Study on the Durability of Hydration Controlled Concrete Admixtures

By designing the concrete mix ratio of the hydrationregulating polycarboxylic acid admixture, and adjusting a series of parameters such as the strength grade of the mixture, the water-cement ratio, the type and quantity of admixture, the influence of various parameters on the working performance and durability of concrete was studied. The results show that the hydration controlled polycarboxylic acid admixture can greatly improve the workability, impermeability and freeze-thaw resistance performance of concrete.
