Anlysis on Freeze-Thaw Cycling Damage of Layered Hybrid Fiber Reinforced Concrete


Article Preview

Based on the least squares theory and a damage variable , a damage model is formed for the freeze-thaw degradation of the layered hybrid fiber reinforced concrete (LHFRC). By the model the degradation equations for the LHFRC and the plain concrete(PC) are regressed with the experimental data, which are identical in the initial phase and different in the damage propagation phase and the is used to describe the damage process of concrete subjected to freeze-thaw cycles. The of LHFRC is smaller than that of PC in the damage propagation phase. Furthermore, the frost resistance of LHFRC is stronger than that of PC due to steel fibers and polypropylene fibers having retarded the degradation of concrete.
