Description

technical field [0001] The invention relates to a preparation method of a cement reinforcing agent, which belongs to the field of building material manufacturing. Background technique [0002] As we all know, cement is one of the main products of building cementitious materials. Cement is silicate clinker made by mixing limestone, coal, iron powder and clay and other mineral raw materials, and then adding gypsum to the clinker and grinding finely made. With the rapid development of my country's economy, the amount of cement is increasing exponentially. Therefore, the consumption of mineral raw materials such as limestone, coal, iron powder and clay is increasing day by day, and mineral resources are continuously decreasing. At present, under the premise of ensuring the strength of cement, cement manufacturers use technical means to properly mix some mixed materials to achieve the purpose of saving mineral resources, reducing cement costs and protecting the environment. Amon...
