CHTT patented system

GREEN TECHNOLOGY FOR THE PRODUCTION OF QUALITY CONCRETE

 WHAT THE CHTT SYSTEM IS?

The CHTT (Concrete High-Tech Turbomixer) is a system for the production of the Cement Paste.

The Cement Paste is obtained mixing the cement, the water and the additives.
The CHTT prepares the cement paste and discharges it into the stazionary mixer or Truck Mixer .
The stazionary mixer or Truck Mixer completes the mixing of the cement paste with the aggregates.
The cement paste feeding into the stazionary mixer or Truck Mixer is made in such a way to obtain a perfect distribution of the cement paste in the bulk of the aggregates, thus obtaining a homogenous concrete.

The innovative Mixing system is based on a special Mixer for the preparation, in one batch only, of a Mixture composed of water, additive and cement which is fed into the Truck Mixer in a proportional and simultaneous way to the aggregate.

The cement paste quantity which can be produced with the CHTT in one single batch is sufficient to load a 12 m3 Truck Mixer.

All the system is controlled with a PC with Dedicated Software

WHY USE THE CHTT SYSTEM?

For the QUALITY of the concrete due to the perfect mixing of the components.

The recipe being equal, the workability and the mechanical characteristics of the concrete made with CHTT sensibly increase.
For the ECONOMY of the concrete production costs.
The optimization of each phase of the production process results in a sensible economic advantage for the producer.
For the very high PRODUCTIVITY; the system can load a 12 m3 Truck Mixer in one batch only.
For the LOW ENERGETIC CONSUMPTION in respect to the traditional mixers (Twin Shaft or Planetary); the electric absorption is reduced approximately to one fifth.
For the EASE of installation even on the existing plants, it does not require any structural modification to the Concrete Batching Plant.

ALL THE ADVANTAGES OF THE CHTT
Real saving of the cement due to the bigger workability, the water quantity being equal.
Bigger resistance and workability, the concrete recipe being equal.
Perfect Mixing of the components and increased homogeneity of the concrete.
Optimization of the admixture performances due to the forced mixing of water and cement.
Better pumpability of the concrete, the fine parts being equal.
Ideal for the production of self-compacting concrete(SCC).
Low Electricity Consumption (0,5 KWh per cubic meter of produced concrete).

Wears and maintenance costs almost nonexistent.

Drastic Reduction of the cement dust emissions at the Truck Mixer loading point.
Less wears of Truck Mixer and Concrete Pumps.
Reduction of the Truck Mixer washing time and of the water consumption.
High productivity with 12 m3 Truck Mixer load in just one batch.
No structural modification of the concrete batching plant is requested (installation on the ground).
Possibility of producing homogeneous coloured concrete.




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)
