  • Are You Mining Minerals for Cement, or for

    You can think of cement as the "glue" that holds the sand and gravel and re-bar (reinforcement bar) together to make concrete. Cement manufacturers mine and process raw materials and put them through a chemical reaction process to create cement. They need to understand the chemical composition of the raw materials so that the reaction in their process takes place correctly and they

  • Cement - Extraction and processing | Britannica

    Cement - Cement - Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.

    30.01.2014· If you want to get a little more technical, some concrete experts recommend going for 26 percent sand, 41 percent gravel, 11 percent cement and 16 percent water. The lacking 6 percent volume is air entrainment. Air entrainment is an admixture added to the mix during production to assist the mix in resisting the damaging effects of freeze-thaw cycles. This admixture is required in all concrete

    Cement Manufacturing Process. Cement is a material which is used to bind other materials together. Binding means it has an effect of gluing the substances together due to cohesive and adhesive action and then hardens and sets in order to become permanent. Cement is usually not used on its own; it is mixed with other materials called aggregates to produce a combined material of desired
