One of the effective ways to increase the durability of building products and structures operating under the influence of aggressive media is using sulfur binders to manufacture concretes. It is shown that the chemical resistance of sulfur concretes to a greater extent depends on the chemical resistance of the matrix composition. It was found that the introduction of modified additives increases their chemical resistance. With the optimal content of additives, the water resistance of the composites increases from 2.3 to 3.2 times in comparison with the composition without additives. The highest chemical resistance in alkaline media and solvents and oils is characteristic of compositions filled with pyrite cinders. Formulations filled with quartz powder showed increased chemical resistance in acid solutions.
