Abstract
This research involves the preliminary study of utilizing fly ash-based geopolymer mortar in the textile reinforced mortar (TRM) system for concrete strengthening. Results showed that adequate compressive strength of geopolymer mortar with respect to normal cement mortar could be produced. Geopolymer mortar without styrene butadiene rubber (SBR) had higher compressive strength and exhibited superior efficiency in the TRM-flexural strengthening of concrete prisms compared to the geopolymer with SBR as well as the corresponding cement-based mortars. Findings from this study suggests good potential of geopolymer to be further developed in TRM for strengthening applications.
