The ratio of cement to sand and gravel typically depends on the type of concrete mixture being prepared. For a typical concrete mixture, the ratio should be 1 part cement, 2 parts sand, and 4 parts gravel. However, this ratio can be modified depending on the type of concrete mixture being prepared. For instance, a mixture used for driveways or ...

The median grain size ratio (D 50 /d 50) is the ratio between the median grain size of the gravel particles and the median grain size of the formation sand particles. When D 50 /d 50 reaches the optimal value, the gravel pack can meet the requirements of both a better sand control ability and a better performance for fluid flow.

Given : A mixture contain sand and gravel in the ratio 1:4 . Let the weight of sand is x and the weight of gravel is 4x. Since, the total mixture weighs 10kg, then x+4x=10. i.e. 5x=10 ⇒ x=2. ∴ The weight of sand = x= 2 kg. Also, the sand has 20% impurity, then the weight of impurities = 20% of ( weight of sand) [∵ 1 kg = 1000 g]
