Abstract：
With the mass construction application of C80 high strength concrete in Pearl River New Town. In this paper, according to the concrete mix design discipline, it scientifically calculated the mix proportion, so as to determine the benchmark mix proportion.This paper adopted“trinal mixing technology”,which includes two kinds of high performance mixing (slag powder and silica fume) and high efficiency water reducing agent. Through many experiments,we makes a facilitating high pumping and good workability(slump is between 180mm and 220mm,fluidity is more than 600mm) C80 high performance concrete, for the future of the design of similar mix proportion to provide the beneficial reference and using for reference.
