EFFECT OF FIBER CLUSTERING EFFECT ON THE TENSILE PROPERTIES OF FIBER REINFORCED CONCRETE
摘要
Abstract
The fiber sharing coefficient is introduced to characterize the fiber clustering effect in concrete.Meanwhile,six kinds of fiber cluster model are established.According to mechanics theory of composite materials,the influence of fiber clustering effect on the tensile properties of fiber reinforced concrete (FRC) is analyzed.The results show that fiber share coefficient is decreased with the increase of fiber number of fiber agglomerates.The existence of fiber clustering effect leads to the increase of the fiber critical volume fraction to a certain degree and the decrease of the tensile strength of FRC in different degrees.The loss of FRC tensile strength by and critical volume fraction are increased with the increase of fiber cluster content.The calculated values of FRC tensile strength by considering fiber clustering effect are close to the experimental results.关键词
