Abstract
La présente invention concerne de nouvelles utilisation du gypse rouge, un sous-produit de la production du dioxyde de titane qui contient entre 60 et 90 % de CaSO4.2H2O; 3 à 35 % d'oxydes/hydroxydes ferreux et ferriques représentés comme un groupe Fe(OH)3; 0,3 à 2 % de TiO2; 0,1 à 4 % de SiO2; 0,1 à 0,8 % de Na2O; 0,1 à 5 % de CaCO3; 0,1 à 0,4 % de MgO; 0,1 à 0,2 % de potassium, calculé sous la forme K2O; et 0,1 à 0,2 % de phosphoreux, calculé sous la forme P2O5. Nous avons trouvé que l'adjonction de gypse rouge aux sols rigidifie et renforce les sols. L'invention concerne dont des mélanges de sols stabilisés comprenant du gypse rouge. L'invention concerne également des compositions cimentaires intégrant du gypse rouge, une source de silicates d'alumines telles que l'argile, les cendres volantes, ou le laitier broyé, et de la chaux. Les compositions cimentaires de l'invention, qui ne sont sensiblement pas anhydres comme le Portland ordinaire, mais au contraire, contiennent des quantités notables d'eau, font étonnamment preuve de qualités rhéologiques comparables à celles du Portland. Il semble que des composants secondaires, présents de façon inhérente dans le gypse rouge, soient à l'origine des surprenantes qualités rhéologiques des ciments hydratés de l'invention.
