这种制造轻混凝土的方法的特点是使用经防水处理的轻集料,这样,由轻集料的吸水性所造成的水泥浆或水泥石的脱水作用进行得很缓慢,因此,在制造轻混凝土时,可以象制造重混凝土时一样使用较低的水灰比(c/w)。除此以外,由于在这种方法中,轻集料在轻混凝土的制造过程中仍保持干燥状态,因此仍能保留粒状轻集料的强度。 This method of manufacturing light concrete features the use of water-repellent light aggregates, so that the dewatering effect of the cement paste or cement stone caused by the water absorption of the light aggregates proceeds very slowly, and therefore, the manufacture of light concrete At the same time, a lower water-cement ratio (c/w) can be used as in the case of heavy concrete. In addition to this, due to this method, light aggregates remain dry during the manufacture of the light concrete, so the strength of the granular lightweight aggregate can still be retained.
