FIELD: construction.
SUBSTANCE: invention relates to production of non-toxic plates based on mineral binder and they can be applied to making heat insulation and finishing materials used in construction of residential and industrial premises. Reinforced gypsum-modified mineral plate comprises composite structural material, presented in form of rigid molded web consisting of gypsum, fine expanded clay, and structure forming gypsum-modifying binder, wherein plate is reinforced with glass mesh and additionally at one side - with glass fibre canvas; plate is selected with following ratio, wt.%: gypsum G-5 BII 65-80, MG-2 (gypsum modifier) 15-20, expanded clay 4-13, polycarboxylate plasticiser 0.3-0.9, antifoaming agent 0.2-0.5, fibre 0.5-0.6.
EFFECT: production of heat insulation and finishing materials used in construction of residential and industrial premises.
