Construction chemistry sand: silica sand as filler for construction
Our silica sands are the basic raw material used in construction chemistry for adhesive systems, levelling pastes and filling compounds, joint and special mortars, renders and coatings bound with cement and synthetic resin, and for products used for concrete restoration and building protection. Due to their constant brightness, our fine construction chemistry sands are outstandingly well suited as filler for producing joint and filling compounds.
Furthermore, our many years of experience in classification processes allows us to produce the finest silica sands without grinding, which represents both an economical and ecological alternative to silica flours in formulations.
Detailed manufacturing controls guarantee that the high requirements regarding uniformity in grain distribution, colour consistency and near-size grain are always met. External monitoring and CE certification in accordance with DIN EN ISO 12620 and 13139 take place annually.
