Recycling of Demolished Concrete

aggregate for road construction [Yanagibashi et. al 2002]. By recycling of demolished concrete, 30% of normal aggregates can be saved. It is also estimated that in the next ten years, the amount of demolished concrete will be increased to 7.5 ~ 12.5 billion tons [Torring and Lauritzen 2002 ]. If technology and general acceptance of using recycled aggregate are developed, there will be no ...
