Crushed rock sand has surfaced as a viable alternative to Natural River sand and is being now used commonly throughout the world as fine aggregate in concrete It is manufactured by crushing the quarried stone to a size that will completely pass through 475 mm sieve
The Effect of Aggregate Properties on Concrete Concrete is a mixture of cementious material, aggregate, and water Aggregate is commonly considered inert filler, which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete
Jun 02, 2016· This suggests that clay-free fines contents ranging from 1% to 9% for a particular mix design do not have a significant effect on the slump of the concrete For a constant slump value an increase in fine aggregate fines content would generally demand higher admixture volum
with 20% replacement of sand with manufactured sand 40% replacement is possible and 50% replacement gave higher strength Quarry dust fine aggregate decreased the compressive strength due to deficient grading and excessive flakiness The w/c ratio and slump value increased with the replacement of sand, Voids present in quarry
