The study explains that quarry dust has required properties of fine aggregate and 50% of quarry dust can be replaced in sand to produce optimum strength of concrete. 25% replacement of quarrydust with fine aggregate gives same strength values as control mix
Read MoreThe use of natural sand as fine aggregate in concrete is becoming problematic due to scarcity and pressure on mining of the resource. Alternate sources such as the use of industrial waste as replacement of natural sand in concrete are gaining popularity as a sustainable construction material.
Read MoreRed soil is a type of soil that develops in a warm, temperate, moist climate under deciduous or mixed forest, having thin organic and organic-mineral layers black brown leached layer resting on an illuvium red layer.Red soils are generally derived from crystalline rock. They are usually poor growing soils, low in nutrients and humus and difficult to be cultivated because of its low water
