CARBONATION CURING METHOD FOR PRECAST CONCRETE MEMBER
To provide a carbonation curing method for concrete members that can be performed even at a factory or a construction site and enables CO2 to be efficiently immobilized using a simple facility.SOLUTION: In a carbonation curing method for cement hardened bodies, the cement hardened bodies are covered with an airtight curing sheet 2, and a gas including carbon dioxide is blown into the curing sheet 2 to produce calcium carbonate in the cement hardened bodies 1, immobilizing carbon dioxide. The curing sheet 2 is a heat-retentive sheet 2' with insulation capabilities. The heat of hydration of the cement hardened bodies 1 is used to promote the calcium carbonate producing reaction.SELECTED DRAWING: Figure 1
【課題】工場や建設現場でも実行可能な簡易な施設で効率的にＣＯ２を固定化させることができるコンクリート部材の炭酸化養生方法を提供する。【解決手段】セメント硬化体の炭酸化養生方法において、気密性を有する養生シート２でセメント硬化体を覆い、養生シート２内に二酸化炭素を含むガスを吹き込んでセメント硬化体１中に炭酸カルシウムを生成して二酸化炭素を固定化する。また、養生シート２は断熱性を有する保温シート２’であり、セメント硬化体１の水和熱で炭酸カルシウムを生成する反応を促進する。【選択図】図１
