Abstract
Cellular glass by its composition, structure and technical parameters is a high-performance multifunctional material, and its use in construction and engineering is extremely important. The problem of developing cellular glass power consumption technology on the base of natural amorphous aluminosilicates and silica rocks in a single technological process, combining the synthesis of a given glass composition and the formation of its cellular structure is solved by introduction of a nanodispersed modifier into the rock and by the mechanical activation of the charge, creating an impact possibility in the system at the atomic-molecular level. With the involvement of a complex modern theoretical and experimental methods, the processes of glass wool rock modifyed sintering and expanding were investigated, which served as a base for creating the cellular glass technology in the form of products and granules. The study of the secondary glass synthesis dynamics during sintering of volcanic glasses with sodium hydroxide solution showed that the hydrated amorphous neoplasms of sodium silicates synthesized at low temperatures and silica aluminosilicates with temperature rise gradually enriched with silica and formed hydrated secondary glasses, the dehydration of which expanded the mass upon reaching the pyroplastic state. Power consumption technologies of the new type cellular glasses based on the volcanic glass-wool and other amorphous silicate rocks, which allow to combine the processes of synthesis of low-melting glass and its expansion by sintering are challenging for the production and for application in construction and engineering.
Highlights
Modern methods of industrial construction of residential and industrial facilities require a significant improvement in the quality of building materials, providing reliable thermal protection, efficiency, environmental cleanliness, seismic resistance, comfort, etc
As a thermal insulation material, it is used in all areas of construction, in high and low temperature techniques, in the chemical industry and energetics, as a decorative and acoustic material, aggregates for artificial conglomerates, in shipbuilding and communications, etc
Due to the interaction of amorphous silicate and aluminosilicate rocks with sodium hydroxide solution, hydrated newly formed particles of silicates are formed, which are made of monomeric sodium cations and nanoscale polymeric silicon-oxygen anions
Summary
Modern methods of industrial construction of residential and industrial facilities require a significant improvement in the quality of building materials, providing reliable thermal protection, efficiency, environmental cleanliness, seismic resistance, comfort, etc. This can be achieved with the implementation of the production technology of the cellular glass based on volcanogenic glassy rocks of silicate and aluminosilicate composition (perlite, pumice, tuff, etc.) and Armenia is rich in this materials. As a result of maximum use of this raw material potential of specific natural properties, it is possible to obtain valuable and relevant products of relatively low manufacturing cost. Enterprises in Japan and China are successfully operating, there are enterprises in Belarus and Ukraine as well
