摘 要:对素混凝土板、钢板网混凝土板、纤维织物网混凝土板及纤维织物与钢板网联合增强混凝土板的四点弯曲性能进行了试验对比分析。试验结果表明,钢板网、纤维织物网以及纤维织物网与钢板网联合增强混凝土板的抗弯性能,较素混凝土板,分别提高了5.6%、21.1%和42.1%。纤维织物网和钢板网可以有效提高混凝土板的变形能力,而且织物网的加入可以改善钢板网与水泥基复合材料之间的黏结性能。
Abstract:The four-point bending tests are carried out, and the bending properties of the concrete plates, expanded steel concrete, textile reinforced concrete enforced by both textile and expanded steel are compared and analyzed. The results show that bending properties of the concrete plates, expanded steel concrete and textile reinforced concrete are better than that of the concrete plate, and respectively improve 5.6%, 21.1% and 42.1%. The numbers show the fabric mesh and steel mesh can improve the deformation capacity of concrete plates. And the fabric mesh can improve the bond performance between steel mesh and cement based composite materials.
