Curing takes place immediately after concrete placing and finishing. Curing conditions affect on the concrete properties. One of those conditions is curing temperature. This research aims to study the effect of curing temperatures on the main mechanical properties of fibrous concrete compared to that of conventional concrete. Two types of fibers were used, polypropylene and steel fibers. The effect of temperature of curing (25°C, 50°C and 75°C) was considered. The study is performed depended on the results obtained from compressive test, indirect tensile and flexural test at 3, 7 and 28 days. The test results showed that, the increasing ratio of the tensile strength and the flexural strength was better than the increasing ratio of the compressive strength with using the fibers in concrete compared to the control concrete. The curing temperature affected on the compressive strength more than the effecting of the tensile strength and the flexural strength. The better used curing temperature is about 50°C.
