METHOD OF MAKING COMPOSITE CONSTRUCTION ARTICLE Russian patent published in 2013 - IPC B28B1/50 

FIELD: process engineering.

SUBSTANCE: invention relates to construction, namely, to method of fabricating composite construction articles. Proposed method comprises mixing concrete mix components with water and gas-forming additive, laying produced mix in mould to make structural layer of article, placing polystyrene pellets thereon to make heat-insulation layer, closing said mould by cover, placing moulded article in preheated curing room, curing at increased temperature, decreasing temperature and cooling of article. Moulded article is place in curing room preheated to 80-85°C to increase temperature therein to 95-100°C. Curing is carried out at increased temperature in two steps. At first step, curing is performed at 95-100°C for 0.5-0.7 h and, thereafter, temperature is decreased. At second step, curing is performed at 70-75°C for 4-5 h.

EFFECT: higher adhesion between structural and heat-insulation layers.
