The role of microfillers in shaping the sulphur concrete performance

The article presents the research results of sulphur concrete - the material that is created at high temperature as a mixture of a sulphur binder with aggregate and microfillers. While it has very interesting properties, it is not as appreciated as it should be. The aim of this paper is also to encourage a deeper insight into the presented material, and the use of its hidden potential. Sulphur concrete is not new a product of modern technology - it has been known for decades, but new applications are still being found. The paper focuses mostly on the impact of the microfillers used on some properties of the concrete. In the research, the microfillers used were: fly ash, microsilica and zeolite. The article presents the microfillers’ influence on the growing kinetics of compressive and flexural strength and the effects of abrasion on the sulphur concrete. The lab tests were carried out after 3, 7 and 28 days. The most noticeable was the positive influence of the fly ash on concrete performance. The microfillers that influenced the material’s microstructure were also presented.
