Abstract

Textile fine grained mortar (TFGM) is a composite construction material which provides another alternative to strengthen and repair existing concrete structures. TFGM is a combination of fine grained mortar (FGM) made of waste material with textile fabrics. The strengthening approach significantly increases both the ultimate load carrying capacity and the serviceability. FGM is a special binder matrix with maximum grain size of 600–1 mm. Therefore, less than 2 mm mortar thickness is needed between the textile layers due to the small aggregate size. In addition, 10 % of cement content in FGM is replaced by palm oil fuel ash (POFA) as a waste material. The utilization POFA can reduce the carbon dioxide emission generated by cement, which can be harmful to the environment In this study, plain concrete prism with size of 100 mm × 100 mm × 500 mm was produced. Specimens were strengthened by using alkali resistant (AR) glass fabrics impregnated with FGM. Four levels of strengthening consisting of 2, 4, 6 and 8 layers fabric were used on three replicate specimens in each category. Strengthened concrete prisms were subjected to monotonic load with three-point bending test to determine the effect of the strengthening process and the number of fabric layers on the behaviour of concrete prism. The recorded measurements on the test specimens were evaluated for the ultimate flexural strength and deflection. TFGM significantly contributed on the flexural load carrying capacity and ductility of concrete prisms. The contribution of these composites varies according to the number of fabric layers. The flexural capacity increased about threefold from unstrengthened plain concrete prism.
