PROBLEM TO BE SOLVED: To obtain a self-leveling material in which Portland cement is a main component of a hydraulic component, the self-leveling material having excellent workability and hardening properties and, in particular, being capable of achieving stable fluidity even when the amount of unburned carbon in blast-furnace slag fluctuates.SOLUTION: A self-leveling material includes a hydraulic component, blast-furnace slag, fine aggregate, a plasticizer, and a setting modifier, wherein the hydraulic component comprises 20-50 mass% of Portland cement, 25-50 mass% of alumina cement, and 15-45 mass% of gypsum, the fine aggregate contains less than 5 mass% of a coarse-grained fraction having a grain size exceeding 600 μm within 100 mass% of fine aggregate, the amount of unburned carbon contained in the blast-furnace slag is less than 0.18 mass%, and the Blaine specific surface area of the blast-furnace slag is in a range of 2,500-6000 cm/g. |
