PURPOSE: A fast curing metal fiber-reinforced concrete composition is provided to maintain a long-term high strength and an excellent fast curing property while repairing a pavement, and to simply construct the pavement. CONSTITUTION: A fast curing metal fiber-reinforced concrete composition(12) contains 16~19wt% of ultra rapid hardening cement, 4~5wt% of linear steel fiber, 33~39wt% of small aggregate, 34~35wt% of thick aggregate, 6~7.9wt% of water, and 0.5~0.6wt% of water-reducing agent or a retarder. The length per diameter ratio of the linear steel fiber is in a range of 45~65. The maximum size of the thick aggregate is 20 millimeters. The slump value of the fast curing metal fiber-reinforced concrete composition is 4~5 centimeters.
