Prospects for the use of foam glass in construction
G.V. Sopegin Perm National Research Polytechnic University, Perm, Russian Federation
Any construction cannot do without the use of heat-insulating materials, the main quality indicators are: thermal conductivity, average density and porosity. To ensure the necessary operational parameters heat-insulating materials must have high porosity, low average density and low values of the thermal conductivity coefficient. An important criterion is also theirs durability and environmental safety. However, few of the currently used heat-insulating materials meet the requirements of safety and durability. The most effective heat-insulating material from the point of view of operational, physical and mechanical properties is foam glass. It is obtained by foaming a glass-forming mass with different types of blowing agents. High porous structure and inorganic composition of foam glass to provide the high thermal properties and resistance to aggressive media. This article presents the comparative characteristic of modern heat-insulating materials. The main disadvantages of heat-insulating materials are revealed. It is shown that foam glass is the most effective heat-insulating material for Russian climatic conditions. Presents the main types and properties of foam glass, the field of its application.
