| 摘 要： | 通过XRD和SEM等测试手段，对微波辐照煤矸石硅酸盐水泥砂浆的微结构进行了分析。结果表明，微波辐照煤矸石能充分激发煤矸石的活性，使煤矸石与硅酸盐水泥水化后所产生的Ca(OH)2充分反应生成CaCO3等物质，从而提高普通混凝土制品的耐久性和强度。

| Abstract: | The microstructure of portland sanded cement mortar of microwave radiated coal gangue is analysed by XRD and SEM. The results have shown that microwave radiation can fully exciting the activity of coal gangue, making it to react fully with Ca(OH) 2 which produced after hydration of silicate cement to form CaCO 3. Therefore, the strength and durability of portland cement concrete products can be improved. |
