摘要：
Polypropylene fiber with different use level were added in concrete for road pavement. The change of slump, compressive strength, flexural strength and shrinkage were determined. The results indicate that concrete slump decreases as the use level of polypropylene fiber increases. The 28 d compressive strength of concrete with polypropylene fiber use level of 1.0, 1.5, 2.0 kg/m3 increases by 4.1%, 17.0% and 6.9% respectively compared with that of plain concrete, 28 d flexural strength increases by 11.4%, 24.3% and 26.1% respectively, and 28 d shrinkage decreases by 16.0%, 20.9% and 29.8% respectively compared with that of plain concrete.
