- Abstract
- The endurance research results of autoclaved gas concrete with fine-grinded additions of limestone, dolomite, marble and chalk under the action of carbonic acid of 100-percent concentration for 40 days aregiven. It is shown, that the concrete endurance with the additions indicated under the action of highly-concentrated CO2 rises considerably. This article also cites the results of research of phase composition and structural porosity of gas concrete in building fence constructions with the different terms of exploitation. The investigation of the phase composition of wall material extracted from different depths was made with the help of chemical, radiographic and differential thermal analyses. And the investigation of structural porosity was made with the help of mercury porometry and IR-spectroscopy methods.
