In lTI2ny countries, a considemble amount of demolition waste IS generated and concrete forms a signiftcallt proportion of the waste. The neceSSity for the lIse of recycled aggregate in concrete arises due to the following reasons : (1) diminishing supplies of natuml aggregates; (2) securing ample supply of concrete aggregates to the construction industry; (3) dirninisrl! ng dumping area within the utban limits; and (4) avoid,ing danger to marine life by limiting the indiscriminate dumping of highly alkaline nature of concrete in the sea. It is the purpose of thiS report to improve the quality of recycled aggregate concrete and to put to practical use of such concrete.
