As concrete production keeps on increasing worldwide, so does the use and consumption of abiotic resources, such as aggregates.To corroborate this statement, the worldwide aggregates demand will raise from 45.
Aggregate production line production process is as follows: 1) large stone by the silo by the vibrating feeder evenly sent to the jaw crusher for coarse crushing, coarse crushed stone by the conveyor belt to the impact crusher for further crushing.
A synthetic aggregate may also be the byproduct of manufacturing and a final burning process—blast furnace slag is an example of a synthetic aggregate.Briefly, blast furnace slag is formed when iron ore or iron pellets, coke, and a flux (such as limestone, caco 3, or dolomite, caco 3 ·mgco 3) are melted together in a blast furnace.
Coarse aggregate consists of either (or a combination of) gravel, crushed gravel, crushed stone, air-cooled blast furnace slag, or crushed concrete, with particles generally larger than 0.The maximum size of the coarse aggregates is generally in the range of 3/8 to 1 ½ inches.Read more on why we use aggregates in concrete.

The cement manufacturing process flow chart is shown as follows: cement manufacturing process 1crushing and preblending (1)crushing: in the cement manufacturing process, most material must be broken, such as limestone, iron ore, clay and coal etc limestone is the main raw material for cement production, each producing a ton of clinker needs.
The concrete industry is a core element of the building sector, but it has to deal with the increasing attention on the environmental issues related to the production process: increasing energy efficiency and the adoption of alternative fuels or raw materials represent the most relevant solutions.The present work analyses physical, mechanical, and environmental performances of concrete .
The extracted raw material was taken to an impact mill plant for grinding so that coarse recycled aggregate could be obtained.In the same plant, the virgin material coming from a bank was crushed to obtain the fine and coarse aggregates, and then, the tests were carried out.In tables 1 and 2, aggregate properties and mixture design are indicated.
The objective of any concrete aggregate processing operation should be the production of good-quality, ‘clean’ coarse and fine materials in the normal range of sizes.
The main findings of this investigation revealed that the waste material could be reused successfully as partial substitutes for coarse aggregates in concrete production and the optimum strength of the concrete was observed at 25% of waste glass against 75% of granite for coarse aggregate, whereby the compressive strength of the concrete cube .
The selection of good quality coarse aggregate is essential for the production of concrete that meets the desired strength and durability requirements.Ideal construction aggregate should have a rough surface texture and should be clean, strong, and free from coating and other dirt particles.
