Study of mineral components influence on foam system properties

[摘要] In the article, the properties of foams obtained by activating an aqueous solution of a synthetic foaming agent, produced in Russia, are considered. According to the results, the foaming agent has sufficient characteristics that meet the requirements for building foaming agents. However, to improve the quality of materials, it is necessary to increase the foam stability. For this purpose it is proposed to use a mineral modifier of silicate composition (NM) based on quartz sand, obtained by wet stage milling of raw materials in a ball mill. The results of experimental studies show the effectiveness of NM introduction as a foam stabilizer. The use of a modifier during the foam system preparation leads to an increase in its stability in time and volume: the foam stability rises to 120 min, which is sufficient for the cement-based binding system with NM, offered for the further production of non-autoclaved cellular composites.
