摘　　要：为了研究碳-聚丙烯纤维混凝土力学性能,以及碳纤维和聚丙烯纤维对混凝土强度的影响,本文进行了纤维混凝土的力学试验研究。基于抗压强度为C40的普通混凝土的配合比,本文设计了纤维混凝土的配合比。通过立方体抗压和劈裂抗拉试验得到混凝土的抗压强度和抗拉强度,试验结果表明:碳纤维掺量在一定范围内可以增加混凝土的抗压、抗拉强度;而聚丙烯纤维的掺入对混凝土的抗压强度仅有降低作用,对抗拉强度的影响较为复杂;纤维总体积掺量与混凝土的拉压比呈正相关关系。In order to study the compressive property,tensile property and the effect of the carbon fiber and polypropylene fiber on the concrete,in the paper the mechanical properties researches are carried out.Based on the ordinary C40 concrete mix ratio,the fiber concrete proportioning is designed.The compressive strength and tensile strength are obtained by the cube compressive and splitting tensile test.The research shows that the compressive and tensile strength of concrete can be enhanced to a certain extent with the addition of carbon fiber;however polypropylene fiber only can reduce the compressive strength of concrete and has a complex effect on tensile strength;and the total content of fiber is positively correlated with the tensile/compressive ratio of concrete.
