FIELD: construction.
SUBSTANCE: multilayer building block comprises a decorative layer, a central layer arranged between an inner and outer structural layers made of ceramsite-concrete mix. The mix to make the central layer contains the following components, per 1 m3 of the mix: ceramsite gravel of 8÷22 mm fraction with apparent density of 350÷450 kg/m3 in volume of 1 m3; portland cement 130÷440 kg, polyvinyl acetate glue in volume of 1.3÷4.7 l, water in volume of 115÷125 l. The method is characterised to manufacture the multilayer building block.
EFFECT: increased strength of the block and simplified method of its manufacturing.
