Thermally insulated cellular geopolymer

When creating a quality cellular concrete, the method of forming a porous structure is to introduce thermal vacuum and thermal vibration vacuum into the production process. It is also necessary to control the balance of porosity in the prepared cellular concrete mixture, which determines the properties of the final product. The impact of vacuum and temperature at the initial stage of the production of cellular geopolymer concrete significantly affects the formation of a high-quality porous structure. The authors presented graphical models of changes in the phase composition for thermal vacuum cellular geopolymer concretes with the use of an air-entraining additive and a foaming agent. A method for the manufacture of aerated concrete products has been developed, based on thermal vibration vacuumization of a concrete mixture, a feature of which is a fixed temperature of mixing water, shape and the mixture. This method makes it possible to increase the compressive strength of cellular concrete by 35-40% while reducing the average density by 1.5-2 fold. The solution to the issues of efficient production and use of cellular concrete is possible on highly porous materials with specified characteristics, obtained using composite binders, developed taking into account the phenomenological model of the formation of the volumetric phase composition of dispersed systems and prescription-technological factors for the design and synthesis of a highly organized structure, the use of which will ensure the construction of energy-efficient structures with given technical and economic indicators.
