FIELD: construction engineering. SUBSTANCE: these slabs perform load-bearing, noise-protecting and heat-conserving functions in flooring and covering structures of low-storey dwelling and agricultural buildings. Composite arbolite slab has prestressed longitudinal reinforcement, arbolite layer and concrete layers. Arbolite layer is made of porous arbolite. Concrete layers are located on end faces of arbolite layer in perpendicular to plane of reinforcement tensioning. EFFECT: high efficiency. 3 dwg
