The results related to the engineering properties indicated that demolished concrete aggregates and crushed coarse tile aggregates can replace natural aggregates up to 30% and 60% respectively in the production of Grade 25 concrete.
Production of Crushed Rock Aggregate Today, if there is a vast deposit of aggregate material then quarries are used in order to extract this material. Modern blasting methods allow this to be possible in a quarry and aggregate is able to be separated out more efficiently.
Aggregate is mined from the earth, either dug out of pits or blasted out of quarries. This process has many significant environmental impacts. [1] Creating the pits or quarries requires the removal of virtually all natural vegetation, top soil and subsoil to reach the aggregate underneath. Not only does this lead to a loss of existing animal
