Capillary crystalline patch plaster

Abstract

The invention discloses a capillary crystalline patch plaster which comprises the following components in parts by weight: 30-60 parts of ordinary portland cement, 30-70 parts of sulphate aluminum cement, 10-30 parts of sand, 1-4 parts of capillary crystalline materials, 0-0.2 part of water-reducing agents, 1-4 parts of rubber powder, 0-0.3 part of water retention agents and 0.1-0.3 part of anti-crack fibers. The capillary crystalline patch plaster disclosed by the invention has the advantages of high early strength, excellent bonding property, excellent anti-crack property, very good restoration function on microcracks, convenience for construction and environment friendliness without toxicity.

Description

Technical field [0001] The invention belongs to the technical field of building materials, and specifically relates to a permeable crystal repair mortar. Background technique [0002] With the continuous improvement of people’s living standards and living conditions, the importance of household waterproofing has become increasingly prominent. In family life, the kitchen and bathroom are the key areas that need to be waterproofed. However, due to leakage of the kitchen bathroom floor and external walls, dampness and mold have become A common problem in current housing quality. Due to the small area of ​​the kitchen and bathroom, and the extremely irregular vertical planes, and the large number of buried pipes, not only the overall waterproofing of the horizontal plane, but also the waterproofing of the vertical surface of the conduit is required, which makes the entire waterproofing construction difficult. Therefore, it is very important to use repair mortar to repair the base su...

AI Technical Summary

Problems solved by technology

[0003] At present, ordinary cement mortar is mostly used for kitchen and bathroom repairs. Because cement-based materials have good compatibility with concrete bases and are cost-effective, they are widely used, but there are still some shortcomings, such as low early strength, which leads to long construction period; bonding Poor performance. After construction, the bonding between the repair material and the concrete foundation interface is weak, and it is prone to hollowing and peeling, which affects the performance of the waterproof layer. Poor crack resistance, shrinkage after construction cannot be effectively controlled, resulting in repair failure
