METHOD OF PRODUCING ELEMENTS OF LAMINAR GUARD STRUCTURES Russian patent published in 2011 - 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 adding disperse reinforcement made up of crushed alkali-resistant glass fiber in the zone of contact between structural and heat-insulation layers. After concrete of outer structural layer with mean density of 800-1400 kg/m³ and preset thickness is laid into form and compacted therein, crushed alkali-resistant 20-30 mm-long glass fiber is deposited thereon in amount of 0.04-0.06 kg per 1 m². Then, heat-insulation layer from concrete with density of 200-400 kg/m³ is laid in said form and subjected to vibration for 30-60 seconds. Thereafter, said form is filled with another jointing layer and structural layers are laid and subjected to vibration for 50-100 seconds.

EFFECT: higher strength and durability.
