• Studies on Pumice Lightweight Aggregate Concrete

    The lightweight aggregate is an aggregate that weighs less than the usual rock aggregate and the quarry dust is a rock particle used in the concrete for the experimentation The significant intention of the proposed technique is to frame a mathematical modeling with the aid of the optimization techniques

  • Aggregate Base Course vs Crushed Concrete

    Crushed concrete aggregate base course is made from recycled concrete aggregate, which is created by grinding concrete that’s been reclaimed from demolished highways, buildings and other structures The concrete from these sites is then processed to remove metals, and screened to appropriate sizes

  • Grading of Aggregate and Fineness Modulus of

    The sieves used of concrete aggregate consist of a series in which the clear openings or sieves are 475 mm, 10 mm, 20 mm, 40 mm, 80 mm, for coarse aggregates, 236 mm, 118 mm, 600 microns, 150 microns, for fine aggregates When as

  • Effect of quarry rock dust on the flexural strength of

    From the results, it was observed that the flexural strength of concrete with 25% and 100% quarry dust were respectively 2% and 43% higher compared with concrete with no quarry dust By carrying out regression analysis, empirical formulas in the form y = ax b were obtained for concrete with quarry dust The equations were compared with formulas proposed by ACI, BS, IS codes of practice for estimating the flexural strength using the compressive strength of concrete
