Mix Proportion Design of P (AA-co-MA)/PEG Polycarboxylic Copolymer and High Performance Concrete with Composite Admixture

This paper sets forth from the effect analysis of the concrete raw materials and all kinds of the performance index tests. It makes further research and exploration of the mix proportion design of P (AA-co-MA)/PEG polycarboxylic copolymer and high performance concrete with composite admixture, combining the mixture of the high performance concrete as well as the performances such as the workability, the hardness of the cement setting and hardening and the endurance quality. It is found that mixing 1.46% P (AA-co-MA)/PEG polycarboxylic copolymer, 15% fly ash and 10% granulated blast furnace slag powder together and adding the mixture into the concrete can not only save the cement but also improve the performance of the concrete. The designed C30 mix propor-tion design of P (AA-co-MA)/PEG polycarboxylic copolymer and high performance concrete with composite admixture has been applied successfully in the high-rise building construction.
