Lightweight Concrete Manufacturing Technology Based on Waste Energy Raw Materials Alkaline-Activated

This article focuses on the compression strength of lightweight concrete based on alkaline-activated waste materials. The problem is important not only because of the possibility of disposal of excessive amount of building or industrial waste, but also because of the decreasing amount of natural aggregate deposits. Apart from the problem of the decreasing amount of natural aggregate deposits, there is also a problem related to the emission of greenhouse gases from cement production processes. It is estimated that the synthesis of alkaline-activated composites is twice as energy-intensive as the production of Portland cement and generates 4-8 times less carbon dioxide. Alkaline-activated concrete production can therefore lead to a significant reduction in environmental impact. The paper presents a thesis that there is a possibility of a monolithic combination of an alkaline activated mineral binder with an artificial ash-porbit aggregate, which will contribute to the improvement of the compression strength of light concrete based on alkaline activated energy waste materials and elimination of Portland cements.
