混杂纤维水泥基复合材料强度试验研究

EXPERIMENTAL STUDY ON THE INTENSITY OF HYBRID FIBER REINFORCED CEMENT BASED COMPOSITE MATERIAL

研究了是掺有微钢纤维和PVA的混杂纤维对水泥基复合材料强度的影响。试验设置三组不同纤维体积的混杂比为1:1、1:3、1:2,来配制纤维增强水泥复合材料。研究不同纤维体积混杂比下,轴心抗压强度与立方体抗压强度的关系。结果表明:不同纤维体积混杂比情况下,轴心抗压强度和立方体抗压强度成线性关系。

The research of this paper is the effect of hybrid fiber mixed with micro steel fiber and PVA on the performance of cement-based composite materials. The test set three hybrid ratio of different fiber volume,which are 1： 1,1： 3,1： 2,to optimize the cement composite material. Under different mixed fiber volume ratio,the relationship of axial compressive strength and cubic compressive strength is researched. The results show that under the hybrid fiber,ratio axial compressive strength is linear with cubic compressive strength.
