超高性能混凝土的材料性能

Material performance of Ultra-high Performance Concrete

相比于普通混凝土,超高性能混凝土具有高强度及优良耐久性的优势。但是由于超高性能混凝土对材料和制备工艺的要求较高,以及目前的理论并不成熟等原因,致使超高性能混凝土的推广速度较慢。根据现有的文献,对超高性能混凝土的抗压强度、抗拉强度、轴压应力—应变曲线和耐久性等材料性能进行了总结归纳,并对其研究方向进行了分析。

Compared with ordinary concrete,Ultra-high Performance Concrete has higher strength and more excellent durability. However,the Ultra-high Performance Concrete has higher requirement on material and preparation technology and immature theory,which leads to the promotion speed of Ultra-high Performance Concrete is slow. According to the existing literature,this article summarized the compressive strength,tensile strength,axial compression stress-strain curve and durability of Ultra-high Performance Concrete and analyzed its research direction.
