Experimental Research on Temperature-Stress of Inorganic Polymer Concrete

Abstract

The inorganic polymer concrete is a new environmentally material. Using the temperature - stress test machine to research its early cracking sensitivity, and compare it with the normal concrete. The deformation development process of inorganic polymer concrete consists three stages:early contraction, expansion, contraction to cracking; cracking temperature can effectively evaluate the overall cracking performance of concrete; the cracking temperature of inorganic polymer concrete is 14.2 °C, the normal concrete is 14.4 °C; the inorganic polymer concretes cracking stress is 2.658MPa, the normal concrete is 0.582MPa. The results show the inorganic polymers cracking performance is better than the normal concrete.
