Quarry dust has been used for different activities in the construction industry, such as building materials, road development materials, aggregates, bricks, and til The present research work mainly deals with the influence of different replacement proportion of sand with quarry .
In addition to construction projects, aggregates can also be used in drainage, water filtration and erosion control. They can also be used as a fill material in site preparation and embankment projects. We at CEMEX continuously seek new ways to use aggregates to improve drainage, heat absorption, and other forces that impact the environment.
Aggregates are the most mined material in the world. Construction aggregate is a broad category of granular raw material of different sizes (sand, gravel, crushed stone, slag, recycled concrete etc) used in construction. Aggregate can be used in a number of ways in construction. In roads and railway ballast the aggregates are used to resist the overall (static as well as
A stone quarry typically produces the following products: Large size blocks blasted from the quarry face, from approximately 0.5 m 3 (approximately 0.36 tonne weight) to 1.25 m 3 (approximately 5-6 tonne weight), are called rip rap or rock armour and are used in coastal and river flood defence schemes to shore up sea fronts and river banks.
Another environmental issue with cement and concrete production is water pollution. The concern is the greatest at the concrete production phase. "Wash-out water with high pH is the number one environmental issue for the ready mix concrete industry," according to Richard Morris of the National Ready Mix Concrete Association.
