PROBLEM TO BE SOLVED: To provide a curable composition and a section restoring material with improved practical applicability by preventing sagging and drawbacks in trowelability of the section restoring material. SOLUTION: The curable composition comprises (A) a polymerizable acrylic liquid composition containing an organic peroxide, (B) a curing initiator generating a free radical by decomposition of the organic peroxide and (C) short fibers with 0.5-20 mm length and 50μm or less diameter used for restoration of surface of concrete by mixing and spreading 100 pts.wt. (A)+(B) and 1-10 pts.wt. (C). The powder form section restoring material comprises (A), (C) and (D) a powder form aggregate composition composed of a curing initiator and silica sands, and used for coating the section restoring material prepared by mixing 100 pts.wt. (D), 40-100 pts.wt. (A) in the claim 1, and 0.3-5 pts.wt. (C). COPYRIGHT: (C)2004,JPO
