By default, the concrete mixture ratio of 1 part cement, 3 parts sand, and 3 parts aggregate would approximately produce 3000 psi of concrete mix. The right ratio of portland cement, sand, aggregate (stone), and water can create a strong and durable concrete mix. Given below concrete mix ratio formula to calculate the volume, cement, sharp sand, gravel and water. You can calculate the volume of concrete mix ratio or in different measurements such as mm3, ml, l, cm3 and so on.
Concrete mix ratio formula is derived for finding the volume. To do so, just find the product of width, height and depth. Similarly, for cement, multiply volume with 320. To find sharp sand, multiply volume with 600. For Gravel, multiply volume with 1200 and for water multiply volume with 176.
