The cement industry faces several major challenges today, including the need to reduce greenhouse gas emissions, the increased demand for sustainable construction materials, and the high energy consumption required for cement production. Cellulose nanocrystals have been studied as a potential additive for improving the properties of cementitious materials to help meet these challenges. Here are some examples:
Concrete: NanoCellX® can be added to concrete to improve its mechanical properties. CNCs can enhance the compressive and flexural strength of the concrete while reducing its brittleness. They can also improve the durability of the concrete by reducing its permeability to water and other liquids and improve its corrosion resistance. This allows the use of smaller amounts of concrete and reduce its overall carbon footprint.
1. Mortar: NanoCellX® can be added to mortar to improve its workability. They can also enhance the bond strength between the mortar and the substrate, resulting in a stronger and more durable bond.
2. Self-healing concrete: NanoCellX® can be used in self-healing concrete to improve its healing ability. They can enhance the formation of calcium carbonate crystals in the concrete, which can help seal small cracks and improve the overall durability of the concrete.
3. Cement composites: NanoCellX® can be used in cement composites to improve their mechanical properties and reduce their environmental impact. They can improve the strength and toughness of the cement composites while reducing their weight and carbon footprint.
4. Cement-based coatings: NanoCellX® can be used in cement-based coatings, such as those used for waterproofing or fire protection. They can improve the adhesion, flexibility, and durability of the coatings while reducing their environmental impact.
Overall, cellulose nanocrystals have the potential to improve the properties of cementitious materials in a wide range of applications, and research is ongoing to explore their full potential.
