Joint Application of Stone Dust and Construction Demolition Waste in the Construction Industry

Abstract

In the Czech Republic, natural stone reserves at mining sites are decreasing. Mining companies face the problem of handling waste materials, especially when processing stone. The article describes research that proposes using stone dust in producing ecological building materials, the transition from a linear economy model to a circular one, and an investigation into the use of construction and demolition waste and basalt fibres. The results show that using stone dust in construction products, in terms of the consumption of binders and water, and its use through larger particles or manufactured aggregates, reducing the risk of deformations, is more effective work.
