Paper Title:
Splitting Strength of Hybrid Fiber Reinforced Concrete after Exposure to Elevated Temperatures
  Abstract

Experiments were carried out to investigate the splitting properties of hybrid fiber reinforced concrete after exposure to elevated temperatures. Based on the experimental observation, the effect of steel fiber dosage, polypropylene (PP) fiber dosage and strength grade of concrete on the residual splitting strength of the concrete after being subjected to high temperature was systematically analyzed. Test data indicated that high temperature caused significant deterioration in the splitting strength of concrete; the addition of PP fiber and steel fiber could all effectively improve the residual splitting properties of concrete; the optimum amount of PP fiber and steel fiber were identified respectively; the degree of strength loss of concrete with different strength grades was very close to each other. A theoretical equation was proposed to predict the residual splitting strength of concrete after being heated to temperatures up to 800°C.
