磨碎的粒状高炉矿渣是在高炉中作为副产品从熔融铁中分离的细磨的、快速冷却的铝硅酸盐熔体材料。快速冷却会产生非晶或玻璃相，称为GGBFS或水冷渣（WCS）。研究了6%氢氧化钠对潜水硬WCS的碱活化。纳米二氧化硅是一种超细材料，可以改变地质聚合物产品的力学、微观结构和热性能，并以干重的0%、0.50%、1%和1.5%的比例添加到地质聚合物混合物中。固化在100%相对湿度和38 ℃的温度下进行
Ground granulated blast furnace slag is a finely ground, rapidly chilled aluminosilicate melt material separated from molten iron in the blast furnace as a by-product. Rapid cooling results in an amorphous or a glassy phase known as GGBFS or water-cooled slag (WCS). Alkaline activation of latent hydraulic WCS by 6% sodium hydroxide was studied. Nano silica is an ultrafine material that can modify mechanical, microstructural and thermal properties of geopolymer products and added to the geopolymer mix in the ratio of 0, 0.50,1 and 1.5% of the dry weight. Curing was performed under 100% relative humidity and at a temperature of 38 o
