of fine aggregate with stone dust. The results shows strength of concrete increases within 512 percent up to 50 percent replacement of fine aggregate. And at 60 percent stone dust in concrete the maximum value of compressive strength is obtained which is 17 percent more than referral concrete (concrete with zero percent stone dust).
