  • Concrete aggregates properties crushed by jaw and impact

    01/01/2019· Demolished building concrete samples were collected and primarily crushed at an impact crusher on site. A pre-crushed concrete sample was obtained with approximately 2″ (50 mm) top-size. Steel bars were removed manually after primary crushing. An impact crusher was used in the concretes with lower strength to check if improvements in cement paste liberation were observed.
