heat balance allows the determination of cement heat of hydration. The standard consistency, the setting times and the soundness of the cement pastes were determined according to the European Standard EN 196-3[20]. The determination of the normal mortar flow was carried out for w/c = 0.5, according to ASTM C1437[21]. Compressive strength
