• Corrosion resistance of self-compacting concrete

    2012-12-1 · Highlights The corrosion resistance of self-compacting concrete (SCC) has not been investigated yet. In the reported study the corrosion resistance of SCC incorporating quarry dust powder, silica fume and fly ash was studied. The chloride permeability of the developed SCC was low to moderate and the corrosion resistance was high.

Silica fume, also known as microsilica and nanosilica, is a highly reactive pozzolanic filler, which is used to achieve high strength and dense concrete. Silica fume is a by-product of the manufacture of silicon and ferrosilicon alloys from high-purity quartz and coal in a submerged

  • Study on Compressive Strength of Quarry Dust as Fine

    AbstractIntroductionLiterature ReviewTests on Quarry DustDiscussion on ResultsConclusionsThe concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust generated from quarries. By replacement of quarry dust, the requirement of land fill area can be reduced and can also solve the problem of natural sand scarcity. The availability of sand at low cost as a fine aggregate in concrete is not suitable and that is the reason to search for an alternative material. Quarry dust satisfies the reason behind the alternative material as a
