Description

Anti-cracking and anti-seepage agent for concrete and preparation method thereof Technical Field

[0001] The invention relates to the technical field of anti-seepage agent processing, in particular to an anti-cracking and anti-seepage agent for concrete and a preparation method thereof. Background Art

[0002] Concrete is one of the most important civil engineering materials in contemporary times and is widely used in all aspects of the construction field. However, concrete, especially large-volume concrete and high-strength concrete, is prone to shrinkage, which leads to concrete cracking and reduces the concrete's strength, anti-seepage, and corrosion resistance. The obvious drawbacks of using expansion agents as shrinkage-compensating concrete materials on the market are: the high hydration heat of concrete, large shrinkage deformation of concrete, widespread cracking and leakage of concrete, and a significant reduction in concrete strength. Moreover, the various types of concrete shrinkage-compensating materials in China, such as expansion agents, are mostly processed at high temperatures using pure raw materials, which not only causes huge energy consumption but also has varying degrees of impact on the environment. In addition, the production cost of the products is high, so the market selling price of such products is generally reduced by using anti-cracking and anti-seepage agents.

[0003] Anti-cracking and anti-seepage agent is a special chemical material used to treat the surface or interior of concrete to prevent concrete cracking and penetration problems. However, current anti-cracking and anti-seepage agents will have durability problems after long-term use and exposure environment, resulting in a decrease in anti-cracking and anti-seepage effects. Therefore, an anti-cracking and anti-seepage agent for concrete and a preparation method thereof are proposed.
