RAW MIX FOR PRODUCING CONSTRUCTIONAL MATERIALS AND ARTICLES

摘要

The invention can be used for producing multipurpose constructional materials and articles from raw mixes containing foamed vermiculite in the form of an aggregate. Said invention makes it possible to increase the physico-mechanical and heat insulation properties of the produced materials and articles and to reduce the weight loads applied to structural elements of buildings and constructions. The inventive raw mix comprises cement, foamed vermiculite, a mineral batch and water. The mineral batch is embodied in the form of a dry mix consisting of one or two materials which are selected form a first group comprising sand, expended clay and broken stone, and one or two materials selected from a second group comprising powder lime, gypsum and clay. In a two-component batch, weight fractions are equal to 1.o and 0.1-1.5, respectively. In a three-component batch, the weight fractions are equal to 0.95-0.05, 0.05-0.95 and 0.1-1.5 or 1.0, 1.9-0.1 and 0.1-1.9, respectively. In a four-component batch, the weight fractions are equal to 0.95-0.1, 0.95-0.05, 1.9-0.1 and 0.1-1.9, respectively. The mix has the following component ratio: 8-25 mass% cement, 5-21 mass% foamed vermiculite and 13-42 mass% mineral batch, the rest being water.
