Assessment of the Prospects for using Self-Rescuer Waste as an Alkaline Component of Concrete Mixtures
Abstract: The article examines an important aspect of the environmental problem of accumulation of industrial waste in the coal mining industry: mine self-rescuers on chemically bound oxygen, which pose a danger to humans and the environment. These wastes containing valuable components can be reused instead of being disposed of (destroyed). The qualitative indicators of the chemical composition of the waste of self-rescuers with an expired shelf life are analyzed. The possible prospects for the secondary use of waste as an alkaline component for concrete mixtures are assessed. The alkalinity and pH levels of degraded waste after its slaking with water were experimentally studied depending on the density of the solution, which is necessary for further studies of cement-water suspensions with alkaline components from these wastes.
Keywords: environmental safety, waste recycling, self-rescuers on chemically bound oxygen, recycling of regenerative product, alkaline concrete.
