M 20 is the grade of concrete which ratio is 1 ratio 15 ratio 3 okay one is cement and 15 is sand and 3 is aggregate assume that we will find the materials calculation for 1 cubic meter
Proportioning of concrete is the process of selecting quantity of cement sand coarse aggregate and water in concrete to obtain desired strength and quality the proportions of coarse aggregate cement and water should be such that the resulting concrete has the following properties when concrete is fresh it should have enough workability so that it can
Ratio of cement sand and aggregate in concrete m25 ratio of cement aggregate sand in m45 m25 m10 calculate cement sand and aggregate civil rnd following is a simple method used by engineers to calculate cement sand and aggregate to produce different grade of concrete
