This Japanese Industrial Standard 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 of, for example, demolition of a building.
The comparison table between previous and current editions of this Standard on technically significant revisions is given in Annex E.
NOTE Concrete lumps are generated not only by demolishing buildings but also by hardening the concrete which returned from concrete products and ready mixed concrete
