| Summary: | This article discusses the effect of caustic soda on the intensity of gassing in the production of non-autoclaved aerated concrete. It has been found out that adding 0.8 and 1.0 percent of caustic soda increases the amount of released hydrogen by 20-40%. This is due to caustic soda increasing the alkalinity of the medium, which intensifies gassing. Exceeding the optimum amounts of caustic soda rapidly increases the elastic strength and worsens the ‘swelling’ of the AC mixture. Physico-mechanical tests of aerated concrete samples showed a considerable improvement in properties compared to the control composition. |
