Using microwave heating method to establish a set of effective technology about uniaxial compression test of concrete, and obtain the experiment phenomenon of concrete when the temperature is 16 -650 . Experiment results indicate that when concrete is damaged by high temperature, the strength of concrete decreases, the peak strain increases, and the elastic modulus decreases. Based on test data, a unified equation was putted forward to describe the relation between concrete compressive strength, the peak strain, elastic modulus and temperature. While, obtain concrete temperature stress and strain curve, and analysis shows that it gradually becomes compressed with the increase of temperature, peak point falls and moves right obviously.
