Aging of lime-based TRM composites under natural environmental conditions

Textile-reinforced mortar (TRM) composites, composed of textile fibers embedded in an inorganic matrix, have been found to be a sustainable solution for strengthening existing masonry and concrete structures. Despite the extensive recent attention understanding mechanical performance these composite, their long-term durability remain basically unknown. To address this gap, paper presents comprehensive experimental analytical study on changes response composites across scales (from material characterization bond tensile tests TRM composites) under indoor outdoor conditions. For purpose, steel glass with lime-based are used investigate pull-out behavior composites. The results show that different ages is significantly dependent fiber combination and, therefore, can change notably between solutions. It also observed TRMs cannot reach full properties conditions even after 3 years. Outdoor lead better curing samples achieving higher However, it significant deterioration at later ages.
