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.
Crushed marble stone has a low absorption rate hence less water is required which means better strength. Also the marble typically has a denser specific gravity.
The Romans made their roads using layers of different sized rocks. Their roads were very strong and durable. Some still exist today.

Marble and other similar substances are mineral resources, and form a class of materials called dimension stone. This business is similar to the aggregates and crushed stone industries.
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.

Crushed stone density is variable ranging from 2.4 - 2.7 Metric Tons per cubic Meter depending on the type of stone, the stone crushing machinery, and how the crushed stone is sorted after crushing.
