Calculation Model of Compressive Strength of High Fly-AshContent Concrete at Specific Age

Abstract:

Article Preview

Cementitious coefficient βt was introduced to reflect the comprehensive effect of fly-ash quality on HFCC strength. On the basis of βt, actual water-binder ratio [W/(C+βtF)] 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 βt on K and the content of fly ash was analyzed.
