The results of studies evaluating the possibility of increasing the water resistance of pressed magnesia composites for the purpose of their use in the construction of agro-industrial objects are presented. As a modifying filler, a secondary resource was used: the burnt rock from the mines of the Rostov region, which has pozzolanic properties. In the studied compositions, a modifying filler was replaced with 10 to 25% of the magnesian binder. The water resistance of the pressed modified magnesia composites was assessed by changing the values of the softening coefficients and water resistance of the control samples after they were kept in water for 1, 7, 28, 60, and 90 days. It is shown that the modification of the magnesia binder with burnt rock and compaction of molding mixtures by pressing makes it possible to obtain strong and durable composites that retain their physical and mechanical characteristics for a long time in wet conditions. The compositions of modified magnesia composites designed for the manufacture of small-piece pressed products for the walls and floors of low-rise residential buildings, as well as other construction projects of the agro-industrial complex, with indoor air humidity of more than 60%, have been developed. The use of a significant amount of waste from the coal industry as part of the forming mixtures should free up land allocated for dumps and contribute to improving the environmental situation in rural settlements. This allows attribyting the proposed method of manufacturing construction products to the best available technologies.
