Development of reuse technology of roasted ash for the construction materials

Abstract

We developed the new technology for ash treatment, ash roasting. This method is more economical and easier of maintenance than ash melting. This paper describes the outline of reuse technic of roasted ash for the construction materials, for example, aggregate. We find that roasted ash have a good points in support strength and handling. Using this material, we can make a strong paved street. The recycle material from roasted ash, we call Koka 21, is already applied for a lot of road constructions in Mie prefecture.
