莫斯科建筑工程学院对破碎混凝土所获得的二次骨料进行了研究。这是因为目前某些资料相互矛盾,介绍这种骨料混凝土性能的论著很少,而且二次资源和节能工艺的有效利用,以及生产废料日益增多所带来的环境保护问题越来越突出。 用边长10cm的立方体和10×10×40cm The Moscow School of Civil Engineering and Architecture studied the secondary aggregate obtained from broken concrete. This is because some of the current data are in conflict with each other. There are few articles on the performance of such aggregate concrete, and the effective use of secondary resources and energy-saving technologies, as well as the increasing environmental protection problems caused by the increasing production of waste materials, have become increasingly prominent.
