Abstract: Steel (steel bar or steel fiber) reinforcement is an important approach to improve the performance of concrete. However, steel corrosion lead to the decrease of durability of concrete. Coarse polymer fiber (CPF) is a new type of reinforce material which was developed to replace the steel fiber (SF). In this paper, mechanical properties of four types of concrete (concrete without fiber, concrete containing CPF, concrete containing steel fiber, concrete containing hybrid fiber) was experimental investigated. Results reveal that CPF can improve the performance of concrete as well as SF. However, the reinforce effect of CPF are differ from the SF. Due to the low elastic, the CPF can keep the integrity after the penetrating cracks appear and the composites can bear additional load.
