Abstract
The present study evaluated the physical, mechanical and thermal properties of the foam glass aggregate and insulation foundation with this, in order to promote the use of insulated foundations using domestically produced foamed glass aggregates. As a result of the evaluation, the compacted foam glass aggregate showed at the same level as overseas products in terms of unit volume mass, particle size and other characteristics, and a compressive strength of 40.6 N/cm2, which was superior to the existing organic insulation materials such as XPS. And the thermal conductivity of the foam glass aggregate was 0.84 W/mK, and the thermal transmittance of the specimen simulating the insulation foundation was 0.37 W/mK, so the thermal conductivity of the foam glass aggregate was estimated to be 0.80 W/mK. With these results, it was found that it is possible to use the insulation foundation with re-producted foam glass aggregate by crushing the waste from the process of producing foam glass products.
