The Effect of Binder Types of Strengthening Panel for Shear Strengthening Reinforced Concrete Beams

Abstract This paper presents the shear behavior, crack patterns, and failure modes of reinforced concrete beams strengthened with geopolymer Portland cement mortar panels. The specimens were prepared in form panels a size 300 mm x 700 mm, each consisting 4 pieces. specimen produced dimension 150 2300 static monotonic loading test was carried out. To ensure strength used is based on target, compressive out at age 28 days, 3 samples each. According to results beams, maximum load beam strengthed increased by 34.98% 29.54%, respectively, compared control beam. addition causes it’s behavior change, becoming more ductile. also has an impact patterns modes. CB experience failure, which indicated appearance diagonal cracks along area point loading, whereas panel flexural failure.
