加速老化环境下E玻纤织物增强硅酸盐水泥基薄板拉伸性能试验研究
|
摘要
本文通过试验研究了加速老化环境下E玻纤织物网增强的硅酸盐水泥基混凝土薄板的拉伸力学性能,得出结论:在硅酸盐水泥薄板中铺设E玻纤织物网,在一定时间范围内,对薄板的抗拉强度具有较好的增强效果,可以用于临时结构,或短期利用E玻纤织物网增强效果的结构。
In this paper, the tensile mechanical properties of Portland cement-based concrete sheet reinforced by E-glass fabrics under accelerated aging conditions were studied experimentally, The results show that laying the E-glass fabric in the Portland cement sheet has a better strengthening effect on the tensile strength of the sheet in a certain time, the sheet can be used for temporary structures, or for the structure that use the E-glass fabric to increase it's strength in short-term.
