摘要
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).
