Modified gypsum binder
Clay gypsum has properties similar to gypsum binder and can be used as gypsum compositions or solutions. The results of the study of the dynamics of thermal dehydration of gypsum binder, the study of the properties of modified clay gypsum without additives, with the addition of a superplasticizer and with the addition of a setting retarder are presented. The results are satisfactory in all cases. The highest degree of hydration is estimated by the heat release kinetics of the binder with the addition of a superplasticizer. The use of retarders slightly reduces the maximum degree of hydration and increases the hydration time. The degree of hydration of the binder with the addition of the C3 additive and the moderator is observed higher than that of the clay-gypsum modified binder, with clay without additives. Studies confirm the possibility of using a gypsum binder.
