Alkali-activated mixtures are advantageous materials, being more sustainable and environmentally friendly as they do not contain cement. In this study, ground granulated blast-furnace slag was activated with sodium hydroxide solution and liquid sodium silicate. The use of ground waste glass as a source of silicate instead of sodium silicate was investigated. For this purpose, mortar specimens with sodium hydroxide content in different molarities were produced by replacing sodium silicate with ground waste glass. The mechanical and durability properties of the mixtures were examined under three different curing conditions: moist curing, air curing and air curing after 24 h at 60°C. The compressive and flexural strengths of the specimens were determined at the ages of 3, 7, 28 and 90 days. Capillary suction, water absorption, rapid chloride penetration, electrical resistivity, freeze–thaw and sulfate resistance tests were also performed. In consequence, it was found that waste glass can be used as an alternative silicate source in alkali-activated mortars.

废玻璃在碱活化矿渣砂浆中作为活化剂的应用

碱活化混合物是一种有利的材料，由于不含水泥，因此更具可持续性和环保性。在这项研究中，用氢氧化钠溶液和液体硅酸钠活化磨碎的粒状高炉矿渣。研究了使用磨碎的废玻璃代替硅酸钠作为硅酸盐的来源。为此，通过用磨碎的废玻璃代替硅酸钠来生产具有不同摩尔浓度的氢氧化钠含量的砂浆试样。在三种不同的固化条件下检查了混合物的机械和耐久性性能：湿固化、空气固化和 60°C 下 24 小时后的空气固化。在 3、7、28 和 90 天时测定试样的压缩和弯曲强度。毛细管吸水、吸水、还进行了快速氯化物渗透、电阻率、冻融和耐硫酸盐测试。结果，发现废玻璃可用作碱活化砂浆中的替代硅酸盐来源。
