再混凝土作为当今建筑垃圾循环利用的主要形式以及世界众多国家环境保护和可持续发展的目标之一,已经在各国广泛推广。由于再生混凝土骨料自身存在的一些缺陷,比如孔隙率高、吸水性大等特征,导致各项性能不高,从而限制了它的应用范围及推广力度,因此有必要进行改性研究,使之高性能化。文章基于此主要探讨了再生混凝土配合比方案。
Re-concrete has been widely promoted in various countries as one of the main forms of recycling of construction waste today and one of the goals of environmental protection and sustainable development in many countries around the world. Because of the inherent defects of recycled concrete aggregates, such as high porosity, large water absorption, etc., resulting in low performance, which limits its application range and promotion efforts, it is necessary to carry out modification studies to make High performance. Based on this, the article mainly discusses the mix proportion scheme of recycled concrete.
