道路再生混凝土基本性能的探讨

道路水泥混凝土的再生是将废弃混凝土制造成混凝土集料后又重新用于混凝土的一种物质资源的循环方法,目前该方法越来越多地被使用到工程实践当中。从理论上分析了再生混凝土的特性及影响新拌再生混凝土特性的因素。通过与普通混凝土相比,可知再生混凝土具有粘聚性和保水性较好、流动性较差、抗压强度稍低、耐磨性基本相同等特点。结果表明:道路混凝土的再生具有良好的经济性和较大的发展潜力。

Discussion on Characteristics of Recycled Aggregate Concrete Pavement

The regeneration of the concrete is a material-source cycle method which produces new concrete aggregate from waste concrete, and the method is increasingly being used in practice. This paper theoretical and the factors which affect the properties analizes the characteristics of renewable concrete. Compared with ordinary concrete, recycled concrete has the characteristics like the better water retention, the poor liquidity, lower compressive strength, and the same wear resistance. So recycled concrete aggregate is a good economic regeneration and great way for further development.
