Abstract

This work presents an experimental investigation focused on the mechanical properties of a Textile Reinforced Concrete fabricated with bi-directional sisal fabrics treated with three different procedures. The treatments consisted of immersion in a suspension of nano-silica, mechanical peeling and mechanical peeling followed by immersion in a suspension of nano-silica. Results indicated that the treatments on the fabric influenced the cracking process of the composites and were capable to improve their post-cracking tensile strength and the yarn-matrix bonding. The combination of nano-silica and peeling treatments proved to be more effective than the treatments applied independently.
