Description
Technical Field

Background
With the progress of society and the improvement of living standard of people, the requirements of people on the quality and the functions of modern building materials are higher and higher, and especially the cracking resistance, the waterproof performance and the durability of concrete are higher and higher. Cracking of concrete is mainly caused by the following reasons: 1. cracking and water seepage phenomena caused by deformation due to temperature shrinkage and drying shrinkage in the hydration hardening process of the concrete can seriously influence the durability of the concrete; 2. fine air holes are uniformly distributed in the formed concrete, and the concrete can have water seepage phenomenon due to hydrostatic pressure and capillary action, so that water seepage can be greatly influenced on the concrete and mortar and even building structures. Therefore, the waterproof effect has an important influence on engineering quality, and solving the problems of cracking and water seepage is one of important directions for people to study concrete.
At present, the performance of concrete is improved mainly by adding an anti-cracking waterproof additive, and the waterproof agent can be divided into an inorganic waterproof agent, an organic waterproof agent and an inorganic-organic composite concrete waterproof agent according to chemical components. The inorganic waterproofing agent mainly reduces the pores in concrete by inorganic compounds (such as chloride salts of iron or aluminum) and improves the compactness and the impermeability. The organic waterproof agent mainly forms a hydrophobic surface on the surface of concrete through organic compounds (such as stearic acid) and improves the impermeability. The inorganic-organic composite concrete waterproof agent is an inorganic-organic composite system and has the functions of waterproof, plasticizing and the like.
The existing anti-cracking waterproof additive is single in general effect and poor in waterproof and anti-cracking performance, so that an additive capable of better improving the anti-cracking and waterproof performance of concrete is needed.
