AbstractAbout AuthorsReferences
A study was made of a heat-insulating material based on foamed liquid glass obtained by processing using microwave technology, which implies swelling due to the transition of water from a liquid state to a vapor state under the influence of electromagnetic waves. Compositions with various liquid glass hardeners were studied in order to find a replacement for the common Na2SiF6, since, despite its curing ability, it is toxic. The main problem of a group of materials based on foamed liquid glass is studied – low water resistance. The analysis of the selected modifying additives was carried out in order to compare and identify the optimal option. The initial assessment of the water resistance of the obtained material was determined by the wetting angle method. As a result of the experiments, it was found that Portland cement is the optimal modifying additive for creating an environmentally friendly, fire-resistant, heat-insulating material; based on the identified characteristics, the scope of its possible application is indicated.
