This article is devoted to the description of methods for improving the efficiency and production of autoclaved materials and lime, as well as an increase in safety in their production. The basis of the proposed technical and technological methods is a new method for the production of autoclaved materials. As part of the scientific work on improving the quality of autoclaved products, an additive (copper sulphate) was found, which makes it possible to slow down the lime hydration time in the binder for several hours, which makes it possible to apply the mechanical activation of lime-silica binder with wet grinding and improve working conditions in the workplace.
