摘要 清水混凝土以其节约工程成本、提高工程质量、改善企业管理水平等优点,自20世纪90年代后期在技术研究及工程应用方面得到了长足发展。但清水混凝土黑斑问题依然严重影响着清水混凝土工程的施工质量。为了更好地促进清水混凝土科学研究与工程应用水平的提高,结合多个清水混凝土工程实践成果,以济南轨道交通清水混凝土工程为依托,开展了针对清水混凝土黑斑成因的研究,对清水混凝土黑斑应对措施进行了系统分析,形成了有针对性的研究成果。工程实践表明,应用清水混凝土黑斑应对措施研究成果可以显著避免清水混凝土黑斑的产生,有效提高清水混凝土的施工质量。 With its saving project cost,improving the quality of engineering and enterprise management level,etc, fair-faced concrete got rapid development in the technology research and engineering application since the late 1990 s. But black stain of fair-faced concrete still heavily affect the construction quality. In order to better promote the improvement of scientific research and engineering application of fair-faced concrete,combined with a plurality of engineering practice results,with the rail transport fairfaced concrete project as the background,it carried out the research on the factors of black stain of fairfaced concrete and the countermeasures of black stain were analyzed,which formed a targeted research results. Engineering practice shows that the countermeasures of black stain of fair-faced concrete can significantly avoid the black stain,effectively improve the construction quality of the fair-faced concrete.
