摘要
在超高性能混凝土(UHPC)中添加粗骨料是为了在获得优异的力学性能基础上,大幅降低生产成本,使其更容易被市场采纳.本文对UHPC-CA配合比中浆骨比、砂率、粗骨料种类及减水剂品种等因素进行调整,通过不同龄期抗压强度对比以及微观角度分析,探索各因素对UHPC-CA力学性能的影响.
Abstract
Adding coarse aggregates to ultra-high performance concrete(UHPC)is to significantly reduce production costs and make it more easily accepted by the market while achieving better mechanical properties.This paper adjusts the factors such as slurry to bone ratio,sand ratio,coarse aggregate type,and water reducing agent type in the UHPC-CA mix proportion.By comparing the compressive strength at different ages,further analysis is conducted from a microscopic perspective to explore the influence of various factors on the mechanical properties of UHPC-CA.
