The article shows the use of TPP fly ash in the production of non-autoclaved cellular concrete. Of the two types of cellular concrete - aerated concrete and foam concrete, more than 90% of the total volume in the late 80s of the last century was predominantly made up of the production of aerated concrete. This was due to the fact that when using foaming agents - active retarders of setting and hardening of cement, to gain plastic strength of the concrete massif, necessary for the start of heat and moisture treatment (HMT), the holding time increased from 4–8 to 8–24 h, which led to an increase in the cyclicity and metal intensity of their production. The article presents the initial raw materials for the production of non-autoclaved foam concrete, showing compositions with a density grade from D600 to D400. Strength indicators of foam concrete under compression for 28, 56 days and after heat and moisture treatment are determined. Their shrinkage deformations are presented, and the factors influencing shrinkage during drying are indicated.
