Crushed stone aggregates are called so because they are formed by mechanically breaking down larger rocks into smaller pieces, or aggregates. This process results in various sizes of stone fragments that can be used in construction and landscaping. The term "aggregate" refers to a collection of items that can be combined, and in this context, it indicates the material's role as a fundamental building block in concrete, asphalt, and other construction applications.
Sand and gravels are naturally occurring, in pits, while crushed rock is a product of blasting and crushing rock, in a quarry.
Pouring a concrete sidewalk without a layer of crushed stone is not recommended. Crushed stone provides essential drainage, helps prevent moisture buildup, and creates a stable base that reduces the risk of cracking or settling over time. Without it, the concrete may be more susceptible to damage from water and temperature fluctuations. For best results, always include a proper base layer of crushed stone.

In an electrical substation, crushed stone is typically preferred over washed natural gravel for several reasons. Crushed stone provides better drainage and stability, helping to prevent erosion and ensuring that the ground remains level and well-drained. Additionally, its angular shape allows for better interlocking and compaction, which is important for supporting heavy equipment and electrical infrastructure. Overall, crushed stone enhances safety and reliability in substation operations.
Crushed stone or angular rock is a form of construction aggregate, typically produced by mining a suitable rock deposit and breaking the removed rock down to the desired size using crushers. Most crushed stone is used in highway construction and building construction. Mantra Minerals are the leading Crushed stone suppliers in india offering the best quality crushed stones in India.

Raw materials that are a component in concrete, aggregates are inert granular materials such as sand, gravel or crushed stone. Coarse aggregates are particles greater than 4.75mm, but they generally range between 9.5mm to 37.5mm in diameter. Primary coarse aggregates come from the land or water. Secondary aggregates are the by-products of extractive operations. The third source coarse aggregates come from is recycled aggregate, which is sand, and recycled concrete aggregate.
Plain cement concrete is primarily composed of three key materials: cement, aggregates, and water. The cement acts as a binding agent, while aggregates, which include fine aggregates (like sand) and coarse aggregates (like gravel or crushed stone), provide bulk and strength. The water facilitates the chemical reaction that allows the cement to harden and bind the aggregates together. Typically, the mix ratio can vary, but a common formulation is 1 part cement, 2 parts sand, and 4 parts coarse aggregates by volume.
No, concrete is not organic. It is made from a mixture of cement, water, and aggregates such as sand, gravel, or crushed stone. Organic materials come from living organisms, while concrete is a man-made product.

The density of 13mm crushed stone can vary depending on the type of stone and the compaction of the material. On average, 13mm crushed stone typically has a density of around 1.5 - 2.0 g/cm3.
Crushed stones are typically referred to as crushed stone or crushed rock. These crushed fragments are commonly used in construction and landscaping for a variety of purposes such as making concrete, paving driveways, and drainage applications.

Aggregate is the general name for a mixture of crushed stone, gravel, and sand.
The construction industry uses the most crushed stone. It is a key ingredient in concrete, asphalt, and road construction, as well as for building foundations and railroad ballast.
The Romans in 127 AD used crushed pumice for aggregates in cement (light weight concrete) for walls of Pantheon in Rome
