The effect of plasticizing additives on melamine formaldehyde (Melment F 15 G) and polycarboxylate base (Melflux 5581 F, Sika ViscoCrete-G2) on the properties of molding gypsum, consisting of ?-calcium sulfate hemihydrate, was investigated. Based on the results of the work carried out, the concentrations of additives were determined, allowing to increase the compressive strength of specimens from molding gypsum by 1.5 - mdash; 2 times
