Quick repairing polymer cement base material and its preparing method

Abstract

The present invention is one polymer and cement-base quick repairing material for water engineering and building engineering. The material consists of portland cement, high-alumina cement, re-dispersed latex powder, high efficiency water reducing adhesive, sodium carbonate and other material in certain proportion. The material has high adhering strength and wide construction adaptability, and is suitable for construction in damp base especially.

Description

technical field

[0001] The invention relates to a polymer cement-based rapid repair material for hydraulic engineering and construction engineering and a preparation method thereof. Specifically, it relates to a powdery high-performance polymer cement-based rapid repair material with the functions of repair, reinforcement and anti-seepage in hydraulic engineering, construction, bridges, tunnels and other projects and its preparation. Background technique

[0002] Due to its high brittleness, concrete structures often crack inevitably in engineering applications. Cracking of the concrete structure leads to the decrease of water tightness and leakage of the concrete structure, which affects the service life of the project and even cannot be used normally. This is a common problem in the construction industry. There are two main reasons for cracks in concrete structures. One is caused by deformation, including temperature and humidity changes, shrinkage, expansion, uneven sub...
