Claims (3)

1. The method of autoclaveless manufacturing of aerated concrete building products, comprising preparing a concrete mixture in a mortar mixer by mixing a binder, aggregate and water, followed by introducing a blowing agent into the mixture and mixing them, forming the products by casting the resulting aerated concrete mixture into a mold and curing, characterized in that as a filler they use ash and slag waste from thermal power plants, which without any additional processing are introduced into the mixer, while subsequent curing is carried out directly dstvenno in forms without lids, which gas concrete mixture before pouring is heated to thermal tables to a temperature 25 ^o C, and after filling is maintained at a temperature of 80-90 ^o C with a duration of warming at least 6 hours.  2. The method according to p. 1, characterized in that before pouring the aerated concrete mixture, a face layer is formed when forming the blocks "face down": a decorative protective layer is applied to the bottom of the mold and held for at least 15 minutes to pour the aerated concrete mixture.  3. The method according to p. 1, characterized in that before pouring the aerated concrete mixture, a face layer is formed when forming the blocks "face up": a decorative protective layer is applied directly to the aerated concrete mixture at least 1 hour after pouring into the molds.
