【摘要】 道路基层用缓凝硅酸盐水泥属于专用水泥,具有缓凝微膨胀特点,应用于道路基层可有效解决基层开裂问题。比较区别了道路基层用缓凝硅酸盐水泥和通用硅酸盐水泥,综述了道路基层用缓凝硅酸盐水泥研究现状,并调研了国内道路基层用缓凝硅酸盐水泥生产现状和实物质量,最后指出了道路基层用缓凝硅酸盐水泥研究和生产中存在的问题。更多还原

【Abstract】 The slow-setting Portland cement for roadbases(PRS) belongs to special cement, different from the common Portland cement, with property of slow setting and slight-expansion, which could effectively solve the crack problem when used in roadbases construction. The PRS cement and common Portland cement were compared, the PRS cement research status was summarized, and the domestic PRS cement production status and quality was investigated. Finally, the research and production problems of PRS cement were pointed out.更多还原
