There are many different types of aggregate, some are natural aggregate, there are also large volume of crushed bedrock or gravel, boulders, sand, and sediment used as aggregate materials. In city infrastructure construction, most aggregate is used to make concrete.
Aggregate is also used in the production of asphalt, and great quantities are needed to build roads, pipelines, airstrips, and building pads. Aggregate is also used in water filtration systems, and we spread it on roads in winter to provide traction.
Aggregates constitute 90 to 95 % volume of concrete and shape of aggregates influence many a properties of fresh and hardened concrete.
Quarrying is a series activity of removing layers or large pieces of stone from an identified and unearthed geologic deposit. Differences in the particular quarrying techniques used often stems from variations in the physical properties of the deposit itself-such as density, fracturing/bedding planes, and depth-financial considerations, and the site owner’s preference.
Nevertheless, the process is relatively simple: locate or create breaks in the stone, remove the stone using heavy machinery, secure the stone on a vehicle for transport, and move the material to storage.
