Grades of Concrete for Foundations, Slabs, Columns, and
Up to M25, a nominal mix can be made for small-scale construction where concrete consumption is not high. For M 30 and above grades, Design Mix should be used. You can see that as the strength of concrete increases, the cement content is constant in proportion but sand, aggregate, and water content are reduced. Get price

Properties of concrete
Concrete has relatively high compressive strength (it doesn't crack under weight), but significantly lower tensile strength (it cracks when being pulled). The compressive strength is typically controlled with the ratio of water to cement when forming the concrete, and tensile strength is increased by additives, typically steel, to create reinforced concrete.
