The concentration dependence of the inhibitory effect of mono-, di-, tri- and tetrasodium salts of ethylenediaminetetraacetic acid (EDTA) on the gypsum curing process has been studied. The activity of these salts has been compared with sodium trisubstituted citrate, which is widely used as a curing retarder in commercially available gypsum formulations. It is shown that the disodium salt of EDTA has the greatest retadant activity of the studied salts. The optimal concentration range of working s
