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.

Embodiment 1

[0020] The percentage by weight is 39% of anhydrite, 37% of aluminum ore powder, 7% of lime, 10% of FDN-A, 3% of magnesium stearate, 1.4% of calcium gluconate, 2.0% of sodium tripolyphosphate, migration type 0.4% of rust inhibitor, 0.03% of methyl cellulose, and 0.1% of triterpenoid saponin powder are mixed uniformly in the sample mixing machine, and then transported to the ball mill through the belt conveyor to be ground into a powder of specified fineness, and then transported to the homogenization warehouse After homogenization, it is made into powdery anti-cracking and waterproofing agent.

Embodiment 2

[0022] The percentage by weight is 36% of anhydrous gypsum, 33% of aluminum ore powder, 10% of lime, 13% of FDN-A, 2% of magnesium stearate, 1.5% of calcium gluconate, 1.6% of sodium tripolyphosphate, and migration type retarder. 0.7% of rust agent, 0.05% of methyl cellulose, and 0.2% of triterpenoid saponin powder are mixed uniformly in the sample mixing machine, and then transported to the ball mill through the belt conveyor to be ground into a powder of specified fineness, and then transported to the homogenization warehouse for further processing. After homogenization, it is made into powdery anti-cracking and waterproofing agent.

Abstract

The present invention discloses one kind of anticracking waterproof agent, which is prepared with anhydrite, aluminum ore powder, lime, naphthalene water reducing agent, magnesium stearate, calcium glyconate, sodium tripolyphosphate, migrating antirust agent, methyl cellulose and triterpenoid saponin powder. The anticracking waterproof agent can raise the compactibility, antiseep function, antirust function and durability of concrete greatly.

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...
