Mix proportion design method for systematical high performance concrete

Based on the Mehta and Aitcin's high performance concrete mix proportion design method, by establishing the relationship between concrete strength and effective water binder ratio, coarse aggregate loose volume fraction and efficiency factor of fly ash as well, and the relationship between coarse aggregate loose volume fraction and sand ratio, thus the relationship among concrete constitutes such as coarse aggregate, fine aggregate, water content and cementitious materials was established. As a result, a systematical high performance concrete mix proportion design method was developed. This mix proportion design method makes concrete mix proportion design to be easier and more exact with enhanced fitness range and programmability. Experiments results show that using the systematical high performance concrete mix proportion design method can produce concrete with compressive strength cohere well with the expected one.
