FREQUENTLY ASKED QUESTIONS AND ANSWERS
Portland cement clinker is obtained by sintering a precisely defined mixture of raw materials containing calcium oxide (CaO), silicon dioxide (SiO2), aluminum oxide (Al2O3), iron (III) oxide (Fe2O3) and small amounts of other substances, expressed as oxides, at approximately 1450°C.
Portland Cement Clinker is a hydraulic binder obtained by grinding together gypsum, limestone and pozzolanic additives (12-20%) - (21-35%) defined in EN 197-1 standard. The pozzolan admixture used during production increases the workability of concrete and mortar, and is more resistant than Portland cement against reactions that cause expansions and fractures in hardened concrete due to the decrease in the hydration temperature of cement. Due to its reaction with Ca(OH)2 compound formed as a result of hydration reactions, it creates a concrete structure that is non-porous and more resistant to external factors.
