Technical Field

The invention relates to the field of curing materials, in particular to a solidification additive, a preparation method and application thereof.

Background

Concrete is generally formed by mixing cement, sand and crushed stone (or gravel) with water. Such concrete is mainly used as a building structural material or a paving material, etc. The use of a large amount of cement causes serious pollution to the environment, substances polluting soil and water sources are generated along with the interaction of components in the cement, for example, various hydrates are generated due to hydration reaction, redundant calcium hydroxide overflows to pollute the surrounding soil and water, the existing cement cannot meet certain high-strength construction requirements, and if the basic amount of cement cannot meet the strength requirement, the freezing effect in winter can be reduced to the maximum extent by increasing the cement consumption, and the deficiency of the strength is made up. However, excessive cement causes the above-mentioned environmental pollution problem.

Accordingly, the prior art is subject to further development and advancement.
