- Synopsis
- Three kinds of recycled aggregate and the recycled concrete were established as Japanese Industrial Standards from 2006 through 2007. However, the supply in the market of the normal ready-mixed concrete can afford to be enough under the present conditions, and therefore recycled concrete does not come to spread. Therefore this study compared the influence that the use of the recycled concrete gave to economy, quantity of CO2 outbreak, energy consumption by a case study based on a model of the reconstruction project of the apartment complex. In addition, this study used the recycled aggregate of the M class for recycled concrete. The reason depends on there being little disposal amount of resources to occur secondarily in production of the recycled aggregate.
