Composite cracking and seepage resistant agent and production process thereof

Abstract

The invention relates to a composite admixture applied to concrete and a production process thereof. The composite admixture is compounded by polypropylene fiber, expansion agent, waterproof agent, surfactant, water reducing agent and auxiliary material which serve as main components. The composite admixture can remarkably improve the cracking and seepage resisting effects of the concrete.

Description

technical field [0001] The invention relates to a composite admixture applied to concrete and a production process thereof, in particular to a composite anti-crack and anti-seepage agent and a production process thereof. Background technique [0002] The brittleness of concrete products in the hardening and shrinking stages is destined to have certain defects in its own working state. Due to the shrinkage, settlement and hydration process, a large number of cracks will be generated, which seriously affects the quality of concrete. In practical applications There are often problems such as cracking and leakage. The civil engineering field has gone through long-term research on how to solve the problem of leakage and seepage prevention. As a method to solve the above problems, admixtures are widely used. With the development of concrete towards light weight and high performance, traditional single concrete admixture products can no longer fully realize the optimization of con...
