Concrete structures and elements are often exposed to different aggressive environment. It leads to failures, cracking, weathering and deterioration of concrete materials. Under aggressive conditions, the concrete is liable to a corrosive process which is not usually caused by one specific factor but by combination of aggressive media. Sulphur environment is one of the most corrosive factors influencing the concrete durability.
The paper presents the results of the comparative study of the resistance of the Slovak origin zeolite based cement composites and cement composites with addition of silica fume meeting the requirements of aggressive sulphur environment. The five aggressive media were used for concrete resistance study. The leaching of the calcium and silicon ions from concrete specimens, as well as the chemical composition of samples have been studied by using X – ray fluorescence method (XRF).
