MANUFACTURING METHOD FOR CONCRETION
To provide a manufacturing method for concretion using a solution containing calcium ion and a solution containing carbonate ion and hydrogen carbonate ion.SOLUTION: The present disclosure relates to a manufacturing method for concretion, the method comprises the steps of: filling a container, comprising a cylindrical body and a closing member that closes an opening at a lower end side of the cylindrical body and is permeable to a first solution containing calcium ions, with powder containing aggregate to form a powder layer; introducing the first solution into the inside of the container through the closing member by inserting the container into the first solution from the lower end side of the cylindrical body and immersing the powder layer in the first solution; and injecting a second solution containing carbonate ions and bicarbonate ions into the container from the opening at the upper end of the cylinder and precipitating solids inside the powder layer. The pH of the second solution is greater than 8.30.SELECTED DRAWING: Figure 1
【課題】カルシウムイオンを含む溶液と、炭酸イオン及び炭酸水素イオンを含む溶液とを用いた、コンクリーションの製造方法を提供すること。【解決手段】本開示は、コンクリーションの製造方法であって、筒体と、筒体の下端側の開口を閉塞し、カルシウムイオンを含む第一の溶液が浸透可能な閉塞部材と、を備える容器に、骨材を含む粉体を充填し、粉体層を形成する工程と、容器を、筒体の下端側から第一の溶液に挿入することによって、閉塞部材を介して第一の溶液を容器の内部に導入し、粉体層を第一の溶液に浸漬する工程と、筒体の上端側の開口から、炭酸イオン及び炭酸水素イオンを含む第二の溶液を、容器の内部に注入し、粉体層の内部に固体を析出させる工程と、を備え、第二の溶液のｐＨが８．３０超である、製造方法を提供する。【選択図】図１
