Preparation method of waterproof concrete
Provided is a preparation method of a waterproof concrete; raw material components comprising cement, sand, carpolite, water, a water reducing agent, a swelling agent and fly ash are stirred and mixed and cured to obtain the waterproof concrete; the swelling agent allows the concrete to swell in a constrained environment, communication holes in the concrete are significantly reduced, the anti-permeability waterproof properties are enhanced, and the strength is also increased significantly; with addition of the water reducing agent, the stability and performance of the concrete are enhanced, problems of common dissociation and water segregation and collapsed slump loss of large-liquidity pumped concrete are avoided, a non-vibrating self-compacting effect is achieved, and construction is convenient; with the use of the fly ash, concrete pores and capillary pores are filled, and with the addition of the fly ash, a pore structure of the concrete is improved and the compactness is increased; and the prepared waterproof concrete is good in self-compacting performance and excellent in anti-permeability and anti-crack performance, and has the later strength improved significantly.
