Concrete is more workable when smooth and rounded aggregate is used instead of rough angular or elongated aggregate. Most natural sands and gravel from riverbeds or seashores are smooth and rounded and are excellent aggregates. Crushed stone produces much more angular and elongated aggregates
The aggregate gives volume, stability, resistance to wear or erosion, and other desired physical properties to the finished product. Commonly used aggregates include sand, crushed or broken stone, gravel (pebbles), broken blast-furnace slag, boiler ashes (clinkers), burned shale, and burned clay.
Aggregates for Concrete bination of gravels or crushed stone with particles predominantly larger than 5 mm (0.2 in.) and generally between 9.5 mm and 37.5 mm (3⁄ 8 in. and 11⁄ 2 in.). Some natural aggregate deposits, called pit-run gravel, consist of gravel and sand that can be readily used in concrete after minimal processing. Natural
Crushed stone is used as aggregate in construction material uses. The most common types of rock processed into crushed stone include limestone, dolomite, granite, and traprock. Smaller amounts of marble, slate, sandstone, quartzite, and volcanic cinder are also used as construction aggregates. Relation to Mining
In the aggregates industry, these rocks are classified as crushed stone, sand, gravel and slag. We use aggregates every day. Streets, bridges, roads and sidewalks are made of concrete or asphalt which is mostly made up of aggregates combined with a binder that acts like glue. Concrete is used in foundations and basements for houses. Know More

Building Material : Stone Types,Geological,Physical Classification Properties,requirements and Tests on Stones. This test is carried out on stones which are used as aggregates for road construction. The test result indicate the suitability of stones against the grinding action under traffic.
Stonedust, 7/8″ and 2″ Crushed Stone. Crushed Stone is great for packing since it is a mixture of various sized stone and stonedust. It is used under slabs, for driveways, or anything you need a good hard base. Crushed Stone is also known as gravel, granular A, 3/4″ crushed stone, and GA. Applications: Under patio stones; Interlocking brick
Why Stones/Gravel is used in electrical Switchyard Gravel/Stones in the substation is provided to reduce the step potential and touch potential when operators work on switch yard. 2. Power Transformers installed in the substations will have oil as cooling and insulating medium.
Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag, used with a hydraulic cementing medium to produce either concrete or mortar. Those particles that are predominantly retained on the 4.75 mm (No. 4) sieve, are called coarse aggregates. Those particles passing the
The resin bonded aggregates method involves applying the resin over a suitable base using a squeegee, and then 'scattering' the chosen gravel or aggregate over the tacky resin before it sets. Some systems use pre-coated aggregates, while others rely on applying a resin over the scattered stone to seal the system. What is resin bonding used for?
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.

30-10-2019Large Stones. Rocks ranging from three-eighths to three-fourths of an inch in size are perfect for artificial grass sub-base installations. The most common gravel materials used are crushed or decomposed granite, along with other aggregates.
The rigid surfaces allow the stones to be tamped, rolled or even vibrated into place until they lock and form a more stable surface, unlike when using a smooth surfaced material such as gravel. Crushed stone is a versatile material and can also be used for many commercial, residential and DIY projects.
