The unit of the concrete mix proportions is in kg/m³.

Reference to [11, 34, 35, 36] can be made for more detailed descriptions of the concrete mixes.

1 Note:

GEPI is calculated per Equation (3) and is graphically visualised as the distance from the origin of coordinate system in Figure 1 and Figure 2.
