Abstract

The invention provides a concrete synergist and a preparation method thereof. The concrete synergist comprises polyacrylamide, sodium sulfite, polyol, triisopropanolamine, calcium formate, diethylenetriamine pentacarboxylic acid sodium, sodium hexametaphosphate and the rest water. According to the concrete synergist, the dispersity of cement particles is efficiently stimulated, cement hydration rate is promoted, and cement is more sufficiently hydrated. Powder filling of cement components is reduced, the usage of the cement components can be effectively reduced without changing the comprehensive performance of concrete, and concrete cost is greatly reduced. Moreover, by cooperation of the components of the concrete synergist, the early and later strength of the concrete can be improved, and the overall comprehensive performance of the concrete can be greatly improved. The production process is simple, free from pollutant emission and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of concrete admixtures, in particular to a concrete synergist and a preparation method thereof. Background technique [0002] Concrete is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, which is widely used in civil engineering. Concrete is widely used as a building material, and so far there is no foreseeable material that can replace the application of concrete. [0003] Cement is the most expensive of the components to produce concrete. Cement is a powdery hydraulic inorganic gelling material. After adding water and stirring, it becomes a slurry, which can be hardened in...
