Abstract
- Pulp fibre reinforced cement (fibre cement) has the potential to become a forerunner in mitigating the carbon dioxide (CO2) footprint of non-structural materials for residential and commercial structures. However, one of the significant bottlenecks in fibre cement is its poor chemical stability in the alkaline cement matrix. To date, probing the health of pulp fibre in cement is lengthy and laborious, requiring mechanical and chemical separations. In this study, we have demonstrated that it is possible to understand the chemical interactions at the fibre-cement interfaces by tracking lignin in a solid state without using any additional chemicals. For the first time, multidimensional fluorometry is employed for the rapid assessment of the structural change (degradation) of lignin in fibre cement as an indicator of pulp fibre health; providing an excellent platform for the germination of resilient fibre cement with high content of natural lignocellulosic fibre.<br /> (© 2023.
