Frequently Asked Questions

Portland cement clinker is obtained by sintering a precisely defined mixture of raw materials containing calcium oxide, silicon dioxide, aluminum oxide, iron oxide and small amounts of other materials at approximately 1450°C.

Portland cement is a finely ground inorganic hydraulic binder obtained by grinding Portland cement clinker with gypsum. When mixed with water, it sets and hardens through hydration and preserves its strength and stability even under water.

Portland composite cement is a hydraulic binder obtained by grinding clinker, gypsum, limestone and pozzolanic additions defined in EN 197-1 together. Pozzolanic additions improve workability, reduce hydration heat and support a more durable concrete structure.
