  • Partial Replacement Of Coarse Aggregate With Broken

    In this study we replaced natural aggregates with recycled aggregates in concrete cubes This is the first part of the study we have to do Here we are trying to see a pattern of how the strength decrease once we replace natural coarse aggregate (NCA) with recycled coarse aggregates (RCA) The percentages of replacement will be 0 50 and 100.Of fine aggregate with stone dust The results shows strength of concrete increases within 5 12 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 than referral concrete (concrete with zero percent stone dust).
