【Abstract】 In this paper, compressive strength, flexural strength and strength at fracture initiation of polypropylene fiber net reinforced concrete with various mixing proportion are researched. Experiment indicates that brittleness of concrete can be fell and bending strength,strength at fracture initiation,failure strength of concrete can be increased evidently by mixing polypropylene fiber net into concrete.更多还原
