A Study on Strength Characteristics of Confined Concrete Columns using Textile Reinforced Concrete

Based on the experimental investigation, the following conclusions are drawn: ●          The addition of TRC to RCC columns led to substantial increases in compressive strength ranging from 52.21% to 71.96% across curing ages of 7, 14, and 28 days, for both 150×150×500 mm and 200×200×500 mm column sizes. ●          The significant strength improvements achieved suggest that TRC confinement could enable the use of smaller column dimensions while maintaining required load-bearing capacity, leading to more efficient structural designs and potentially reduced material usage. ●          Consistent strength enhancements across two different column sizes demonstrate the versatility of the TRC reinforcement approach, indicating that its benefits can be leveraged across a wide range of structural applications. ●          The smaller TRC-C1 column (150×150×500 mm) outperformed the larger RCC-C2 column (200×200×500 mm) in compressive load capacity, confirming the potential benefits of TRC in terms of load-bearing capacity and overall strength. ●          TRC utilisation offers enhanced design flexibility; the observed dimensional efficiency with TRC suggests that this material can achieve desired structural properties while potentially reducing the overall weight of the structure. ●          The substantial increases in compressive load achieved with TRC reinforcement indicate that this technique can contribute to enhanced structural performance, including improved load-bearing capacity, ductility, and overall durability of RC columns.
