Zusammenfassung:	To provide a light-weight cement composite material having rapid-hardening properties and small dry-shrinkage strain.SOLUTION: A cement composite material comprises a cement, a rapid-hardening cement admixture, a polymer for cement admixture, a retarder, and a light-weight aggregate having dry density of 1.0-2.3 g/cm, wherein the polymer for cement admixture is 4-14 pts.mass based on 100 pts.mass of the total of the cement and the rapid-hardening cement admixture. Preferably, the light-weight aggregate is a coarse aggregate having absolute dry density of 1.0-2.0 g/cm.SELECTED DRAWING: None 【課題】速硬性を有し、乾燥収縮ひずみが少ない軽量のセメント複合材の提供。【解決手段】セメント、速硬性セメント混和材、セメント混和用ポリマー、凝結遅延剤及び絶乾密度が１．０〜２．３ｇ／ｃｍ３の軽量骨材を含有し、かつ前記セメント混和用ポリマーが、セメントと速硬性セメント混和材の合量１００質量部に対して４〜１４質量部であるセメント複合材。更に、軽量骨材が絶乾密度１．０〜２．０ｇ/ｃｍ３の粗骨材であることが好ましい。【選択図】なし
