Abstract. This article investigates the influence of industrial waste on the properties of concrete. The components used include microsilica (Ms), phosphogypsum (PhG), soapstock (Sp), post-alcohol distillers’ grains (PaB), and caustic soda (NaOH). The research aims to assess the impact of each of these components on the properties of concrete. Special attention is given to the influence of post-alcohol distillers’ grains on the transformative processes of concrete, specifically its strength indicators, water absorption, and frost resistance. A reference sample is presented as a cement-sand mixture with a 20% inclusion of microsilica, 15% phosphogypsum content, and 10% soapstock content by the weight of cement, microsilica, and phosphogypsum. As a result, hydrophobic concrete with increased strength is obtained. This research represents a significant step towards sustainable construction practices, utilizing industrial waste to enhance the properties of concrete.

Keywords: phosphogypsu, soapstock, concrete, additive, two-component modified additive, concrete strength.
