Abstract

The invention discloses a preparation method of a cement enhancer capable of improving the strength of a cement product. The preparation method is characterized in that the cement enhancer is prepared from the following raw materials: dickite, montmorillonite, shale, calcite, diatomaceous earth, calcium fluoride, mirabilite, polyvinyl alcohol, sodium acetate, sodium carbonate, gypsum, sodium silicate, aluminum powder and calcium nitrate. The raw materials of the enhancer are easy to buy, the production process is uncomplicated, simple and easy for product production, and the cement enhancer is convenient and uniform to use, and the stability in production can be satisfied; moreover, the production efficiency can be improved, and the cost can be saved.

Description

technical field [0001] The invention relates to a method for preparing a cement reinforcing agent, that is, a method for preparing a cement reinforcing agent capable of improving the strength of cement products, and 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 ...
