| Abstract: | The relationships among the strength, contraction, fatigue deformation, the proportion of the mixture and aggregate rate of lime-flyash concrete were analyzed through theoretical analysis combining with indoor experiments and engineering practice. Some corresponding considerations during design were presented in the paper. |
