轻骨料混凝土区别于普通混凝土的一个特点,是其在工程中的应用不但要满足结构对强度的要求,而且要满足结构或保温对容重的要求。如何在配比设计中满足这两方面的要求是很有实际意义的问题。 One of the characteristics that distinguishes lightweight aggregate concrete from ordinary concrete is that its application in engineering not only satisfies the structural requirements for strength, but also meets the requirements of structure or insulation for bulk density. How to meet these two requirements in proportioning design is a very practical issue.
