Production of non-metalic building elements and materials

Cable channels

Cable channels UNI 121 are made from glass-fibre reinforced concrete (GFRC). They are offered as elements of compact building system. Cable channels UNI 121 are intended for placing of electric cables including high-voltage lines, for example in underground tunnels or in railway tunnels.

Complete system of GFRC channels for railways includes light-weight, easy installable channels, for placing on ground and also for hanging in cantilevers, for example for installation on bridges etc. Together with accessories - T-shapes, arches, lids, cantilevers etc. forms compact system for placing of electric cables.

UNICRET

Fine-grained concrete reinforced by alcali-resistant glass fibres is supplied under the trade name UNICRET. Progressive technology affects strength characteristics of UNICRET and provides high impact strength. The main advantage of UNICRET products in comparison with the products made from floated concrete is small thickness and low weight, which affects favourably transport costs, manipulation and assembly costs.

Production of special lime

Lime for special purposes

Lime for special purposes is produced in the kiln line of the Research Institute of Building Materials in Brno. Typical characteristics:
Content of free (active) CaO in lime min. 95 %
Lime activity (reaction speed) min. 75 °C to 1 minute

Hydraulic lime

It is produced on the production line of the Research Institute of Building Materials in Brno. It is used for building purposes, especially at repairs of sights. It is produced with other components. Adjustment of properties and composition is possible in accordance with consumer requirements.

Viennese lime

Viennese lime is used for the production of grinding paste usable mainly in the engineering industry. It is produced by hard burning of crushed and very clear dolomite in a rotary kiln in the Research Institute of Building Materials in Brno.
