Crushed Stone Aggregate is a broad category of coarse 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. Crushed stone or Stone or angular rock is a construction aggregate. It is created by mining a suitable rock formation and then using a crusher to break down the stone into different sizes. Crushed stone differs from gravel in that gravel has a more rounded shape and is made by the natural processes of weathering and erosion. Crushed stone has continuously been used for a variety of construction needs because of its versatility. It is one of the most common and accessible natural resources on the planet. It is one of our most abundant and basic of raw materials.
Uses Of Stone Aggregates: Stones are used in various industries from construction to agriculture.
Their uses are:
Used in paving blocks and concrete for sidewalks, driveways, patios, homes, office buildings and paved roads as a base or subbase material or in the process of cement manufacture
Used as a flux in blast furnaces to create liquid slag which, when cooled, becomes a stone material that is crushed and used as a construction aggregate
Placed on the ground in landscapes around trees, drains and as tracking pads on construction sites
A road construction technique called Macadam uses stones in which the strength of the road depends upon the interlocking of the stones due to their angular shapes
Used with a binding material in walls for shorelines in order to protect against erosion from water or ice
Used in railroad construction
Used in sewage treatment systems
Used in the manufacture of agricultural lime
Types: Types of crushed stone are categorized by the size of the stone after it has been crushed.
