在水泥耗量侭可能低的情况下改善水工混凝土的質量和提高它的耐久性是近代混凝土制作技術过程中最重要的問題。有些建設工程混凝土的質量同調制混凝土所用的材料,尤其是水泥的質量和数量比起來还是不很高的虼?
It is the most important issue in modern concrete production technology to improve the quality of hydraulic concrete and to improve its durability when cement consumption is likely to be low. Some construction projects with the quality of concrete used in concrete materials used, in particular, the quality and quantity of cement is still not very high 虼?
