Physical-Mechanical Aspects of Preparing Thermal Insulation Materials on the Basis of Liquid (Water) Glass

Article Preview

Abstract:

In the Czech Republic, liquid glass is mainly used for painting areas with higher surface temperatures, such as bonding agent of heat-resistant concretes, which require higher chemical resistance; it is also used as additional damp proofing for buildings with damp brickwork. Globally, liquid glass is used with expanded perlite as thermal insulation for higher temperature (maximum application temperature of 650 °C). This paper should outline the possible preparation of such material in our conditions and verify, whether it is possible to achieve the bulk density for such material of up to 200 kg/m3, or the potential application of such material.
