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.

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.
Look up concrete in Wikipedia for detailed information. Concrete for a foundation or floor is generally mixed in the proportion 1 part cement, 2 parts sand, and 4 parts gravel (or crushed stone). Crushed stone is better than water worn stone as its irregular shape makes for stronger concrete. If a bag of cement is approximately 1 cu. ft., a 1:2:4 mixture calls requires 1 bag cement, 2 cu. ft. sand and 4 cu. ft. stone Since the sand and cement fills the voids of the stone the above quantities yield 4½ cu. ft. concrete. The concrete mixture is mixed, by hand with a shovel or in a portable powered concrete mixer, with water just sufficient to provide a workable mixture for the work in hand. Care is needed not to use too much water as this weakens the final concrete.
The recommended mix ratio for Portland cement in concrete is 1 part cement, 2 parts sand, and 3 parts gravel or crushed stone. This ratio helps to achieve optimal strength and durability in the concrete.

The recommended cement mix ratio for a strong and durable concrete structure is typically 1 part cement, 2 parts sand, and 3 parts gravel or crushed stone. This ratio helps ensure the concrete has the right balance of strength and durability for construction projects.
To mix concrete effectively for a strong and durable construction project, use a ratio of 1 part cement, 2 parts sand, and 3 parts gravel or crushed stone. This balanced mix will ensure proper strength and durability for your project.
Cement, sand and stone is what concrete is made of. Cement is the binding agent.
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.

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.
