The Influence of Microcrystalline and Nanofibrillated Cellulose in XSBR Polymers on the Mechanical Properties of Jute Textile-Reinforced Cementitious Composites

Abstract

This research aimed to improve the impregnation of XSBR (Carboxylate Styrene Butadiene Rubber) polymer on jute yarns, and hence the mechanical properties of a TRCC (Textile-Reinforced Cementitious Composite). Thus, an experimental investigation on the use of microcrystalline and nanofibrillated cellulose as additives to XSBR admixture was carried out. Four different solutions containing XSBR are presented, and each solution-fiber interaction and each treated fiber-matrix interaction were analysed. For those interaction analyses, the influence of XSBR impregnation was evaluated via SEM (Scanning Electron Microscopy) and TGA (Thermogravimetric Analysis), while the mechanical properties of the non-treated and treated jute fibers were evaluated via direct tensile test, and the bond between the treated and non-treated jute yarn and the cementitious matrix was evaluated via pull-out tests. Results showed a prominent enhancement not only to the mechanical behavior of the treated fibers, but to the TRCC's as well. Mathematics Subject Classification (2020) MSC code1 · MSC code2 · more
