Abstract

The scientific article relates to the building materials industry, namely, to the production of autoclaved cellular concrete. The purpose of the study was to reveal the potential possibilities of aerated concrete manufacturing technology. The following are considered as basic processing stages: preparation of the silica component, carried out by an energy-intensive and metal-intensive method - grinding in a ball mill; cutting of the raw mass with the formation of a crust - recyclable waste, the use of which only in the raw mixture does not allow obtaining the maximum technical and economic effect. It is shown that a fundamentally new method of using reverse sludge when grinding quartz sand makes it possible to manufacture a modified silica component. An assessment of its properties was given, which made it possible to reveal the mechanism: increase in sedimentation and aggregative stability; pH shift towards basicity; the presence of an amorphous surface on the particles; increasing the degree of dispersion and the acquisition of the active component in CaO. Changes in the chemical composition of the modified silica component compared to the base component were revealed. Morphological analysis showed the formation of components of the polymineral composition and primary neoplasms of the silicate system. The advantage of obtaining and using a modified silica component is not only in increasing the efficiency of the grinding section, saving binders, improving the parameters of the production process, the prospect of increasing the operational physical and mechanical characteristics of the finished product, but also in the absence of the need for significant changes in technological conversions of existing lines for the production of aerated concrete.
