Composite Binders Based on Dust of Electric Filters

This paper discusses and suggests ways to use desalinated waste dust of electric filters as an individual or complex binder. The aim is to identify the possibility of the use of dust of cement plant electric filters as a binder material; to select the ratio of Portland cement and dust of cement plant electric filters in the composite bundle to develop a new kind of binder; to study physical and mechanical properties of samples of the binder and determine the most promising compositions. The objectives of this work are: to study sampling of samples; to create a composite solution based on Portland cement, electric filter dust and various types of sand; to study the microstructure of the source material and to develop a composite binder with improved strength and hydration characteristics. In this paper, a comparative analysis of Portland cement PC500-D0-N and waste dust of cement plant electric filters was performed; their granulometry, chemical and mineralogical compositions, micro-structures and physical and mechanical characteristics were studied. As a result, the feasibility of using the enriched dust of electric filters as an independent binding material or in a composite bundle with Portland cement was proved, and a promising direction for creating a complex binder was identified.
