Aggregates for Concrete

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. Crushed stone is produced by crushing quarry rock, boul-ders, cobbles, or large-size gravel. Crushed air-cooled

Aggregates for Concrete

aggregate and crushed stone coarse and fine aggregate are produced by crushing natural stone. Crushing, screening, and washing may be used to process aggregates from either sand and gravel deposits or stone quarries. Aggregates may be produced from igneous, sedimentary, or metamorphic rocks, but geological type does not by itself make an aggregate

Crushed Stone - an overview ScienceDirect Topics

Boreholes were drilled to examine the depth of the crushed stones after soil improvement. One of the borehole logs is shown in Fig. 18.8.The stones were found to be present up to 9 m, in which the top 5 or 6 m was densely packed, whereas the remaining 4 or 5 m was embedded in clay.Below the crushed stone layer were a silty gravel layer and the weathered sandstone layer.
