CEMENT CONCRETE AND MANUFACTURING METHOD THEREOF
To provide cement concrete and a manufacturing method thereof, capable of reducing the amount of emission of CO2, and improving strength development property while including a food material.SOLUTION: Cement concrete of the present invention is obtained by hardening and carbonation-curing a cement composition including cement, a food material, an admixture, and γ-2CaO SiO2. The admixture comprises an admixture including at least one kind selected from a group consisting of a blast furnace slag and a fly ash. Moreover, a manufacturing method of the cement concrete of the present invention includes the steps of: preparing a cement slurry by kneading a cement composition including cement, a food material, an admixture, and γ-2CaO SiO2 with water; filling the cement slurry in a formwork; preparing a hydration hardened body by curing the cement slurry filled in the formwork, followed by removing the formwork; and carbonation-curing the hydration hardened body. The admixture includes at least one kind selected from a group consisting of a blast furnace slag and a fly ash.SELECTED DRAWING: None
【課題】ＣＯ２の排出量を低減し、食材を含みながらも強度発現性が向上したセメントコンクリート及びその製造方法を提供する。【解決手段】本発明のセメントコンクリートは、セメントと、食材と、混和材と、γ－２ＣａＯ・ＳｉＯ２とを含むセメント組成物を硬化及び炭酸化養生してなり、混和材が高炉スラグ及びフライアッシュからなる群から選択される少なくとも１種の混和材を含むものである。又、本発明のセメントコンクリートの製造方法は、セメント、食材、混和材、及びγ－２ＣａＯ・ＳｉＯ２を含むセメント組成物と水とを混練してセメントスラリーを作製する工程、セメントスラリーを型枠に充填する工程、型枠に充填したセメントスラリーを養生した後、型枠を取り外して水和硬化体を作製する工程、及び水和硬化体を炭酸化養生する工程を含み、混和材が高炉スラグ及びフライアッシュからなる群から選択される少なくとも１種の混和材を含む。【選択図】なし
