一“冷”混凝土是在低温和严寒条件下,用不加热的材料,掺入大量氯盐拌制而成的。它在浇灌后也不再加热,在一定的时间内冷却硬化,并在受冻前达到规定强度。“冷”混凝土是苏联冬季施工中的一项先进经验。北京市道路工程于1956年初开始作“冷”混凝土试验。当时,在香山至八大处等路段采用了“冷”混凝土施工方法。
A “cold” concrete is made from a mixture of a large quantity of chloride salt, using unheated materials under cold and cold conditions. It is no longer heated after watering, cooling hardened within a certain period of time, and to reach the required strength before being frozen. “Cold” concrete is an advanced experience in the winter construction of the Soviet Union. Beijing road engineering began in early 1956 as a “cold” concrete test. At that time, Xiangshan to Badachu and other sections of the “cold” concrete construction methods.
