Sentences with phrase «cement production»
"Cement production" refers to the process of making cement, a material used in construction. It involves mixing various ingredients, such as limestone, clay, and other minerals, with water to form a paste. This paste is then heated in a kiln to create a solid substance called clinker, which is crushed into a fine powder. This powder, when mixed with water, sand, and gravel, forms concrete, which is used to build structures like buildings, bridges, and roads. Full definition
