  • Method for manufacturing concrete structure, concrete curing sheet for curing concrete
    Patent number: 9976314
    Abstract: A method for manufacturing a concrete structure comprises an installation step of installing a formwork 30 for concrete placement, a placement step of performing concrete placement in a state where a curing sheet 10 is attached to an inner surface of the formwork 30, and a demolding step of removing the formwork 30 after placement of concrete C. A contact angle of a contact surface of the curing sheet 10 for use in the placement step with water is 50 degrees or more, wherein the contact surface faces the concrete. Thus, generation of bleeding water is suppressed.
