What is the Variation Between OPC and PPC?

The final setting time of OPC Cement is comparatively lower than PPC Cement, which makes it effective for your construction. OPC generates more heat during hydration reactions making it unsuitable for mass casting. While PPC has a slow hydration process due to which heat generation is comparatively lower. OPC Cement is less durable in aggressive weather as compared to PPC Cement. Cost-wise while comparing OPC and PPC, OPC Cement is costlier than PPC Cement, which makes PPC

Difference Between OPC and PPC Cement

Portland Pozzolana Cement (PPC) is a variation of OPC which includes a mixture of a pozzuolanic material which can increase the strength of the concrete and reduce the amount of OPC used. OPC is produced simply by grinding to a powder limestone and secondary materials; PPC is the result of adding pozzuolan or similar materials such as volcanic ash, clay, slag, silica, fume, fly ash, or shale with OPC.

OPC vs PPC - Difference Between OPC and PPC

The durability of concrete made using OPC cement is less than that of concrete made using PPC cement. Whereas the durability of concrete made using PPC is higher than OPC which means the structure made up of PPC will last longer. Curing time. OPC requires a minimum curing period of 7 days. When OPC is exposed to hot and dry weather condition the minimum curing period required shall not

Strength of OPC and PPC From the above data we can conclude that initial strength of OPC cement is higher than PPC cement. But for long term strength, Portland Pozzolana Cement is higher than Ordinary Portland Cement. So, it is clear now if you need higher strength in initial stage then go for OPC otherwise go for PPC.

Setting time of OPC is lower than PPC. Its initial setting time is 30 minutes and final setting time is 280 minutes. Its faster setting time helps faster construction. OPC cement is more costly than PPC. OPC is not favorable in aggressive weather. Initial strength is higher than PPC. OPC has finiteness of 225 sqm/kg. It has lower fineness than PPC; therefore it has higher permeability resulting in lower durability.

What is the difference between OPC and PPC

Flyash based cement (PPC) is recommended for brick masonry, plastering, tiling and waterproofing works. In these works, strength is not the major criteria. PPC has an edge on OPC as PPC has slower rate of heat of hydration. Thereby PPC is prone to less cracks reduced shrinkage), better workability and finishing (as fly ash based cement are spherical in shape and finer in size).

Ordinary Portland Cement: Uses, Advantages

It cannot be used for large-scale concreting because it has a higher heat of hydration than PPC. The durability of OPC is lower than the PPC. It produces relatively less solid concrete than PPC, so pumping the concrete becomes a bit difficult. The OPC is finer hence higher permeability and consequently lower durability. OPC is expensive than PPC. Uses of ordinary portland cement:
