Concrete sand is a type of sand that is primarily used in the production of concrete and other construction materials.
Concrete sand typically has larger and more consistent particle sizes compared to natural sands.
Concrete sand contributes to the workability of the concrete mixture, making it easier to mix, place, and finish.
The usual range employed is between 9.5mm and 37.5mm in diameter. - Fine aggregates are usually sand or crushed stone that are less than 9.55mm in diameter. Typically the most common size of aggregate used in construction is 20mm. A larger size, 40mm, is more common in mass concrete.
