Alloy powder concrete waterproofing agent and preparation method thereof
The invention provides an alloy powder concrete waterproofing agent. The alloy powder concrete waterproofing agent is characterized by being prepared from the following materials in percentage by mass: 79-94% of an aluminum oxide alloy compound, 5-20% of a magnesium oxide alloy compound, 0.2-0.4% of benzoates, 0.2-0.4% of alkylol amines, 0-0.1% of alkyl sodium sulfonate and 0.1-0.2% of nano-silicon dioxide. The alloy powder concrete waterproofing agent has the advantages that by virtue of the functions of reducing water, adsorbing, diffusing and introducing air, the structural distribution of internal holes in concrete is changed and the porosity is remarkably reduced, so that sealed bubbles can be generated in the concrete, and the bleeding rate can be reduced; meanwhile, the internal holes in the concrete are filled, so that the anti-penetrability performance of the concrete in the later period can be greatly improved.
