【摘要】 研究白云岩石粉材料性能特性及在混凝土中技术路线下,对混凝土耐久性的影响,进行微观电镜和孔结构分析,探讨白云岩石粉在混凝土中的作用机理,得出了白云岩石粉主要成分为CaO、MgO和SiO2,MgO含量较高;除中低强度等级、大体积混凝土外,白云岩石粉的适宜掺量为小于30%等结论。更多还原

【Abstract】 This paper studied the property of dolomite powder and its influence on concrete durability,carried out transmission electron microscope analysis and pore structure analysis, and discussed the action mechanism of dolomite powder in concrete. It was found that the main ingredients of dolomite are CaO,MgO and SiO₂, among which Mg O content is the highest; except low-strength, medium-strength and massive concrete, the appropriate mixing amount of dolomite powder is less than 30%.更多还原
