Abstract
The paper presents the data of experimental studies on the development of compositions of porous gypsum materials using gas-forming substances and modifying micro-additives. The cold-resisting characteristics of samples differing in composition and density have been determined. The obtained characteristics correspond to the requirements of the standard for gypsum tongue-and-groove slabs intended for wall structures. Conclusions are made about the effectiveness and prospects of using gypsum-based cellular building materials for the manufacture of wall structures.
