Nano-cellulose filaments for sustainable high performance concrete matrix

克鲁格目前正在其位于Qc的trois - rivi<e:1>工厂生产纳米纤维素细丝（CF）。一般来说，与传统的聚丙烯或聚酯纤维相比，这种材料具有极高的抗拉强度。它们是亲水的，并且具有很高的长径比（纵横比），使它们在插入复合材料基体时有效地稳定裂缝。将CF掺入混凝土基体中，可以在力学性能和耐久性性能之间提供良好的平衡，并实现可持续发展。该项目的总体目标是开发使用CF结构的纳米纤维增强混凝土（FRC），其机械性能和耐久性可与混凝土合成纤维（钢，聚丙烯或玻璃）相媲美，而且成本更低，减少环境足迹和对加拿大的经济重要性。在本项目中，将研究Kruger生产的CF在FRC中的潜在应用。

Kruger is presently producing nano-cellulose filaments (CF) in its Trois-Rivières mill, Qc. In general, this type of material has extremely high tensile strength compared to traditional fibers made of polypropylene or polyester. They are hydrophilic and have also high length-to-diameter ratio (aspect ratio), making them efficient in stabilizing cracks when inserted in a composite material matrix. The incorporation of CF into a concrete matrix can potentially provide a good balance between the mechanical and the durability properties, and sustainable development.The overall objective of this program is to develop nano fiber-reinforced concrete (FRC) structured using CF with mechanical performance and durability comparable to those offered by concrete synthetic fibers (steel, polypropylene or glass) with, moreover, a lower cost, reduced environmental footprint and economic importance to Canada. In the present project, CF produced by Kruger will be investigated for potential application in FRC.
