A Reactive powder concrete is one of Ultra High Performance Concrete developed through microstructure repair. This research uses silica fume and steel fibre with w/c = 0.23. The curing temperature variations used in the study were 27°C, 60°C, 90°C, and 120°C. Testing methods slump flow, compressive strength, modulus of elasticity, tensile strength and flexural strength were performed based on ASTM and ACI. This research shows that the compressive strength, modulus of elasticity, tensile strength and flexural strength are directly proportional. The optimum temperature of the study was 90°C. The compressive strength and maximum modulus of elasticity this study were 111.43 MPa and 51,400 MPa at curing temperature of 90°C. Tensile strength and maximum flexural strength in this study were 6.19 MPa and 10.82 MPa at curing temperature of 90°C.
