aerated concrete

Waste (tailings) of mining and processing plants of Kryvbas were studied by the stages of their magnetic enrichment. The granulometric compositions of the tailings, the amount of iron (total and magnetic) and the mass fraction of solid in them are determined. The expediency of disposing of ferruginous quartzite waste at the first stage of enrichment as a silica component in cellular concretes is proved. Optimal compositions of aerated concrete mixtures are determined based on the following criteria: the average density of cellular concrete in the dry state and its compressive strength.

It is shown that solving the problem of energy saving of housing and public objects use is possible due to the growth of production and use of aerated concrete as an effective insulation material, which ensures the implementation of the concept of sustainable development of Ukraine. Analysis of the data of the Ukrainian Autoclaved Aerated Concrete Producers Association has shown that the demand for aerated concrete constantly increases, and the growth of its production is about 40–45 %.

There is investigated the effect of carbonate-containing and sulfate salt processing wastes on the properties of cementitious systems and aerated concretes based on them.
