After mining, aggregates are subjected to different weather changes and storage conditions. Under these conditions it is very difficult to automatically control the contribution of arid weights and water to concrete, which are affected by concepts such as homogeneity and volume. The solution to these problems is achieved by means of correction on the basis of moisture contained in the materials. Two basic corrections enable the following:

- Auto correction of kilos in the dosage process that maintains the aggregates / cement ratio (constant volume)

- Calculation of the water contribution from the afore-mentioned dosage (water / cement ratio) to provide the desired strength and plasticity.
