摘 要: 采用X射线光电子能谱元素定量分析 (XPS)、红外光谱分析 (IR)、X射线衍射分析 (XRD)和固体高分辨核磁共振分析 (2 9SiNMRMAS谱 )等多种微观测试手段 ,研究了碱激发碳酸盐矿胶凝材料的反应产物的种类和结构。结果表明 :改性水玻璃 (碱 )与碳酸盐矿粉的反应产物为凝胶物质 ,其主要组成是纤蛇纹石型的水合硅酸镁和白钙沸石型的水合硅酸钙 ,此外 ,还存在有一定数量的硅凝胶。 The typesand structureof the reaction products of alkali-activated carbonatites cementitious material were investigated by means of X-ray photoelectron spectroscopy for element quantitative analysis, infrared spectroscopy, X-ray diffraction and (()^(29)Si) nuclear magnetic resonance. Results show that the products of the reaction of carbonatites powder with modified water-glass are gel like substance, which are mostly comprised of magnesium silicate gel of chrysotile type, hydration calcium silicate of gyrolite type and a certain amount of silica gel as well.
