FIELD: building.
SUBSTANCE: invention concerns area of manufacturing of building materials, and can be used for manufacture of a version of foam mortar - porous concrete. Compound for porous concrete obtaining contains in quality of gasifier-cellulating agent - mix obtained by a joint grinding to 10 microns, following structure, wt %: aluminium powder 10-60, calcareous flour 39.99, sodium sulfonate - the rest, at following parity of components, wt %: cement - 51, thermal power station fly ash-27, specified cellulating agent - 0.3, water - the rest. Method of obtaining of porous concrete includes preparation specified above compound by hashing of cement, fly ash of thermal power station and water in a mixer with number of turns from 1000 rpm during 1 minute with the subsequent introduction of the specified cellulating agent at hashing during 30 seconds and pouring of the obtained mix in forms, its buckling and hardening.
EFFECT: porous concrete improvement of quality, increase in period of storage of dry cellulating agent.
