Glass fibre reinforced concrete Hentschke fibre+

Hentschke Bau GmbH

Description

On the basis of a building supervisory approval in individual cases (ZiE), Hentschke Bau GmbH installs concrete façades consisting of only 30 mm thick glass fibre reinforced concrete elements. The envisaged general building authority approval will allow for even further reduced wall thicknesses. 3D façade elements made of glass fibre reinforced concrete (GFB) for curtain walls (VHF) offer very individual and unmistakable design opportunities for the façade. Folded, curved and free-form façade elements can also be produced, offering architects new possibilities in façade design with concrete. Glass fibre reinforced concrete elements are also very interesting for interior design (building material class A1, non-combustible).

We will be happy to advise you in detail on the feasibility of your ideas for geometries, surfaces, colours and effects .

More Over

Hentschke

fibre+ is a glass fibre reinforced concrete with alkali-resistant glass fibres approved by the building authorities, aggregates for a separate grading curve and various additives.

General construction description

The glass fibre reinforced concrete elements are designed with solid walls or reduced mass. The static requirements are taken into account by geometric design and selection of the appropriate concrete recipe. If necessary, additional reinforcement is made of suitable materials. The fastening is concealed by molded-in sleeve dowels. The manufacturing process enables element production within narrow tolerance ranges.

Typical material characteristics

The maximum dimensions are determined by component shape, material thickness, location of the attachment points and load (project-related technical solutions).

Execution

The project-related specification is determined on the basis of a sampling. Concrete is a natural material, and this will also be shown. Complete colour uniformity and homogeneity of the surface cannot be guaranteed, but this is what makes a concrete surface lively. In the case of grey cements and colour pigments, natural cloudiness is characteristic and cannot be avoided with technical accuracy.

Surface

The surface of the glass fibre reinforced concrete elements is smooth as formwork and virtually free of pores. On request, surfaces can be processed or structured almost arbitrarily with matrices.

Structural formliners Structural formliners

are textured inserts for structuring peeled concrete surfaces. They enable easy-to-manufacture yet very sophisticated surfaces in a wide variety of designs.  

Surface treatment

Surface treatments such as washing, acidifying, sanding or blasting bring out the beauty of the natural stone grain . Processed surfaces often reproduce colours differently and under the influence of light, interesting effects of the exposed aggregates can be created.

Colour

The colour of the basic recipe is either white or grey. A wide variety of colourings are achieved through colour pigments. The desired colours are produced individually on a project-by-project basis.

Edge formation

The standard variant of edge formation is a perfect "sharp" edge (radius of approx. 3 mm). This creates perfect burr- and chip-free, but at the same time robust edges. Moulded mouldings enable classic broken edges and project-specific solutions are also developed.

Hydrophobic and graffiti protection

A range of different surface protection systems is available to protect against environmental influences and pollution. The systems are usually colorless, permeable and breathable. A distinction is made between matt and glossy hydrophobic coatings and anti-graffiti coatings. While matt systems underline the naturalness of the material, a gloss level visibly influences the appearance of the surface and the brilliance of the colour.

Safety information

The Hentschke fibre+ product is harmless to health and fully recyclable when cured.

Processing on the construction site

Recesses and cut-outs can be made as far as possible during production. When processing on site, protective goggles and ear protection must be worn when cutting and drilling, and additional face masks must be worn when dry cutting.
