Problems solved by technology

At present, waterproof materials are usually used to solve the water leakage problem of concrete structures. For example, the Chinese patent with the publication number CN107010863A discloses a concrete waterproof agent, which is composed of illite powder, fly ash, alum, slaked lime and superphosphate. Although the agent can improve the water resistance of concrete to a certain extent, its function is relatively single, and it cannot cover the waterproof performance and construction requirements of various types of concrete, and cannot be applied to situations such as serious water leakage in buildings.

Abstract

The invention provides a concrete structure self-compacting waterproofing agent and a preparation method and application thereof. The concrete structure self-compacting waterproofing agent comprises the following components in parts by mass: 16-19 parts of alkyl silicate, 15-18 parts of fluosilicate, 3-7 parts of a dispersing agent, 2-4 parts of molten aluminum, 4-7 parts of a water reducing agentand 2-5 parts of a slump retaining agent. The concrete structure self-compacting waterproofing agent has the functions of crack resistance, water reduction, water retention, delayed coagulation, porosity, microcrack self-healing and the like, can further improve the comprehensive properties of the concrete structure, such as strength, impermeability, durability and the like, and is beneficial toprolonging the service life of the concrete structure.

Description

technical field [0001] The invention relates to a waterproofing agent, in particular to a concrete structure self-compacting waterproofing agent and its preparation method and application. Background technique [0002] In my country's buildings, underground shopping malls, underground equipment and office buildings, subways, tunnels, caverns, pipe galleries, underground pedestrian passages, civil air defense, military facilities, water purification plants, sewage treatment plants, swimming pools, and water conservancy projects , Energy storage power stations, highways, high-speed railways, bridges and other projects have more common water leakage problems, and the cost of plugging and maintenance is relatively high. Leakage of underground engineering causes corrosion of structural steel bars, a substantial decrease in steel strength, expansion and damage of concrete, and a greatly reduced service life, which not only causes serious national property and economic losses, but a...
