不同温度下混凝土补强的力学性能研究

Mechanical Property of Concrete Reinforcement under Different Temperatures

本研究主要探讨混凝土补强在不同温度下的力学性能;以普通混凝土添加不同钢纤维含量的活性粉混凝土为补强材料,进行高温试验项目包括:抗压强度、抗弯强度、抗拉强度、斜剪强度等试验。结果显示,添加钢纤维的活性粉混凝土在高温中,可以达到增加补强的作用。

The mechanical properties of concrete reinforcement in different temperatures are discussed.The RPC（ reactive powder concrete） with different steel fiber content is used as reinforcing material. The high temperature test items include compressive strength,bending strength,tensile strength,oblique shear strength and and so on. The results show that RPC can increase efficiently as the role of reinforcement in high temperature.
