Patch repair is a method that may be applied to recover damaged concrete. Mortar can be selected as the patching material. However, certain admixtures can be added to modify this material to increase its bond strength, tensile strength, and ductility. The addition of synthetic microfibres is expected to improve the repair material's tensile performance, including its resistance to crack formation, ductility, flexural strength, and tensile strength. This research determined a direct tensile strength of repair mortars on specimens with dimensions of 10x10x25 cm with triangular cobs in the middle of the specimens. The results show that adding synthetic microfiber can increase the value of tensile strength, toughness modulus, and linear elastic energy fracture in the repair mortars. It is also found that the synthetic microfiber with a content of 0.06% gives the maximum tensile performance. [ABSTRACT FROM AUTHOR] |
