Cement Wikipedia

Cement materials can be classified into two distinct categories: non-hydraulic cements and hydraulic cements according to their respective setting and hardening mechanisms. Hydraulic cements setting and hardening involve hydration reactions and therefore require water, while non-hydraulic cements only react with a gas and can directly set under air. By far the most common type of cement is hydraulic cement, which hardens by hydration of the clinker

What is Cement? History- Chemistry- Industries Civil

Cement, one of the most important building materials, is a binding agent that sets and hardens to adhere to building units such as stones, bricks, tiles, etc. Cement generally refers to a very fine powdery substance chiefly made up of limestone (calcium), sand or clay (silicon), bauxite (aluminum) and iron ore, and may include shells, chalk, marl, shale, clay, blast furnace slag, slate.
