摘　　要：本文以天津地区某混凝土塔筒工程实例为依托,对C80截锥状塔筒用混凝土的配合比进行优化设计,研究水胶比和砂率对混凝土工作性能、力学性能及表观效果的影响。综合各项性能测试结果表明:当C80截锥状塔筒用混凝土的水胶比为0.22,砂率为32%时,混凝土的工作性能、力学性能较优,且能够满足工程实际需求,可为该类现场预制塔筒构件用高强高性能混凝土的配合比设计提供技术参考。Based on a concrete tower project in Tianjin,this article optimizes the mix proportion of concrete for C80 truncated cone tower,and studies the effects of water cement ratio and sand ratio on the working performance,mechanical properties,and apparent effect of concrete.The results show that when the water cement ratio of C80truncated cone tower concrete is 0.22 and the sand ratio is 32%,the working and mechanical properties of the concrete are superior,and it can meet the actual engineering needs.It provides a technical reference for the mix design of high strength and high performance concrete for on-site prefabricated tower components.
