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.

What is the ratio for rubble concrete?

162. Comparison Of Quantities Of Materials - The mixture of concrete used for this class of work is often 1 part Portland cement, 3 parts sand, and 6 parts stone. The quantities of materials required for one yard of concrete (www. books.google.com) ("Cement and Concrete") 495. The concrete was one part Portland Cement; three parts sand; three parts gravel and three parts broken stone. (www.books.google.com) ("Cement and Concrete")

How is concrete made?

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.


How do you make concrete?

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.

What does concrete?

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.
