Study on Compressive Strength of Quarry Dust as Fine

The 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 andA concrete mix ratio of 2:3:6 (cement: laterite/sand: granite) with water/cement ratio of 065 was adopted for this investigation The laterite content in the fine aggregate was varied from 0 toCompressive strength of concrete using lateritic sand and
