GIPS-ZEMENT-TROCKENMISCHUNG UND DARAUS HERGESTELLTE GEBÄUDEFERTIGTEILE
The invention relates to a gypsum-cement dry mix, the use thereof and a method for producing prefabricated construction parts using the gypsum-cement dry mix. For this purpose, the gypsum-cement dry mix comprises: a binder containing calcium sulphate hemihydrate or a mixture having at least 50 wt. % thereof and hydraulic cement in a weight ratio of 5:1 to 3:1; an aggregate material selected from crushed wood, plastic, expanded clay, perlites or a foam material or a mixture thereof; additives containing at least one plasticiser, at least one air-entraining agent, at least one stabiliser, and at least one delayer/accelerator, wherein the additives are present in dry form, and the mass fraction of the sum of all the additives in the total mass of the dry mix is <1%, wherein the stabiliser is selected from fluorophosphates or condensed phosphates, wherein the delayer is a water-soluble anionic polymer, and wherein the stabiliser-delayer mass ratio is 3:1 to 1:3.
