Composition of aerated concrete using local raw materials

This article presents the mechanical and physico-chemical properties of iron-smelting slag and technogenic sand.The issues of designing the thermal properties of structural heat-insulating aerated concrete blocks are considered, taking into account natural and climatic conditions, and the chemical reaction of iron smelting slag and waste sand and gas evolution reactions are presented.Study of changes in the properties of aerated concrete with the addition of waste quartz sand and steel smelting slag; optimization of aerated concrete composition by mathematical regression method and determination of physical and mechanical properties; the results of the research on automating the calculation of the proposed composition of aerated concrete and the amount of industrial waste according to its brand are given.
