Refractory foam concrete for nuclear power
https://doi.org/10.17073/1683-4518-2023-1-38-45
Abstract
The composition of refractory foam concrete for long-term use at high temperatures in the nuclear power industry has been developed. Foam concrete based on Portland cement has an average density class of D700 and a maximum permissible application temperature class of I5 (500 °C). It is shown that Refractory foam concrete has improved deformation characteristics in terms of axial tension and flexural tensile strength. Changes in the strength of refractory foam concrete with an increase in the heating temperature of samples up to 400 °C, as well as its strength during prolonged exposure (up to 2000 h) at 200 and 400 °C. are presented. A thermodynamic calculation is given with the possible formation of low-base hydrosilicates (gyrolite and afwellite) up to 400 °C, which is confirmed by the results of studies of the phase composition of samples of refractory foam concrete. Ill. 8. Ref. 23. Tab. 5.
