碳硫硅钙石对混凝土的破坏作用
SEM-EDS analysis shows that gypsum and AFt are the main products formed after the corrosion of cementitious materials,but magnesium sulfate and thaumasite were not found.
采用偏光显微镜和扫描电镜分析了含镁质类膨胀剂的水泥砂浆在硫酸盐溶液中浸泡1 a后的微观结构,提出了硫酸盐溶液在水泥基材料中的3种迁移方式;通过SEM-EDS分析得出了该水泥基材料被侵蚀后所形成的产物主要是石膏和钙矾石的结果,没有发现硫酸镁和碳硫硅钙石膨胀物形成;在水泥基材料中添加适当种类和掺量的镁质类膨胀剂,水化的与未水化的膨胀剂填充到集料与浆体的间隙内,增大了水泥基材料的密实度,改善了界面结构,提高了水泥基材料抗硫酸盐侵蚀能力。
