Application of concrete and concrete products using aggregate made from industrial waste

近年来，由于环境保护的影响日益加大，可利用储量不断减少，以及利用工业废物、建筑副产品、生活废物进行回收利用的需求不断增加，全球混凝土用天然骨料出现短缺。针对这种情况，高质量再生骨料和混凝土制品技术取得了迅速进展。阐明现有建筑物低强度混凝土的力学特性和耐久性具有重要意义。

Recently natural aggregate for concrete is running short globally, due to the increasing influence of environment protection, and because accessible reserves are dwindling and demand for recycling method is increasing using industrial wastes, construction by-products, life wastes. Toward this situation, the progress on high quality recycled aggregate and concrete-products techniques has been made rapidly. It is important to clarify the mechanical characteristics and durabilityes of low strength concrete from the existing buildings.
