Producing fiber-reinforced concrete

Mixing high-quality fiber reinforced concrete or shotcrete requires precise control over material dosing and weighing, concrete mix temperature and slump.

Tecwill_fiber_dosing_unit

For each concrete batch Tecwill's equipment ensures:

High-accuracy weighing with Tecwill's “flying” weighing system
Better aggregate moisture control with the Tecwill's OptiMoist system
Optimized control over concrete mix slump and temperature

The right solution for all fiber reinforced concrete applications

Fiber equipment

Fiber module Fiber module integrated into the batch plant The fiber module is seamlessly integrated into the batch plant for easy operation. It's build-in weather protection ensures fibers are protected from rain.

Automated fiber dosing system Fully automated dosing of steel, synthetic or polypropylene fibers

The fully automated "flying" weighing system doses steel and/or plastic fibers directly on top of the flowing aggregates, ensuring proper spreading and efficient premixing .

Fiber unit Fiber unit with multiple dosers and conveyor belt

When different types of fibers are used, the fiber unit can be delivered with several separate dosers.
Fibers can be fed into the plant mixer or directly to truck mixer drum.

Automatic fiber dispensing system

Any concrete batch plant can be equipped with an automatic fiber dosing system to precisely measure and dose the required amount of fiber into the concrete batch.

Typically, fibers are added to the ready-mixed concrete in a concrete mixer. Alternatively, a mixer bypass method dispenses the fibers directly into a truck mixer.

Our automatic fiber dispensing system includes:

A fiber dispenser with all needed accessories
A batch control system that accurately dispenses fibers according to mix design
Optional enclosure for winter operations

BENEFITS DOSING THE FIBERS WITH TECWILL'S “FLYING” AGGREGATE WEIGHING AND DOSING SYSTEM

The Tecwill “flying” aggregate weighing and dosing system allows fibers to be dosed at the same time as aggregates. Fibers are added to the moving aggregate flow, where they are pre-mixed with the aggregates. This approach provides many advantages over other systems, including:

Shorter mixing time because fibers have been pre-mixed with the aggregates
Reduced mixer wear due to shorter mixing times
Better concrete quality because of the homogenous distribution of fibers
No fiber clumps in the concrete
Fewer problems with shotcrete spraying machines
Improved tunnel lining quality

Polypropylene fiber dosing system

Polypropylene (PP) fibers are widely used in shotcrete and concrete floors. Because they are very light, they require a special dosing system. Our solutions for PP fibers include:

Manual dosing system for 1, 2 or 5 kg fiber bags
Fully automatic bag dispenser system for bagged fibers
Fully automatic dispenser system for loose fibers

Color dosing system

Color pigments in either liquid or powder form can be added to concrete. Each for requires a specialized dosing system.
Our liquid dosing system consists of storage tanks, pumps, scales and pipelines. We can deliver 1 to 6 color tanks for each plant, depending on customer requirements.

Powder pigments are dosed either as powder or granules, depending on the application. Both forms are dosed using a screw conveyor (auger) from the super bag storage bin to the scale.

The measured batch is then transferred from the scale to the mixer by a pneumatic conveying system. The dosing process is integrated with the control system for automatic operation.
