再生混凝土国内外研究现状综述

A summary of the research status of recycled concrete at home and abroad

再生混凝土是将废弃混凝土回收、破碎、分级后作为粗骨料再利用,并掺加水、水泥和外加剂混合搅拌后形成的新混凝土,其可以实现建筑垃圾的有效再利用,有益于保护环境,节约自然资源。在我国城镇化的稳步推进过程中,再生混凝土具有广阔的发展前景,再生混凝土的应用将产生巨大的经济效益和环境效益。

Recycled concrete is a new concrete. It is formed through the process that the waste concrete is recycled, crushed and graded as coarseaggregate to reuse, with water, cement and admixture being mixed. Recycled concrete can effectively realize the reuse of construction waste, whichis beneficial to the protection of the environment and the conservation of natural resources. In the steady progress of urbanization in China, recycledconcrete has broad prospects for development. And the application of recycled concrete will bring huge economic and environmental benefits.
