Concrete: Batching and Mixing | Concrete Technology

In this system of batching, the materials are measured by volume. The gauging of cement by volume is most inadvisable as it is difficult to secure accuracy in its measurement as the actual volume of a given weight of cement depends upon how it is filled into a gauge box and whether it is shaken down.

A suitable gauge box or similar is therefore needed. The figures assume a general bulking factor for the materials and does not take into account any water in the sand or aggregate. Water should be added to obtain a workable but non-segregating mix, the total free water being roughly 170 litres per cubic metre of concrete.
