【Abstract】 The technical way of composing the polypropylene fibermesh with high strength concrete prepared by adding silica fume was applied to investigate the relationships between the mass content of silica fume and the effects of polypropylene fibermesh on strengthening, coefficient of brittleness, impact resistance and abrasion resistance of high strength polypropylene fibermesh concrete. The mechanism of enhancing the properties of high strength polypropylene fibermesh road concrete composite was discussed and analyzed. Results showed that the incorporation of silica fume in polypropylene fibermesh reinforced concrete composites can significantly increase the properties of road concrete materials.更多还原
