Portland Composite Cement. This product is a type of blended cement obtained by grinding portland cement clinker with a little amount of limestone as a mineral additive and a setting regulating agent. It can be used in areas where portland cement is used. As it contains additives, its heat of hydration is lower in comparison with portland cement.

Having a higher percentage of C 3 A, cement sets quickly, and releases a high heat of hydration. C 3 S gives the cement its initial strength, and makes it harden rapidly. On the other hand, C 4 AF has little to do with strength, but imparts the gray color to ordinary Portland cement. ‘Heat of hydration’ is the term used to describe the heat released when cement reacts with water during the ...

Portland cement is a hydraulic type of cement (hardens with the reaction with water). Also, water will increase the flow ability of the concrete, but excess water content in the concrete will cause cracks. Air: Tiny air bubbles actually provide extra room to the water molecules while freezing. Also air helps preventing crack formation in concrete.

La mise au point du ciment Portland a été le fruit des recherches assidues effectuées dans les milieux de la science et de l'industrie, au xixe siècle, pour produire un ciment naturel de qualité supérieure. En 1817, le Français Louis Vicat découvrit le principe de l'hydraulicité des chaux et publia ses travaux sans prendre de brevet.

Granulated Blast Furnace Slag (GBFS) is one of the waste material groups obtained from various metallurgy plants. In production of raw iron, blast furnace slag remains above raw iron due to having less weight and iron ore gangue is composed at a temperature between 1,400 to 1,600 °C after burning of coke and limestone.
