SOLUTION : The cement composition includes portland cement, a limestone powder, an inorganic expanding material, a fine aggregate, a lightweight aggregate, and a re-emulsified resin powder, and the lightweight aggregate is obtained by firing a raw material containing glass as a main component. The re-emulsified resin powder contains a styrene-acrylic copolymer resin as a main component and has a glass transition temperature (Tg) of -10 to 22°C.
