The effect of hardening activators on the physical and mechanical properties of slag-alkaline binding materials

Abstract

The article presents the results of the study on preparation of rational compositions of slag-alkaline binders using blast furnace granulated slag from JSC "Zaporizhstal", which, according to their physical and mechanical properties, can be suggested as a basis and a surface layer for the production of high-strength wear-resistant paving slabs that will meet the requirements of Ukrainian state standards. The involvement of different groups of industrial waste in the production of paving slabs will allow expanding the raw material base of domestic enterprises, reducing the cost of production by 2–4 times without lowering its quality, and reducing the cost of primary raw materials by up to 80%. Thanks to these developments, waste-generating enterprises, as well as landfill keepers, will be able to reduce the volume of accumulated waste and costs associated with environmental protection measures, which will minimize the negative impact of accumulated waste on the environment and human health.
