Abstract | Full Text

High Performance Fiber Reinforced Concrete (HPFRC) has been proposed to be used as a repair material for the deterioration of concrete structure since its very low porosity that leads to a low permeability and high durability. This characteristic makes it suitable for rehabilitation and retrofitting reinforced concrete structures or for as a new repair material. The bond strength between HPFRC and old concrete should have a good bond strength, thus surface preparation method and curing method can help strengthen the bond strength between HPFRC and normal concrete. This paper was performed to study the effect of surface preparation and curing method on the bond strength between HPFRC and normal concrete. In this study, three surface preparations were prepared: sandblasting, grooved and drill hole. Then, the curing methods that were performed in this study are ambient curing and water curing. The tests that were conducted to evaluate the bond strength between HPFRC and normal concrete are slant shear test and splitting tensile test. The result from this study shows that sandblasting gave the highest bond strength result between normal concrete and HPFRC. For the curing method, water curing gives the highest bond strength between normal concrete and HPFRC.
