PROBLEM TO BE SOLVED: To provide a hydraulic composition which can be applied by troweling or spraying in the restoration of a cross section of a concrete structure, has a certain pot life in a wide temperature range of from a low temperature to a high temperature, and is excellent in trowel work efficiency. SOLUTION: The hydraulic composition contains cement, a fine aggregate, a fibrous mineral, a water reducer, an organic acid salt, an anti-skinning agent, an expansive material, and a resin powder. The hydraulic composition can be applied by troweling or spraying in the restoration of the cross section of the concrete structure in the civil engineering and construction field, has a certain pot life in a wide temperature range of from a low temperature to a high temperature, can be coated as a thick film, and is excellent in trowel work efficiency.
