【Abstract】 In this paper, two kinds of polypropylene fibers were treated with the surface adopted chemical methods. The resistance to cracking, the mechanical properties of fibers-reinforced high performance concrete and the workability of its mixture were also investigated. Results showed that chemical treatment methods could improve the combinability of fibers and concrete, low mixing amount synthetic fibers had obvious resistance to the cracking of early high performance concrete.更多还原
