日本东京工业大学铃木敏郎教授,最近开发用碎冰粒代替水拌制混凝土的新方法,强度可提高2倍,并查明用5～35%的各种水灰比能制造出极高质量的混凝土。冰对混凝土来说,会引起冻害,虽然是敌对的,但与砂和水泥混合具有比水更易搅拌均匀的性质,因此,只要把造成降低质量原因的水量,最大限 Prof. Suzuki Suzuki of the Tokyo Institute of Technology, Japan, recently developed a new method of mixing concrete with crushed ice instead of water. The strength can be increased by a factor of 2, and the use of 5 to 35% of various water-cement ratios can produce extremely high quality. Concrete. Ice can cause freezing damage to concrete. Although it is hostile, mixing with sand and cement has the property of being easier to stir and mix than water. Therefore, as long as the amount of water that causes the deterioration of quality is limited,
