### Concrete Mix Ratio: What Is It? What Is 1-2-3? And More

A concrete mix ratio is usually expressed by a set of numbers separated by colons as is the case with a 1:2:3 ratio. This tells the mixer that they need to add 1 part cement powder 2 parts sand and 3 parts aggregate in order to create the desired concrete consistency.### Mix Design and Calculation Chart - Boral
