Aggregates are raw materials that are produced from natural sources and extracted from pits and quarries, including gravel, crushed stone, and sand. When used with a binding medium, like water, cement, and asphalt, they are used to form compound materials, such as asphalt concrete and Portland cement concrete.
In crushed sand, the presence of these contaminants is rare (at least in Scandinavia) and some level of fines would normally increase the content of filler-modified cement paste, thus helping with lubrication between the coarser aggregates particles (≥ 0.125 mm or 120 mesh). When the optimum level of fines content is exceeded, they start ...
