Advancing sustainable infrastructure: Leveraging forestry waste fibers to enhance crack resistance and durability in repair mortar
Year: 2024
Type: article
Abstract: To reduce energy consumption in construction, minimize forestry waste, promote a circular economy, and resolve the issues of poor adhesion and cracking in repair mortar , this study uses waste wood fibers from phloem (WFP) as a reinforcing material. Additionally, vinyl acetate ethylene copolymer (VAE) copolymer is incorporated to enhance the toughness and durability of the repair mortar. The findings reveal that the inclusion of WFP-VAE significantly improves the workability of the repair mortar, reduces internal cracking, and enhances both tenacity and frost resistance . Moreover, the addition of WFP-VAE facilitates the formation of hydration products , thereby strengthening the interface between WFP and the cement matrix . Furthermore, WFP demonstrates superior thermal stability compared to conventional polyethylene fibers , while effectively mitigating the drying shrinkage behavior of the mortar. Notably, waste WFP contributes to a reduction in CO 2 emissions by up to 19.8 %, underscoring its role in advancing sustainable infrastructure and environmentally friendly production practices. In conclusion, the development of crack-resistant, wood fiber-reinforced repair mortar holds significant potential for improving the structural integrity of repair materials and promoting the efficient utilization of forestry waste.
