Emergency response (+34) 689 647 910 HOME PRODUCTS ABOUT US CSR CONTACT ENG Applications HOME · CONSTRUCTION MATERIALS APPLICATIONS Construction Materials The use of fluorides such as dry calcium fluoride and anhydrite is widespread in various construction materials such as cement or ceramics. However, there are other applications for our products in which fluorine plays an important role and is used as an additive. DDF’s production includes synthetic calcium sulphate, a substance used for the production of self-levelling screeds which our company provides in several forms, from basic crushed anhydrite to micronised and packaged products. Would you like more detailed information on our products for the construction industry? Are you interested in starting a certification process for any of our products?
