The fine and coarse aggregates generally occupy 60% to 75% of the concrete volume (70% to 85% by mass) and strongly influ-ence the concrete's freshly mixed and hardened proper-ties, mixture proportions, and economy. Fine aggregates (Fig. 5-1) generally consist of natural sand or crushed stone with most particles smaller than 5 mm (0.2 in.).

Aggregate is a component of composite materials such as concrete and asphalt concrete. It serves as reinforcement (adding strength to the overall composite material), and for forming concrete mortar (by mixing with water, bitumen, Portland cement, lime and gypsum). It is also used as base material under foundations, roads, and railroads. Add to ...

Coarse Aggregate is normally greater than 5mm. Fine Aggregate is aggregate less than 5mm. Can be a single sized material typically 20mm, 14mm, 10mm,or 7mm or a graded aggregate consisting of a blend of single sized aggregate. Concrete Aggregates are produced to Australian Standards (AS 2758) or to more specific customer requirements.

Q. Are aggregates classified according to density? A. Yes. Those used to make normal-density concrete are called normal-density aggregates. Those for low-density concrete (historically known as "lightweight" concrete) that have an air-dried density at 28 days usually in the range of 1440 to 1850 kg/m 3 (90 to 115 lb/ft 3 ), are called low ...

10mm aggregate will need a depth of 30-40mm, but on a driveway, this would need to be at least 50mm. 20mm aggregate would need a depth of at least 40-50mm, and at least 50-60mm on driveways. Please note: The aggregate calculator's calculated tonnage is approximate. The exact conversion will depend on a few other factors, such as the bulk ...
