Mechanical Properties Analysis of Super Early-Strength Composite Fiber Concrete after High Temperature

Experimental method is applied to analysis the mechanical properties of super early-strength composite fiber concrete on high temperature. Specimen are heated to in the stove at different temperatures for 30 Minutes, then the axial compressive strength can be measured. The experimental results showed that: the high temperature mechanical properties of materials decreased significantly; compared to ordinary concrete specimen, the mechanical properties of super early-strength composite fiber concrete decline slower.
