Abstract: Non-fired fly ash gravel was obtained on the basis of fly ash of thermal power plant no 5 of JSC "SIBEKO", 15 % of Portland cement and the hardening accelerator. The gravel of 5-20 mm fraction and 6 months' air-moist curing is 900 density grade, P300 strength grade, frost-resistance grade - F35. The compositions of cement concretes of strength class from B10 to B25 were established and their physical and mechanical properties were determined using obtained non-fired fly ash gravel. They belong to the lightweight concrete according to the density (1817-1857 kg/m3). The introduction of superplasticizer SP-1 reduces water demand of concrete mixture and increases strength of concrete on fly ash gravel. © 2019 Published under licence by IOP Publishing Ltd.
