钢丝网水泥是由水泥砂浆、钢丝网和钢筋网合成的一种组合材料。因为水泥砂浆的拉和压存在着不同的弹性性能,钢丝网和钢筋网在不同方向有着不同的受力性能,所以钢丝网水泥具有各向异性的特点。从配有方格形钢丝网的构件沿网筋方向的拉、压应力(σ)—应变(ε)曲线图中可以看出,拉伸构件在开裂前的弹性模量(E_t)相同于受压构件屈服前的弹性模量(E_c),即 Wire mesh cement is a composite material composed of cement mortar, steel mesh and steel mesh. Because there are different elastic properties in the pulling and pressing of the cement mortar, the steel mesh and the steel mesh have different stress properties in different directions, so the wire mesh cement has anisotropic characteristics. From the graph of tensile and compressive stress (σ)-strain (ε) along the web direction of the member with grid-like wire mesh, it can be seen that the elastic modulus (E_t) of the tensile member prior to cracking is the same as The elastic modulus (E_c) before the compression member yields, ie
