- Synopsis
- Most of concrete mass has been used as base course materials. In recent years, production of concrete mass increase rapidly, and it is required that other way to recyle concrete mass on reduce environmental load. Recycling recycled aggregate to concrete has already been put to practical use partially, and the recycled aggregate and the recycled aggregate concrete is standardized in Japan Industrial Standard (JIS). This paper introduces outline of recycled aggregate produced by rotary crushing system, and properties of concrete using recycled aggregate. And it describes application way of recycled powder that is a by-product when produced recycled aggregate from concrete mass.
