Recently, a unique Waste-based Particle Polymer Composite (WPPC) made from recycled foam glass and polypropylene has been developed at Brno University of Technology. WPPC was designed so as to provide both good thermal and mechanical properties in order to become a material of choice for thermally insulating construction details. However, before WPPC can be reliably used by construction designers, physical properties of WPPC must be accurately identified. Therefore, we studied thermal, mechanical, and moisture absorptivity of WPPC. In this work, we firstly present material structures of WPPC and difficulties related with experimental determination of WPPC´s physical properties. Secondly, we present measurements of coefficient of thermal conductivity using several experimental methods in order to show discrepancies among those methods. Thirdly, we show and discuss compressive properties of WPPC including Young´s modulus, strength and yield stress and their dependencies on testing temperature. Fourthly, we present measurement of moisture absorption. Finally, we compared experimentally identified physical parameters of WPPC with those of other common construction material in order to clearly show the application potential of WPPC. To sum up, we present an experimental study providing not only valuable data on physical properties of WPPC but also difficulties and discrepancies related to these experiments and we assess the potential of WPPC as a construction material. |
