Ceria powder has extensive application in ceramic, catalyst, and solid electrolyte materials [5,6].
The chemical compositions of raw materials and products were determined by X-ray Fluorescence (XRF, Shimadzu, XRF-1800).
The first weight loss occurred between 120 ºC and 210 ºC, which was mainly due to the loss of absorbed and bound water of the raw materials.

Both thermoplastic polymers and elastomers were used as matrix materials with combination of fillers made from different materials having different aspect ratio and revealing a wide variation of alignments and arrangements.
The theoretical, material science and computational aspects of these methods are summarized in numerous publications and books [4-6].
PTFE, PA, PEEK) based compounds and composites, particle filled elastomeric materials were also modeled.

Thus, it can be possible to assess environmental impacts of building materials by using local data.
Identification of the Expert Panelists Panelists are selected from the environmental experts in the universities, government and building materials sector.
WFs are also evaluated separately according to the experts from the academia, government and building materials sector [Table 3].
