Cement is a fine mineral powder manufactured with very precise processes. Mixed with water, this powder transforms into a paste that binds and hardens when submerged in water. Because, the composition and fineness of the powder may vary, cement has different properties depending upon its makeup. Cement is the main component of concrete and mortar. It is an economical, high-quality construction material used in construction projects worldwide.
Testing of cement is essential as the life of structure is dependent on the quality of material used. Following are the tests to be conducted to judge the quality of cement.
The Cement laboratory provides all the state of the art facilities for testing the strength and other basic properties of cement as well as Steel Reinforcement and Bricks.
