Fiber Concrete on the Basis of Composite Binder and Technogenic Raw Materials
In the article the questions of application of the mining waste: dropout of quartzite sandstone crushing as filler in the fibre concrete production were considered. Composite binders based on cement and dropout of quartzite sandstone crushing were also developed. The effectiveness of composite binders’ usage consisting in improving the physical and mechanical characteristics and reduction of their prime cost compared to the cement with a slight increase in the complexity of their production was proved. The compositions of concrete dispersed reinforced with steel wave fiber and without it were developed. The efficiency of the use of dispersed reinforcement of fine-grained concrete is proved, which consists in improving the performance characteristics.
