Approach on Improving the Performance of Thermal Insulating and Acoustic Glass Composites

Abstract

This paper presents an approach on creating new high performance thermal insulating and acoustic glass aerated concrete composites. It consists in design of artificial building conglomerates on nano-, micro- and macro levels with correspondence of natural rocks. Heat-insulating glass composites have low thermal conductivity, high durability, ecological safety and durability, simplicity of installation. The obtained heat-insulating glass composite has compressive strength from 6 up to 8 MPa due to its cellular structure and glass properties. In addition, the material has easy abrasive treatment that allows to create products of any shape. The developed aerated concrete blocks have 42% less thermal conductivity with thickness of the block of 200 mm to ensure the necessary resistance of heat transfer. Adhesive shear strength of the mortar is in the range of 2.35 MPa. It is stated the decrease of the bond strength with the base of heat-insulating structural glass composite is less than 10.6% during the test of frost resistance, which does not exceed the standard value.
