COMPOSITION FOR CONCRETE AND MOLDED PRODUCT FORMED BY MOLDING THE SAME
To provide: a composition for concrete having low carbon durability which expresses freeze-thaw resistance even in a small amount of cement; and a molded product formed by molding the composition.SOLUTION: A composition for concrete contains: a fine aggregate including a blast-furnace slag fine aggregate; a coarse aggregate; a binding material including cement; water; and an air-entraining agent. A unit cement content is 192 kg/m3. A mass ratio of water to the binding material is 25%. A mass ratio of the cement to the binding material is 30-40%. A mass ratio of the blast-furnace slag fine aggregate to the fine aggregate is 100%.SELECTED DRAWING: Figure 8
【課題】少ないセメント量でも凍結融解抵抗性を発揮する低炭素型耐久性のコンクリート用組成物およびそれを成形してなる成形品を提供する。【解決手段】高炉スラグ細骨材を含む細骨材と、粗骨材と、セメントを含む結合材と、水と、空気連行剤を含有するコンクリート用組成物であって、単位セメント量が１９２ｋｇ／ｍ３であり、前記結合材に対する水の質量比が２５％であり、前記結合材に対する前記セメントの質量比が３０～４０％であり、前記細骨材に対する前記高炉スラグ細骨材の質量比が１００％である。【選択図】図８
