Study on the Shear Strength of HMPE Fiber Reinforced Concrete

Concrete as a most popular construction material has many advantages such as easiness to be formed into various shapes, common availability and relative low cost. However, the low strength in both tension and shear is limited for the wider application of the material. In this study, an advanced material of high strength and strong abrasion resistance HMPE fiber was used to reinforce concrete properties. A series of experimental testing were carried out to examine the properties of both fresh and hardened HMPE fiber reinforced concrete. It was found that the addition of an HMPE fiber material in concrete may enhance its shear strength as high as 30% increment. Corresponding to the increase of length of fiber entrained in the concrete, a slightly decreasing trend in shear strength was observed.
