日本《朝日新闻》今年二月报道,东京工大建筑系铃木敏郎教授实验发现,用冰渣代替水搅拌混凝土,能提高水泥质量。混凝土是由水泥、砂、砂砾和水搅拌成的。水与水泥起化学反应而凝固。一般用水量应该是相当于水泥的百分之二十至二十五。但搅拌水泥同合面一样,水量太少,不易揉合均匀,因此在实际操作中往往加水达百分之四十至六十,其中一半水是多余的,从而导致水泥 The Asahi Shimbun of Japan reported in February this year that Professor Suzuki Hiroshi of Tokyo University of Technology’s Department of Architecture had found out that the use of ice dregs instead of water to agitate concrete can improve the quality of cement. Concrete is agitated by cement, sand, gravel, and water. Water reacts with cement and solidifies. The general water consumption should be equivalent to 20 to 25 percent of the cement. However, the agitated cement is the same as the joint surface, the amount of water is too small, and it is not easy to knead evenly. Therefore, water is often added by as much as 40 to 60 percent in actual operations. Half of the water is superfluous, resulting in cement.
