What is cement? National Cement

Cement is the main component of concrete. It's an economical, high-quality construction material used in construction projects worldwide. Cement is made by grinding together a mixture consisting mostly of limestone and aluminium and silica oxides, which is heated at a temperature of 1,450°C. The result is a granular substance called "clinker," which is then ground into the fine gray powder

Cement and Cement Additives Structural Guide

These ingredients, when heated at high temperatures form a rock-like substance that is ground into the fine powder that we commonly think of as cement. Process of making the cement can be briefly outlined as follows. Raw material extraction from the quarry; Grinding, proportioning and blending; Pre-heated phase; Kiln phase; Cooling and Final

CEMENT RAW MATERIALS CemNet

Finished cement is produced by finely grinding together around 95% cement clinker with 5% gypsum (or anhydrite) which helps to retard the setting time of the cement. The quality of cement clinker is directly related to the chemistry of the raw materials used. Around 80–90% of raw material for the kiln feed is limestone. Clayey raw material accounts for between 10–15%, although the precise
