METHOD OF PRODUCING ELEMENTS OF LAMINAR GUARD STRUCTURES Russian patent published in 2012 - IPC B28B1/87 

FIELD: process engineering.

SUBSTANCE: invention relates to construction, in particular, to production of elements of laminar guard structures with heat-insulation layer from light concretes. Proposed method comprises pre-filling of moulds by concrete mixes of heat insulating and structural layers. With first structural layer with mean density of 800-1400 kg/m³ laid, reinforced contact layer is inserted therein formed by applying steel fiber on lower structural layer in amount of 0.4-0.7 kg 1 m², said fiber being 20-60 mm-long and having diameter of 0.3-1.0 mm. Then, concrete mix of heat-insulation layer with mean density of 200-400 kg/m³ is fed into mould to be vibrated for 30-60 s. Then, said mould is filled with the next bonding layer. In some 40-60 minutes the mould is filled with structural layer and vibrated for 50-100 s.

EFFECT: higher strength and durability.
