The object of this study is the fire resistance of aerated concrete structures and methods for its enhancement. The study and improvement of the properties of aerated concrete is an urgent task in the field of construction. The purpose of the study was to find out what methods of improving aerated concrete exist. The authors reviewed the scientific and technical literature in the field of increasing the fire resistance limits for building structures made of aerated concrete. It is shown that there is no definition of aerated concrete in regulatory documents. Various methods for improving the fire resistance of aerated concrete have been investigated. Various characteristics of aerated concrete are considered. The conclusion is drawn about a wide range of advantages of aerated concrete. It is proved that the research of aerated concrete is promising in the modern world, there are many patents aimed at studying and improving the properties of aerated concrete
