CONSTRUCTION EXTRUSION-COMPENSATORY BLOCK, BLOCK PRODUCTION LINE AND METHOD FOR POROUS MATERIAL PRODUCTION FOR BLOCK FILLING Russian patent published in 2008 - IPC E04C1/00 

FIELD: construction, particularly building elements of block or other shape for the construction of parts of buildings.

SUBSTANCE: construction block comprises shell of solid sand concrete and core made of porous cement-based material. Block is produced by extrusion-compensatory method with shell cavity division into three sections by means of transversal stiffening diaphragms. The sections are shaped as triangular prisms. Solid sand concrete includes sand having gradation factor of at least 1.88. To provide cement-sand concrete plasticity during block forming tall oil pitch taken in amount of 0.3-1.5% of Portland cement mass is additionally used. Raw mix for porous material preparation includes (per 1m³ of ready mix) Portland cement - 159-300 kg, tall oil pitch - 0.9 l and aqueous protein solution with 0.75-0.9% concentration - 3.2-6.0 l. Shell and stiffening diaphragms of construction block have the same thicknesses. Shell production method and method for porous material production for shell filling are also disclosed.

EFFECT: increased quality and productivity.
