The work describes the principles of low-energy technology of non-autoclave porous concrete (NAPC) based on fuel ash. After closing with water and mixing in a conventional mixer, the feed mixture is poured into molds or formwork, where it swells and then solidifies under normal conditions or with little heat treatment. The use of NAPC with the same average density as conventional light concretes on roasting aggregates for reinforced bearing structures can be justified by the close values of the total porous steel and the associated elastic and deformative properties, as well as similar working conditions of reinforcement in these products. At the same time, compared to gas-ozone concrete, NAPC is advantageously characterized by greater stability of properties during manufacture, lower consumption of ha-z-forming additives, and compared to conventional light concrete — the absence of expensive large porous aggregates. Strength and deformation characteristics of NAPC are determined both at short-term and long-term active loads, which is the basis for further research on the use of this per -special material in bearing and enclosing structures.
