When Portland cement clinker is ground with gypsum, it produces Ordinary Portland Cement (OPC). When the clinker is ground with pozzolana, it creates PPC. Similarly, when the clinker is ground with slag, it produces PSC. PPC and PSC are blended cements that provide improved properties to the ...

There’s the popular Ordinary Portland Cement (OPC), the everyday choice for many builders. Then, there’s the eco-friendly Portland Pozzolana Cement (PPC) with its touch of volcanic ash. For projects in a hurry, Rapid Hardening Cement speeds things up. And if there’s concern about too ...
The principal cementitious material in concrete is portland cement. ... Some of these materials are called pozzolans, which by themselvesdo not have any cementitious properties, but when used with portland cement, react to form cementitious compounds. Other materials, such as slag, do exhibit ceme...
When Portland cement clinker is mixed with gypsum and granulated blast furnace slag in suitable proportions Portland Slag Cement is found. Physical properties of the cement is same as that of OPC,it has low heat of hydration and is relatively better resistant to chlorides, sulphate attack and soi...
