Effect of carboxylated cellulose nanocrystals on the properties of cement and concrete composites

This project proposes the use of carboxylated cellulose nanocrystals (CNC) – developed and manufactured by Anomera Inc. from Canadian forest – as nano-inclusions to tailor a set of properties in cement and concrete composites towards enhanced performance. Due to its unique properties, CNC can significantly enhance the mechanical performance of cement and concrete composites. The effect of various doses of CNC on the cement hydration, as well as on mechanical properties (e.g., compressive strength, tensile resistance, and flexural capacity) and durability of cement pastes, mortars and concrete will be evaluated in this research. Project results are expected to promote the use of Anomera’s CNC material in construction industry, as well as to promote Canadian forest sector as Canada is considered among the global leaders in the exportation of forest products. Likewise, results will contribute to promoting the development of ecological materials for sustainable construction materials.
