| Abstract: | 16 groups mix proportion scheme were designed to investigate the influence of water-binder ratio and fly ash replacement on recycled coarse aggregate concrete compressive strength. Relationship among water-bind ratio, fly ash replacement and compressive strength were found, and bivariate strength formulas were obtained by means of dualistic linear and non-linear regression. |
