The article summarizes the study of the polypropylene fibers(PPF) and waste tire rubber powder modified concrete. By changing the amount of polypropylene fiber, the flexural strength , compression strength and apparent density of rubberized concrete with PPF at different ages were tested. The results show that the strength of rubberized concrete decreased, bu the flexural strength of concrete with PPF was improved significantly.
