CEMENT COMPOSITE MATERIAL
To provide a cement composite material having rapid-hardening properties, durability, and reduced in static elasticity modulus.SOLUTION: A cement composite material comprises a cement, a rapid-hardening cement admixture, a polymer for the cement admixture, a setting retarder, and an aggregate, in which: the aggregate comprises a light-weight aggregate having absolute dry density of 1.0-2.3 g/cmand a heavy-weight aggregate having an absolute dry density of 3.5-8.0 g/cm; and the polymer (solid content) for the cement admixture is 4-14 pts.mass based on 100 pts.mass of a total mass of the cement and the rapid-hardening cement admixture.SELECTED DRAWING: None
【課題】速硬性と耐久性を有し、静弾性係数を低減させたセメント複合材を提供する。【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、凝結遅延剤及び骨材を含み、前記骨材が、絶乾密度が１．０〜２．３ｇ／ｃｍ３の軽量骨材及び３．５〜８．０ｇ／ｃｍ３の重量骨材を含み、かつ前記セメント混和用ポリマー（固形分）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質量部であることを特徴とするセメント複合材。【選択図】なし
