Fröschl Beton Tyrol
Fröschl Beton GmbH & Co KG operates a ready-mix concrete plant in the Innsbruck Rossau district, which has been producing concrete for construction sites in Innsbruck and the surrounding area since 1974. The plant produces ready-mix concrete and special concrete in every required strength class. The raw materials are aggregates (gravel and sand), cement and water; additives such as fly ash or colour pigments as well as admixtures such as superplasticizers allow targeted adjustment of appearance and technical properties. Production takes place via a digitally controlled tower plant with a double-shaft mixer and pan mixer, in operation since 2019, which achieves a maximum hourly output of 160 m³ with 2.5 m³ mixing capacity per batch. Fresh concrete is delivered to the construction site with the company's own concrete mixer trucks; self-collectors benefit from fast parallel loading. Concrete residues and return water are processed in a recycling plant and returned to the production process. An in-house laboratory monitors the quality of every batch and of the delivered raw materials.

Raw materials and concrete types
Ready-mix concrete
Industrially produced fresh concrete that is delivered directly to the construction site with concrete mixer trucks.
Special concrete
Concrete with adapted properties and strength classes for special requirements.
Cement
Binder of the concrete mix, stored in the company's own cement silos.
Gravel and sand
Aggregates as the main component, stored in the star-shaped segmented main silo.
Fly ash
Additive for targeted influencing of concrete properties.
Colour pigments
Additive for colouring and individual design of the concrete.
Superplasticizers
Admixtures for improving flowability and workability.

Additional services
Quality control
An in-house laboratory tests every concrete batch: after curing, specimens are subjected to a concrete strength and compressive strength test. The delivered raw materials gravel, sand and cement are also checked by the laboratory upon delivery.

Company history
- 1974
Construction of the concrete plant in Innsbruck Rossau to support the construction projects of the 1976 Winter Olympics.
- 2018
On 9 November, the old plant produced its last concrete batch; subsequently demolition including dismantling of the approximately 100-tonne aggregate silo with two mobile cranes.
- 2019
In early February, lifting of the new 135-tonne material silo with a 750-tonne mobile crane; in mid-March, the new concrete mixing plant type IV-600 went into operation.
