Recycling sawmilling wood chips, biomass combustion residues, and tyre fibres into cement-bonded composites: Properties of composites and life cycle analysis

This study investigated the properties and sustainability of cement-bonded composites containing industrial residues such as wood chips, tyre fibres biomass combustion residues, i.e. bottom ash (BA) fly (FA). The effect cement-to-raw material (wood/tyre fibre) ratio (C/RM) aggregate content (BA FA) on thermal mechanical were investigated. Scanning electron microscopy (SEM) life cycle analysis (LCA) also conducted. results revealed that increased in composites, increased. mean conductivity volumetric heat capacity composite samples 0.37 W/mK 1.2 MJ/m3K respectively, while respective values for 0.29 0.81 MJ/m3K. SEM showed adequate bonding between wood/tyre cement matrix. LCA materials share total primary energy use was about 60% all analysed composites.
