Working Performance Control Technology of Underwater Grouting Pile Concrete
Abstract
As an important part of concrete, the improvement effect of admixture on the performance of concrete has been paid more and more attention. In this paper, the effect of the compounding ratio of polycarboxylate liquor with different functions on the dosage sensitivity and slump retention of the admixture was studied. Foam control technology was used to improve the viscosity of concrete which was in favor of the fillability of concrete. In addition, the optimal formulation of proprietary admixture was determined by compressive strength test.
