Cement, binding material used in construction and engineering, often called hydraulic cement, typically made by heating a mixture of limestone and clay until it almost fuses and then grinding it to a fine powder. When mixed with water, the silicates and aluminates in the cement undergo a chemical reaction; the resulting hardened mass is then impervious to water. It may also be mixed with water and aggregates (crushed stone, sand, and gravel) to form concrete. Tianpeng offers a vast range of machines and testing equipment for cement and mortar that meets the requirements prescribed by the main industry Standards, with various models designed to suit all budgets. |
