Aggregates are inert granular materials such as sand, gravel or crushed rock that are an endproduct in their own right. They are also the raw materials that are an essential ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete

Difference Between Fine and Coarse Aggregate Civil

River sand or machine sand, crushed stone sand, crushed gravel sand are the major sources of fine aggregate. Dolomite aggregates, crushed gravel or stone, natural disintegration of rock are the major sources of coarse aggregate. 5: Surface Area: The surface area of fine aggregates is higher. The surface area of coarse aggregate is less than fine aggregates. 6: Function in Concrete: The voids

concrete fine aggregate alternate for river sand

Aggregate is a granular material, such as sand, gravel, crushed stone used with a cement to produce either concrete or mortar. Aggregate is relatively inexpensive and does not enter into complex chemical reactions with water; it has been customary, therefore, to treat it as inert filler in concrete and mortar.get price. Use of Manufactured Sand in Concrete and Construction An. The cement

Aggregates Portland Cement Association

Aggregates, which account for 60 to 75 percent of the total volume of concrete, are divided into two distinct categories--fine and coarse. Fine aggregates generally consist of natural sand or crushed stone with most particles passing through a 3/8-inch sieve. Coarse aggregates are any particles greater than 0.19 inch, but generally range between 3/8 and 1.5 inches in diameter. Gravels
