Abstract

In Japan, it has been predicted that enormous quantities of demolished concrete will be produced in the future. Therefore, a great deal of research is being conducted to find ways to recycle this demolished concrete as concrete aggregate. However, because the characteristics of the original concrete are not well known in many cases, the results are also not clear. Moreover, the recycling of the cement in concrete is also necessary from the standpoint of resolving global environmental problems and achieving sustainable development. This paper describes the properties of the concrete made with recycled aggregates from the original concrete of known quality and the recycling of the cement in concrete as the approach that should be taken in the 21st Century.

拆卸混凝土的循环再造
在日本,据预测,未来将产生大量的拆除混凝土。因此,人们正在进行大量的研究,寻找回收这些拆除的混凝土作为混凝土骨料的方法。然而,由于在很多情况下对原混凝土的特性不太了解,结果也不清楚。此外,从解决全球环境问题和实现可持续发展的角度来看,混凝土中水泥的回收利用也是必要的。本文介绍了用已知质量的原混凝土再生骨料制成混凝土的性能,以及21世纪混凝土中水泥的再生利用应采取的方法。
