Abstract
To provide a sheet and a system for curing concrete, in which the moisture amount to be used is small and which are able to reduce temporal and local variations in the moisture amount supplied to the concrete surface, a concrete curing method, and a method for producing a concrete structure. There is provided a concrete curing sheet of some embodiments of the present disclosure having a solid structure group on at least a first surface, the solid structure group having grooves defined between adjacent solid structures, and the grooves transporting water using the capillary phenomenon.
Claims5
A concrete curing method comprising the steps of:
- preparing a sheet having a solid structure group on at least a first surface, the solid structure group having grooves defined between adjacent solid structures, and the grooves transporting water using a capillary phenomenon;
- holding a state where the first surface of the sheet and the concrete surface face each other and water is interposed between the first surface of the sheet and the concrete surface;
- and
- removing the sheet from the concrete surface after the holding continues for a predetermined time.
A method for producing concrete structures, the method comprising the steps of:
- preparing a sheet having a solid structure group on at least a first surface, the solid structure group having grooves defined between adjacent solid structures, and the grooves transporting water using a capillary phenomenon;
- holding a state where the first surface of the sheet and the concrete surface face each other and water is interposed between the first surface of the sheet and the concrete surface;
- and
- forming cured concrete by removing the sheet from the concrete surface after the holding continues for a predetermined time.
