Abstract
A homogeneous glass-mica composite solid with different physical structures has been developed from mixtures of natural mica powders of the phlogopite-type and ground glass powders prepared from recycled waste soda- lime-silica glass. The mixtures can be fabricated into com posite solid with a cellular structure which consists of both closed and open cells or into composite solid with a highly densified ceramic body which contains very low porosity. The two different structural solids can also be jointly fabricated together in the form of sandwich and multi-layer products providing both load-bearing and thermal insulation in a single unit. The glass-mica composite solids exhibit several basic qualities as a thermal insulator including insulation efficiency, safety, strength and durability. Laboratory test results show that these glass-mica composite solids have great potential as structural thermal insulating material for building construc tion and other applications because of their contribution to energy conservation. This paper discusses some of the material characteristics.
