简介
Landfill disposal of contaminated wood formwork from construction sites presents significant environmental burdens and economic wastage. This study proposed an innovative and low-carbon technology by using magnesia cement and CO2 curing to transform contaminated wood waste into eco-friendly cement-bonded particleboards, which demonstrated excellent compatibility and value-added properties. The microstructure characteristics and cement hydration chemistry were revealed by mercury intrusion porosimetry and X-ray diffraction analyses. At the optimal water to cement ratio of 0.3, the particleboards contained the lowest total pore area (10.2 m2 g−1) and porosity (26.1%), thereby successfully complying with the International Standards of mechanical strength (>9 MPa) and dimensional stability (<2% swelling after 24-h water immersion). An integration of 2-h CO2 curing facilitated carbonation at early …
