摘要
完成了再生砂浆高温后的单轴受压试验,研究了取代率、温度对再生砂浆抗压强度、破坏形态、弹性模量的影响。研究结果表明,再生砂浆的受压强度、弹性模量随着温度的不断升高而不断降低;再生砂浆试件随着温度的升高而呈现不同颜色。
The uniaxial compression experiment was conducted on recycled mortar after high temperature.The effect of the recycled fine aggregates content and temperature on the compressive strength, failure mode and elastic modulus of recycled mortar were studied.The re- sults show that the compressive strength and elastic modulus of recycled mortar are decreased with the increase of temperature, and the colour of recycled mortar is different with the increase of temperature.
