What is it about?
The main focus of this paper was to improve the long-term performance of fabricated eco-cement composites and demonstrate the value-added use of carbon dioxide (CO2) in manufacturing sustainable products with better dimensional stability and moisture resistivity.

Why is it important?
The findings show that cellulose fibre growth in the transverse direction due to moisture conditions was observed to be efficient in strengthening the transition bonding areas with the matrix. In comparison to board length, the change in thickness and mass due to moisture effects was remarkable. This behaviour confirms that the composite final volume stability response is dominated by the orthotropic property due to the various constituents.
Perspectives
This manuscript builds on my prior studies, when I was a co-author, to improve environmental performance of the fabricated cementitious composites. The results of this study should help design team and site engineers, contractors and clients to choose appropriate manufacturing process of cementitious boards with enhanced final performance and better environmental impacts. The utilization of carbon dioxide in the present application reduces the greenhouse emissions and also avails the productivity of the cementitious board production plants.
