    For a less reactive type of cement the effect of the gypsum-hemihydrate ratio was not so pronounced but for the lowest ratio of 20/80 a false set was observed. In the presence of a melamine-based superplasticizer an even more pronounced effect of the gypsum-hemihydrate ratio on the rheological properties of the fresh concrete was observed.
