Aggregate Properties You Need to Know: Strength

Production and ResourcesTesting For ToughnessSelecting Methods and EquipmentConstruction aggregates are extracted from natural sand and gravel deposits or quarried from rock formations. The raw, mined materials are crushed to suitable sizes if required, then sorted by size and shape for use as fine or coarse fractions. These mining operations produce some 2.5 billion tons of construction aggregates annually for the U.S. domestic market. Manufactured aggregates are a separate source of materials derived 在globalgilson上查看更多信息
