TECHNICAL AND ECONOMICAL EFFICIENCY OF GYPSUM-CONTAINING COMPOSITES WITH THE USE OF VOLCANIC ROCKS
The author proposes raw mix for production of gypsum tuffcrete that helps to decrease specific expenses of gypsum bonder by 30,5…31,7 % not reducing gypsum concrete stability. Effective heat and fire protective gypsum vermiculite tuffcrete and cement vermiculite tuffcrete are developed. The research results of fire protective characteristics of two-layer ferro-cement elements with the use of suggested composition are given in the article. Technical and economical comparison of dividing walls and heat and fire protective plaster with the use of gypsum containing composites is carried out.
