Recycling of Brick Aggregate Concrete as Coarse

Also in-situ strength of an old structure has been compared with the compressive strength of recycled aggregate concrete made with the recycled aggregate collected from the same structure Based on this investigation it is revealed that recycled brick aggregate can be used as coarse aggregate for making concrete of strength 20 7 to 31 0 MPa...
