The paper presents research on sulfur concrete designed with the following combustion products: fly ash, slag and phospho-gypsum. The purpose of this investigation was to evaluate characteristics of sulfur concrete, including its mechanical and durability properties. It was established that mechanical characteristics of sulfur concrete will correspond with those of cement concrete used in the production of small precast members used in civil engineering, hydraulic engineering, road constructions, structures exposed to aggressive environments especially chemical industry, petroleum industry, food industry and farming. The test results confirmed low water absorption, high resistance to wear abrasion, high freeze-thaw scaling resistance (surface weathering) in a salty environment and high compressive and tensile strength of individual compositions. However, the tests results did not confirm the freeze-thaw resistance of the sulfur concrete specimens due to low freeze-thaw resistance of sulfur binders. Further research is needed to increase the freeze-thaw attack resistance of the sulfur polymer to provide the proper resistance of the final sulfur concrete products.
