The paper presents studies on the use of ash of hydraulic removal in combination
with modifier additives in the production of non-autoclaved foam concrete. The research is
aimed at obtaining high-quality non-autoclaved foam concrete based on industrial waste with
high construction and technical properties. The main objective of the paper is to determine the
quality indicators of non-autoclaved foam concrete, according to standard methods,
corresponding to the normative and technical documentation. The studies were carried out
under laboratory conditions on certified and calibrated test equipment. The industrial waste
considered in the paper, the ash of hydraulic removal and food industry waste, are common
waste in all countries of the world, which gives high relevance to the research topic within the
framework of waste disposal. The conducted studies confirmed the effectiveness of the
integrated use of waste, to obtain the best result. As it is known, ash reduces the thermal
conductivity, which is a positive effect, but at the same time reduces the strength of the
material and frost resistance. In the paper it was proved that with the use of oil processing
waste, it is possible to obtain an increase in frost resistance due to volumetric
hydrophobization, as well as with the use of alcohol production waste, a significant increase in
strength is achieved, due to the plasticizing effect of the casein contained (polymer
components) in the composition of alcohol production waste. The obtained results of the study
on thermal conductivity, strength and frost resistance confirm the effectiveness of the use of
ash in combination with modified additives based on food industry waste CM-2 and CMA-P.
In conclusion, a comparative analysis of the effectiveness of the use of industry waste the ash
of hydraulic removal in combination with modified CM-2 and CMA-P additives is carried out.
