Soil texture is defined as the distribution of mineral particles less than 2 mm in diameter (fine earth fraction): clay (<0.002 mm), silt (0.002–0.63 mm) and sand (0.063–2 mm). Particles larger than sand are considered coarse fragments, and include gravel (2–64 mm), cobbles (64 mm-256), and boulders (>256 mm).

Sieve sizes commonly used for concrete aggregates are detailed in Table 1, and various physical properties of normalweight aggregates, with typical range values, are shown in Table 2. Coarse and fine aggregates are generally sieved separately. That portion of an aggregate passing the 4.75 mm (No. 4)
produced in South Africa annually on approximately 3,1 million ha of land. Half of the production consists of white maize, for human food consumption. Maize needs 450 to 600 mm of water per season, which is mainly acquired from the soil moisture reserves. About 15,0 kg of grain are produced for each millimetre of water consumed. At maturity,
Building Aggregates. Grano (6mm - dust) for use in mixing with cement to make fine concrete. Place on top of a new concrete surface and polish for a tough finish. Grano Dust is gritty aggregate typically manufactured from either limestone or granite. Widely used in construction and building it is a flexible material.
predominantly larger than 5 mm (0.2 in.) and generally between 9.5 mm and 37.5 mm (3⁄ 8 in. and 11⁄ 2 in.). Some natural aggregate deposits, called pit-run gravel, consist of gravel and sand that can be readily used in concrete after minimal processing. Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed.

AGGREGATES Aggregates (or mineral aggregates) are hard, inert materials such as sand, gravel, crushed stone, slag, or rock dust. Properly selected and graded aggregates are mixed with the cement-ing medium asphalt to form pavements. Aggregates are the principal load-supporting components of an Asphalt Concrete pavement.

- 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. • Larger aggregate diameters reduce the quantity of cement and water needed. 20 mm aggregate . Common aggregates
