Crushed Stone Statistics and Information USGS

Crushed stone, one of the most accessible natural resources, is a major basic raw material used by construction, agriculture, and other industries that utilize complex chemical and metallurgical processes. 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 the Nation.

Crushed Stone an overview ScienceDirect Topics

9.3 Substitutes and manufactured aggregates. Crushed stone can generally substitute for sand and gravel, and vice versa. There are only a few naturally occurring materials that have the properties necessary to make an in-kind replacement for aggregate. Shells, caliche (carbonate-cemented soil typical of arid areas), and clinker (rock hardened by heat from natural coal fires) can substitute for

Global Crushed Stone Aggregate Market And Trends

Global crushed stone demand is growing. It is estimated that the global aggregate production is about 50 billion tons. According to the world’s total population of 7.7 billion, the per capita consumption of sand and gravel is about 6.5 tons. In terms of regions, Asia accounts for 66% of the global sandstone production.

What is Crushed Aggregate? (with pictures)

Crushed aggregate, also known as rock aggregate, refers to a crushed stone product produced in quarries. In areas where natural sand and gravel aggregate deposits are insufficient to handle local demand, larger stones are processed in an impact crusher to create crushed rock aggregate. The greater costs of production involved in mining and processing the stones to create crushed aggregate
