Aggregates for Concrete

concrete. A typical consensus specification for fine and coarse aggregate for concrete is ASTM C 33. Synthetic aggregates may be either byproducts of an industrial process, in the case of blast-furnace slag, or products of processes developed to manufacture aggregates with special properties, as in the case of expanded clay, shale, or slate used for lightweight aggregates. Some lightweight ...

- 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 .

Aggregate is usually described as either coarse aggregate (retained 4.75 mm) or fine aggregate (passing 4.75 mm). Aggregates generally make up about 95 percent of the total mass of hot-mix asphalt mixtures and 80 percent by mass of concrete - aggregate properties are, therefore, critical for quality hot-mix asphalt or concrete. Typically, hot-mix asphalt mixtures consist of 50 percent coarse ...
