<p>The invention relates to the building industry, in particular to the production of parts which are usable in the construction of buildings and structures, including bricks, blocks, lintels for window spans and door openings, etc. A building material is proposed that is produced by mixing a mixture of caustic magnesite and expanded vermiculite having a bulk density of 90 to 250 kg/m3 with an effective amount of an aqueous magnesium chloride solution having a density of 1120-1290 kg/m3, wherein the amount of expanded vermiculite is 38.4-217 kg per 1 m3, the amount of caustic magnesite is 128-217 kg per 1 m3 and the volumetric ratio of caustic magnesite and expanded vermiculite is 1:3-1:5. The technical result is an expansion of the range of materials for load-bearing building constructions, which materials surpass known materials on the basis of a magnesian binder with fillers, in combination with characteristics such as specific mass, strength, heat conductivity, sound insulation and a semi-absorption cross section for gamma and X-ray radiation.</p> |
