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.
Concrete is made from cement and other cementitious materials such as fly ash and slag cement, coarse aggregate made of crushed stone, fine aggregate such as sand, water, and chemical admixtures. For more information please visit the related link.

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.
If by aggregate you mean the 'rock' mixed in to make concrete, then the density is usually about 2.7 g/cm3 .
The ratio of cement, sand and crushed stone in M 25 grade concrete is 1:1:2.In this grade of concrete a compressive strength not less than 25 N/mm2 is achieved in 28 days.
Basalt can be crushed into crushed stone (aggregate), and used as a material in making concrete or asphalt paving.

Concrete is a well proportioned mixture of cement and other cementitious materials such as fly ash and slag cement, coarse aggregate made of crushed stone, fine aggregate such as sand, water, and chemical admixtures. The more inclusive answer is that concrete is a matrix of stone/sand aggregate adhered into a mass with a binding agent like Portland Cement or hot asphalt oil. This can refer to a person: He was as solid as concrete and would not move off his position.

Aggregate is the gravel or stone in the concrete. It is what gives concrete it's strength. Think of the aggregate as the bricks of a wall and the concrete and sand as the mortar.
