This Japanese Industrial Sandard specifies the recycled aggregate for concrete-class H (hereafter referred to as "recycled aggregate H") manufactured by giving high level treatment such as crushing, grinding and classification to the concrete lumps generated as a result, for example, of pulling down a building. NOTE : Concrete lumps are generated not only by pulling down buildings but also by hardening the concrete which returned from concrete products and ready mixed concrete.
