Anticracking waterproof agent

Abstract

The invention discloses an anti-cracking waterproofing agent, which is made of anhydrous gypsum, aluminum ore powder, lime, naphthalene-based water reducer, magnesium stearate, calcium gluconate, sodium tripolyphosphate, migratory rust inhibitor, formazan Prepared from base cellulose and triterpene saponin powder. The anti-cracking and waterproofing agent can greatly improve the workability and compactness of concrete, prevent concrete from cracking, greatly improve the anti-leakage and anti-rust functions of concrete, and meanwhile greatly improve the durability of concrete.

Description

technical field [0001] The invention relates to auxiliary materials for building materials, in particular to an anti-cracking and water-repellent agent used in concrete materials. Background technique [0002] With the development of the construction industry, the use of concrete, the main material in the construction industry, is gradually increasing, and people's requirements for concrete are getting higher and higher. Concrete is developing in the direction of high performance and high strength. Concrete water glue The ratio is getting smaller and smaller, while the amount of cementitious material and sand ratio are getting bigger and bigger. As a heterogeneous brittle material, concrete will expand with heat and contract with cold and shrink with moisture, especially when the water-cement ratio is low. This phenomenon is more obvious, and the factors that lead to concrete shrinkage increase. After the concrete is solidified, cracks are prone to occur, resulting in leakag...

Problems solved by technology

However, most of these additives not only have a single function, but also have poor anti-crack and anti-seepage effects, and their slump is small, which makes it difficult to pump and construct, which easily causes cracks and leakage in the concrete.
