Influence Of Plasticizing Additives on The Physical and Mechanical Properties of Gypsum Materials

The article presents the results of studies conducted to study the effect of superplasticizers of the FREM S3 brand based on naphthalene-formaldehyde resin and the SZhZ-3 brand based on polycarboxylate ether on water demand, setting kinetics and strength of gypsum materials used in ceramic industry enterprises producing porcelain and earthenware and sanitary ware. It is noted that the positive effect of the SDZ-3 additive on the formation of the optimal structure and strength of the gypsum material is significantly higher than that of the FREM S3 additive.
