Cracks should be repairs as soon as possible to prevent it from high risk such as structure collapse. In sequence to find the most excellent material to repair the structure, Unsaturated Polyester Resin (UPR) has been used as an alternative. In this study, it was focused on engineering and mechanical properties comprises of compressive and flexural strength. The compressive strength was tested to resin mortar cube and cement mortar cement as control sample with dimension of 70.5 mm x 70.5 mm x 70.5 mm. To produce cement mortar cube, there are three types of water to cement ratio (w/c) namely 0.45, 0.50, and 0.55 were considered. Otherwise, 12 specimens were prepared for the resin mortar cube with different percentages of resin comprises of 15 %, 20 % and 25 % by weight of sand. It was designed to obtain the optimum compressive strength of the cement mortar and resin mortar. Two types of curing condition namely water curing and air curing were considered at 1, 3, 7 and 28 days subjected to cement mortar and resin mortar respectively. The result revealed that, the optimum compressive strength was achieved for resin mortar made of 25 % resin is cured in 28 days. While, cement mortar designed using water to cement ratio (w/c) of 0.45 attained the highest result compared to those cement mortar. It noted that, resin mortar display highest in compressive strength compare to cement mortar. The flexural strength were tested to the prism composite and prism concrete with size of 100 mm x 100 mm x 500 mm. The result was recorded that the flexural strength of prism composite is higher than those prism concrete. It was showed that, resin is can be apply as an alternative material for strengthening and repairing of structure. -Author specialized Tengku Mazrul Amin B.
