The research was conducted by testing concrete cylinder and cubes specimens at ages of 7,14 and 28days concrete with concrete mix ratios 1:1.5:3 with a target strength of 25N/mm and 1:2:4 with a target strength of 20N/mm. Samples of concrete specimens were made using varying contents of quarry dust and laterite as fine aggregate.
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 …
