Abstract

This paper deals with the performance of concrete specimens confined with different glass fabric reinforcement in organic binder consisting of resins. Three varieties of glass fabrics such as woven roving (WR), chopped strand mat (CSM), and textile reinforcement have been studied in the investigation. Experiments have been conducted on unconfined and confined concrete cylindrical specimens under compression. The effect of number of layers on confinement has been studied for specific cases. Specimens have been tested under displacement control. It is observed from the experiments that there is an increase in load carrying capacity as well as energy absorption capacity for specimens confined with different glass fabrics, and these materials can be used for retrofitting applications. It is observed that, in the case of specimens confined with textile reinforcement, failure is less abrupt compared to WR and CSM. The experimental findings will help the designer to choose the appropriate material towards confinement for practical applications.
