Compressive Strength of Concrete Made with Quarry Rock Dust and Washed 10mm Washed Gravel as Aggregates
This work is related to study the compressive strength of concrete using quarry dust as fine aggregate instead of sand and 10mm washed aggregate instead of conventional granite. Three mixes of 1:2½:3, 1:1½:2 and 1:1:2 (by weight) and at water-cement ratios (w/c) of 0.65, 0.60 and 0.45 for grade 20, 30 and 40 respectively were designed. However, these mixes gave characteristic strengths of 18.88N/mm2 28.23N/mm2 and 38.29N/mm2 respectively equivalent to grade 15, 25, and 35 respectively. Though the aggregate/cement ratio of concrete is lower than that of conventional granite concrete, workability value compared favourably with the conventional granite concrete.Therefore the 10mm washed aggregate and quarry dust satisfied the requirements of code provision in properties studies and can serve as full replacement for conventional granite and natural river sand respectively.
