coarse and fine sand for concrete

Aggregates for Concrete GreenSpec

Coarse aggregates are particulates that are greater than 4.75mm. 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

Workability

Aggregates influence the workability of the concrete by the amount of aggregate, the relative proportions of fine and coarse aggregate, and the different aggregate properties. When flat or elongated particles are contained in the coarse aggregate, the quantities of sand, cementious material, and water must be increased.

What's the Difference Between Cement and Concrete?

Concrete Basics. In its simplest form, concrete is a mixture of paste and aggregates (sand & rock). The paste, composed of cement and water, coats the surface of the fine (sand) and coarse aggregates (rocks) and binds them together into a rocklike mass known as concrete. Within this process lies the key to a remarkable

Aggregate for home use Concrete Society

Aggregate for home use. In concrete the major constituent in terms of volume is the aggregate. In essence concrete is like an artificial rock, consisting of aggregate materials bound together by hydrated cement. Aggregates are classified as coarse or sand (fine) depending on whether they pass through a 5 mm sieve.
