Test and Analysis of High Temperature Cooling Performance of High Strength Reinforced Concrete for Bridge
In order to analyze the performance changes of C80 high strength reinforced concrete specimens after high temperature treat-ment by natural cooling and water cooling,based on the theory and the related equipment,the high temperature simulation test is car-ried out,and the corresponding changes of compressive strength and splitting tensile strength are analyzed,the compressive strength of the concrete specimens with large cross-section size decreases with the increase of the temperature,and the compressive strength of the concrete specimens with different sizes decreases with the increase of the temperature,after natural cooling,the splitting tensile strength of concrete specimens decreases with the increase of temperature,especially for the specimens with large section size.With the increase of temperature,the splitting tensile strength of concrete specimens with different sizes decreases,and the strength loss of con-crete with large cross-section is greater.
