This experimental study presents the variation in the strength of concrete when replacing sand by quarry dust from 0% to 100% in steps of 10%. M20 and M25 grades of concrete are taken for the study keeping a constant slump of 60mm. The compressive strength of concrete cubes at age of 7 and 28 days is obtained at room temperature. Split tensile strength and flexural strength of …

104· One notable difference with sand and gravel workings, however, is that these generally require a higher rate of land use. Sand and gravel deposits tend to be shallow in nature and therefore, for an equivalent volume of production, greater areas of land require disturbance. Set against that, is the opportunity for progressive restoration that arises in shallow sand and …

Difference between sand and gravelGravel Characteristics Composition: Gravel is composed of larger particles, typically ranging from 2 mm to 64 mm in diameter. It often consists of rock fragments and is commonly used as a stable base or drainage layer in construction projects. Size: Due to its larger size, gravel provides better stability and support for structures compared to sand.
