AI Technical Summary

Technical Problem

Existing curing formwork systems fail to objectively confirm moisture supply to the entire surface of concrete during curing, leading to potential uneven moisture distribution and increased risk of shrinkage and cracking.

Method used

A concrete curing device comprising a formwork main body with a wetting portion and a condition confirmation portion, which can be transparent or sensor-based, to ensure uniform moisture supply and monitoring, along with a water supply mechanism to maintain the concrete surface in a wet state without dismantling the formwork.

Benefits of technology

Ensures uniform moisture distribution, enhances concrete strength by preventing drying shrinkage and early cracking, and accelerates curing by maintaining a moist environment during the early stages of concrete setting.

Abstract

To provide a means capable of objectively confirming that moisture is supplied to the whole surface of concrete in a curing process of the concrete.SOLUTION: This curing device is provided with at least a form body part 10, a wetting part 20 arranged on a surface on the concrete A side of the form body part and having at least water permeability, and a state confirming part 30 capable of confirming a wetting state of the wetting part. A permeable material constituting a part or the whole of the face material 11 constituting the form body part, or a sensor arranged in the form body part or the wet part can be used for the state confirming part. The face material 1 can be provided with a communication hole 13. After the concrete A is placed, surplus water and / or air generated from the concrete is discharged to the outside of the form through the wetting part, and after the concrete is set, water is supplied to the wetting part without disassembling the form, and the concrete is cured while confirming that the surface of the concrete is in a wet state by the state confirming part.SELECTED DRAWING: Figure 1
