Construction Sand and Gravel - USGS Mineral Resources Programnatural resources and a major basic raw material, is used mostly by the construction industry. The construction sand and gravel industry is a major contributor to and an indicator of the economic well-being of the Nation, producing a high volume of basic products with low unit value.

Source: USGS, US .Stone, sand and gravel are recovered from wide- spread naturally occurring mineral deposits in the US for production as aggregates. Slag from iron and steel manufacturing was also a source for aggregates in earlier years. Aggregates are used in the construction of residential, commercial, and industrial buildings as well.
Processing of stone, gravel and sand - AltaMachines and equipments for stone, gravel and sand processing are mainly used in building industry. The range of machines type is biggest in this branch. It starts from the largest high-capacity stationary aggregates, including medium types in semi-mobile design and ends with the smallest ones mostly as mobile units.Labor Requirements: Sand and Gravel and Ready-Mixed . - Jstorby a unit quantity of ready-mixed concrete at the job site was required for manufacture and de- livery. The remaining three-fourths were re- quired for extracting, processing, and transporting the principal ingredients used - sand, gravel, and cement.
