percentage of crushed sand in concrete

Aggregates which account for 60 to 75 percent of the total volume of concrete are divided into two distinct categoriesfine and coarse Fine aggregates generally consist of natural sand or crushed stone with most particles passing through a 38inch sieve Coarse aggregates are any particles greater than 019 inch but generally range
