TECHNOLOGY TO MANUFACTURE FOAM CONCRETE MASS, ARTICLES, PARTS AND MEMBERS AND GEAR FOR ITS IMPLEMENTATION Russian patent published in 2003 - IPC

FIELD: building materials and articles. SUBSTANCE: salient feature of invention consists in layer-by-layer pouring of foam concrete mixture and sealing of separable edge attachments prior to their heat and humidity treatment with use of sealing coat of edge attachments of lower layer as base for edge attachments of above-lying layer. Height of layer is chosen by formula h = τ₀/ρ, where τ₀ is ultimate stress of shear of prepared foam concrete mixture; ρ is average density of mentioned-above mixture in ranges of 0.3-2.4 kPa and 200.0-800.0 kg/cu m. Number of mentioned layers is two as minimum. Temperature for heat and humidity treatment is started to grow with ultimate stress of shear of foam concrete mixture after preliminary curing in range of 2.0-10.0 kPa and hydration degree of cement in the latter not less than 2.5% by mass. Gear for implementation of technology is multilayer stack form with heat exchange elements fitted in side and horizontal plates of bases and pavements and separable edge attachments installed between the latter in the form of facet structure placed in each layer of specified form. EFFECT: reduced time and energy consumption for heat and humidity treatment, decreased cost of foam concrete and of dwelling in the long run. 15 cl, 2 dwg, 1 tbl
