Abstract: The paper describes the development of composite binders with low water demand, obtained by intergrinding Portland cement, Muroplast hyperplasticizer, and tailings of magnetic separation of jaspilites from the Kursk Magnetic Anomaly. The obtained composite binders possess high strength properties after steam curing. The modifying effect of tailings of wet magnetic separation of jaspilites proved to be highly efficient. Composite optimum content binders (with strictly fixed amount of modifier and its specific surface area) were used to obtain outofautoclave curing foam concrete with physical and mechanical properties that allow one to recommend the obtained product as a structural thermal insulation material. Scanning electron microscopy was used to study the foam concrete's pore structure and the distribution of pores and interpore walls across the volume of the material.
