Abstract: Cementitious coefficient beta(t) was introduced to reflect the comprehensive effect of fly-ash quality on HFCC strength. On the basis of beta(t), actual water-binder ratio [W/(C+beta F-t)] and ash-binder ratio K was proposed, and the strength calculation model of HFCC with specific design age was established. On the basis of economy principal, the formula to determine K was founded. Influence of the design strength of HFCC and beta(t) on K and the content of fly ash was analyzed.
