The advantages found after 2 years of operation of the system are:
Actual saving of cement, in respect to the better workability with equal quantity of water.
Major resistance and workability with equal formula in respect to direct loading into the truck-mixer.
Perfect mixing of the components and increase of homogeneity in concrete.
Optimization in performance of ad-mixtures thanks to forced mixing with cement and water.
Better pumpability of the concrete with same contents of fine parts.
Ideal for the production of self-compacting concretes (SCC)
Total elimination of cement dust emission at the truck-mixer loading point.
Minor wear of the truck-mixers and of the pumps.
Reduction of washing time of truck-mixers and water consumption.
High production capacity: truck-mixer loading up to 12 cu.m. in a single cycle.
No structural change to the batching plant (ground installation)
