. Lower than PPC. Its initial setting time is 30 minutes and final setting time is 280 minutes. Its faster setting time helps faster construction. Setting time of PPC us higher than OPC.

What are the advantages of OPC cement?

Advantages of OPC (Ordinary Portland Cement) (i) Due to its shorter setting time (compared to PPC), OPC is recommended in projects where props are to be removed early. (ii) Higher initial strength compared to PPC. (iii) Shorter curing period, and as a result low curing costs.

What is the difference between PPC and ordinary cement?

PPC is economical and costs lower than other materials. A 50 kg bag of the Portland pozzolana cement gives more volume of mortar than ordinary Portland cement as the fly ash is finer and of lower density. After curing PPC achieves the strength equivalent to grade 33 ordinary Portland cement.

What is the difference between pozzolana cement and OPC?

Both are ecofriendly materials but Pozzolana Cement uses natural and industrial waste thus reducing the environmental pollution. OPC is available in 3 grades namely grade 33, grade 43 and grade 53. Pozzolana is available in one grade and its strength matches the strength of grade 33 OPC after curing.
