Quarry Dust Portland Cement Dry Mix Ratio
Quarry Dust Fine Powder as Substitute for Ordinary Portland Cement in Concrete Mix 193 Journal of Engineering Science and Technology April 2014, Vol 9(2) enhances compressive strength at hardened state [3]Ordinary Portland Cement of grade 53 with 30 percent laboratory in the dry form and then water was added to (60% of quarry dust and 40% natural sand) mix ratio was the optimum mix TheOptimum Mix of Quarry Dust as Partial Replacement of
The quarry dust is rich in SiO 2 (454%), while the Portland limestone cement is rich in CaO (6114 %) and deficient in SiO 2 (2140%) Quarry dust's high shear strength makes it an excellent geotechnical material (Soosan et al, 2005; EzeUzomaka and Agbo, 2010 , Amadi, 2011 )A Mix proportioning Two grades of concrete M20 and M25 having nominal mix proportion of 1:15:3 and 1:1:2 respectively were used by weight and w/c ratio was fixed according to the slump requirement of 60mm For this concrete mix, quarry dust was added for replacement of sand from 0% to 100% in step of 10%Use of Quarry Dust to Replace Sand in Concrete – An
