The authors have developed modified foamed gypsum which meets safety and environmental requirements. Pore formation of gypsum matrix is made using protein frother UFapor. It belongs to protein group, that provides environmental purity and fire safety of gypsum products and constructions. The influence of the water firm relation, the amount of frother and a plasticizing additive on properties of hardened foamed gypsum material is investigated. Сreation of the modified foamed gypsum which respond safety and environmental requirements were investigated. The optimum amount of frother is defined according to the research results. The authors have determined that introduction of additive Melflux 1461f reduces water demand of the mixture and improves physical and mechanical properties of the modified gypsum block. Foamed gypsum possesses physical and mechanical properties that are enough to receive architectural elements and finishing materials.
