摘　　要：在水利工程施工中,为防止开裂问题发生,对混凝土材料的要求较高。因此,通过不同的配合比试验,来加强混凝土的力学性能,并对WSP混凝土的力学性能、龄期以及抗弯强度之间的关系进行研究。结果表明:钢纤维混凝土以及聚丙烯纤维混凝土强度在7 d时,相比普通混凝土,强度有所提高,28 d时,对于混凝土影响比较大的是钢纤维。在7 d时,WSP改性混凝土强度降低了19.14%,28 d时,WSP混凝土后期强度有着明显的提升。在28 d时聚丙烯纤维以及钢纤维的轴心抗压强度作用最明显。对于混凝土抗折强度提升影响从小到大分别是:WSP改性钢纤维、WSP改性混凝土、聚丙烯纤维、钢纤维。In the construction of water conservancy projects,the requirements for concrete materials are high in order to prevent the occurrence of cracking.Therefore,the mechanical properties of concrete are strengthened through different mix ratio tests.And the relationship between the mechanical properties,age and bending strength of WSP concrete is studied.The results show that the strength of steel fiber reinforced concrete and polypropylene fiber reinforced concrete is higher than that of ordinary concrete at 7d and steel fiber had a greater impact on concrete at 28d.At 7d,the strength of WSP modified concrete decreased by 19.14%.At 28d,the post-strength of WSP concrete was significantly improved.At 28d,the axial compressive strength of polypropylene fiber and steel fiber was the most obvious.The impact on the flexural strength of concrete from small to large is arranged as WSP modified steel fiber,WSP modified concrete,polypropylene fiber,and steel fiber.
