Basic research on multilayer composites based on fly ash and natural fibers

Abstract

New restrictions on carbon dioxide emissions and electricity consumption are currently being introduced around the world. In many countries, innovative solutions are being used to reduce CO2 emissions and reduce material and energy consumption. The present work is related to the study of innovative binders based on geopolymers reinforced with composite bars and containing natural fibers for the production of layered building envelopes. The paper will present preliminary results of research on composites based on fly ash and natural materials of plant origin. The natural materials used to produce the samples are completely biodegradable. A 10-mol solution of sodium hydroxide with an aqueous solution of sodium silicate was used for the alkaline activation of geopolymers. The publication presents the results of physicochemical tests of base materials and natural materials, studies of thermal properties of fibers, mats, felts, and wools, morphology of fiber structure and texture, as well as physical and thermal properties of finished multilayer partitions. The results indicate the great potential of these materials in prefabrication and structural insulation applications. The work may have future applications in energy-efficient and low-carbon construction.
