Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world.
Crushed stone is one of the most accessible natural resources, and is a major basic raw material used by construction, agriculture, and other industries. Despite the low value of its basic products, the crushed stone industry is a major contributor to and an indicator of the economic well-being of a nation.

Production totaled 1.33 billion metric tons, which were valued at more than $15 billion. In 2016, crushed stone production reached 1.36 billion metric tons. While overall production of crushed stone dipped in 2017, the average value per metric ton has increased by $1.51 or 15.2 percent since 2013.
PRODUCTION OF CRUSHED--STONE AGGREGATE In operating a quarry and crushing plant, the drilling pattern, the amount of explosives, the size shovel or loader used to load the stone, and the size of the primary crusher should be coordinated to assure that all stone
for aggregate production come from bedrock or unconsolidated deposits. The vast majority of materials used in the mineral aggregate industry are obtained from surface-mined stone quarries or from sand and gravel pits. How materials are extracted influences their quality.

Construction aggregate, or simply "aggregate", is a broad category of coarse particulate material used in construction, including sand, gravel, crushed stone, slag, and recycled concrete. Aggregates are a component of composite materials such as concrete and asphalt concrete; the aggregate serves as reinforcement to add strength to the overall composite material.
Aggregates demand is expect to reach 7.7 million tons per capita, up for 6.6 million tons per capita in 2012. Growth by Product Type Globally, crushed stone production is predicted to grow by an average of 7.7 percent annually, according to the study. By contrast, sand production is only expected to grow by an average of 3.9 percent annually.
