Lithology of turtass suite rocks and opportunities of their use as a raw material for foamflass ceramics on the example of Uspenskaya area (Tyumen region)
Abstract
Relevance of the discussed issue is caused by the necessity to expand the local mineral resource base of Tyumen region for producing a large range of modern building and insulating foamglass ceramics materials. The main aim of the research is to study the chemical and mineral composition of sediments of Turtass suite of Upper Oligocene to determine the possibility of their use as a raw material for producing building and insulating foamglass ceramics materials on the example of Uspenskaya area (Tyumen region). The methods used in study: field investigations, reconnaissance of the area, macroscopic study, X-ray fluorescence analysis, X-ray analysis, petrographic analysis, electron microscopy, diatom analysis, technological tests in accordance with the RF patent № 2464251 and TC 5764-001-90903792-2013. The results. The carried out investigations show that the significant content of frustules of diatoms and their fragments (10 %), formed by X-ray amorphous opal, combined with mixed layers of formation (corensite, tosudite etc.), which form the clay part, actively engages with weak alkalis and, consequently, define the opportunities for their wide use in production of foamglass ceramics materials. During the pilot testing the authors have obtained the samples of foamglass ceramics materials, which meet the RF patent no. 2464251 and TC 5764-001-90903792-2013 in part of bulk density, compressive strength, water absorption by volume, softening coefficient and thermal conductivity. Multifunctionality of the material allows planning the production of a wide range of products in demand in industrial, civil and low-rise wireframe, road construction, oil and gas industry, landscape design: building blocks, dry construction mixtures, fillers in concrete, foamglass ceramics blocks, bulk insulation for roads and grounds.
