Construction aggregate Wikipedia

OverviewHistoryModern productionRecycled materials for aggregatesSee also

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. 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. Due to the relatively high hydraulic conget price

OverviewGeneral informationSpecificationsDispenser configurationsSee also

Gravel mines, also called Button mines, were small United States made air-dropped anti-personnel mines. They were used extensively during the Vietnam War as part of the McNamara Line. They were also used as a rapid-deployment area denial expedient, to provide a barrier during combat search and rescue (CSAR) operations between downed pilots or other endangered units and infantry threats. get price

3. The Environmental Impacts of Aggregate Extraction

Aggregate is mined from the earth, either dug out of pits or blasted out of quarries. This process has many significant environmental impacts. Creating the pits or quarries requires the removal of virtually all natural vegetation, top soil and subsoil to reach the aggregate underneath.get price

Aggregates are the building blocks of modern civilization.

The production of recycled aggregates, mostly from concrete and asphalt pavements, has been increasing in recent years. Replaced and reconstructed old roads and buildings have become major sources of "recyclable materials." In some applications, recycled aggregate can compete with newly mined aggregates on price and quality.get price

Sand and Gravel Mining Industry Additional Information

Sand and Gravel Mining Industry. When rocks erode out of the Rocky Mountains and are carried downstream by streams and rivers, they break apart making sand and gravel. The sand and gravel settles out of the water and form the river bed. As the river channel moves across the landscape, the sand and gravel (aggregate) deposits are left behind.get price

Sand Extraction: 1. Introduction

The mining of aggregates in rivers can have an effect on pollution and change the level of water acidity (pH). Removing sediment from rivers causes the river to cut its channel through the bed of the valley floor (or channel incision) both upstream and downstream of the extraction site.get price
