Building materials based on silicates
Silicate materials find applications in many industries. They are used for example in the construction industry (concrete, cement, lime), the ceramics and glass industries (from classic cups and glasses to special applications such as catalyst supports or special filters), in paint industries (binders and fillers), fireproof and refractory applications (the lining of domestic fireplaces to large foundry and glass furnaces) or in the restoration of artworks.Our group is focused on a number of projects in the field of silicates. We offer to our customers except the classic tests of materials also consulting and an expert services.
Research group of building materials based on silicates carries out sample testing of construction materials to withstand high temperatures, pressures and aggressive environment.
For testing of building materials we have a top-class laboratory equipment and qualified professionals in the properties of silicate building materials.
