AI Technical Summary
Technical Problem
Underwater concrete curing is challenged by temperature fluctuations affecting the strength development of ultra-high strength reinforced concrete products, particularly in winter, and existing heating methods are costly and labor-intensive.
Method used
A floating insulating material composed of granular materials or mesh bags containing granular materials is used to cover the curing water surface, providing thermal insulation and reducing temperature fluctuations, which can be easily installed and removed.
Benefits of technology
The insulating material effectively maintains curing water temperature, reducing energy consumption and labor costs while facilitating easy installation and removal, ensuring consistent concrete strength development.

Abstract
To provide a heat insulating material for concrete curing, a method for curing concrete in water, and a method for manufacturing a concrete product, in which the water temperature of curing water is hardly affected by the outside air temperature, the installation and removal of the heat insulating material are easy, and the concrete product can be easily taken in and out of the curing water.SOLUTION: The heat insulating material 1 for concrete curing is a plurality of granular materials 2 floating on curing water 4 of a concrete curing pool 3, desirably contains at least two kinds of granular materials having the maximum particle size, and may be a plurality of net bag bodies including the plurality of granular materials 2. The heat insulating material 1 for concrete curing is floated on the curing water 4 of a concrete curing pool 3 to cover the surface thereof to cure a concrete product 5.SELECTED DRAWING: Figure 1
