POUR MORTAR BASED ON BINARY ETTRINGITE BINDER CONTAINING AT LEAST ONE POLY (ALKYL OXIDE) COMBUM POLYMER AND AT LEAST ONE STRUCTURING ORGANIC RESIN
POUR MORTAR BASED ON BINARY ETTRINGITE BINDER CONTAINING AT LEAST ONE POLY (ALKYL OXIDE) COMBUM POLYMER AND AT LEAST ONE STRUCTURING ORGANIC RESIN
Dense mortar based on an ettringite binder (calcium sulfate/calcium aluminate) and an organic structuring resin also contains a polyalkylene oxide with a comb-like structure. Dense mortar containing (i) an ettringite binder comprising calcium sulfate and a mineral compound of calcium aluminates consisting of oxides of calcium (C) and aluminum (A), soluble and combined in one or more crystallised and/or amorphous mineralogical phases in which the effective mol ratio of C/A = 1.2-2.7 and the total weight of the phases (C + A) is at least 30 wt% of that of the mineral compound, (ii) polyalkylene oxide(s) with a comb-shaped polymer structure (PCP) and (iii) less than 2 wt% organic structuring resin(s).
