This article investigates the effects of AR glass fibers and micronized natural zeolite on reducing permeability and increasing compressive strength. However, there is little detailed information about the impact of the interaction of zeolite and AR glass fibers on the mechanical properties and their comparison in normal environments with Chloride (NaCl) and sulfate (MgSO4). According to the results of the tests, the compressive strength of mixture 9 (1 % by volume of concrete, glass fibers, and 12 % by weight of cement, zeolite) and mixture 11 (2 % by volume of concrete, glass fibers, and 8 % by weight of cement, zeolite) in normal environments, Chloride and sulfate increased by 43.2, 34.8, and 30.1, 64.1, 68, and 58.8 %, respectively, compared to the control sample of its environment. The permeability of mixtures 9 and 11 has decreased by 68.42, 66.67, 42.31, 47.37, 61.9, and 55.77 %, respectively, compared to the control sample of its environment. Finally, SEM images have been used to investigate the microscopic structure.

AR 玻璃纤维和天然微粉化沸石对暴露于正常、氯化钠和硫酸镁环境中的混凝土力学和渗透性能的影响



本文研究了 AR 玻璃纤维和微粉化天然沸石对降低渗透率和提高抗压强度的影响。然而,关于沸石和 AR 玻璃纤维相互作用对机械性能的影响以及它们在正常环境中与氯化物 (NaCl) 和硫酸盐 (MgSO4) 的比较的详细信息很少。根据测试结果,混合物 9(混凝土、玻璃纤维体积的 1%,水泥、沸石重量的 12%)和混合物 11(混凝土、玻璃纤维体积的 2%,水泥、沸石重量的 8%)的抗压强度在正常环境中,氯化物和硫酸盐增加了 43.2、34.8 和 30.1, 64.1 、 68 和 58.8 %。与环境对照样品相比,混合物 9 和 11 的渗透性分别降低了 68.42、66.67、42.31、47.37、61.9 和 55.77 %。最后,SEM 图像已被用于研究微观结构。
