Development of composite binders based on volcanic tuff waste

Development of composite binders based on volcanic tuff waste

Large-scale wastes have accumulated from local volcanic tuff extraction in the Republic of Armenia. Like their natural rock material, they have a great range of colors and high chemical activity. This waste completely occupies precious space in an already scared space of republic. As a result, soil degradation and groundwater supply disruption occur, both of which are severe environmental problems. When humans or animals inhale the smallest particles in the air, apart from economic and ecologic issues, it causes health problems. The study aims to produce sodium-silicate composite binders that will enable large-scale accumulated waste to be used in making non-cement, artificial stone materials for tiles, architectural elements of buildings, and other stone items. The research carried out allows us to solve environmental problems such as the utilization of waste rock, degradation of agricultural land, economical use of natural resources (the extraction of mountain rocks), and the production of ecologically clean composites.
