  • Cement and calcium sulfate based binder composition
    Patent number: 9815740
    Abstract: The invention concerns a composition containing a) 2 to 80 weight % of Ordinary Portland Cement with respect to the total weight of the composition b) 2 to 80 weight % of a calcium sulfate based binder with respect to the total weight of the composition, with the proviso that the weight ratio of a) Ordinary Portland Cement to b) calcium sulfate based binder is from 95/5 to 5/95 and c) at least one retarder for calcium sulfate based binders, the retarder being a chemical structure, which comprises from 3 to 70 amino acids. Also concerned is the use of the compositions for self-levelling underlayments, tile adhesives, non-shrink grouts, floor screeds and repair mortars.
