To provide a curing method for concrete or mortar which makes it possible to reliably develop the desired strength in placed concrete or mortar without causing cracks and the like.SOLUTION: A concrete or mortar curing method in which, placed concrete or mortar is pre-cured, followed by covering at least one surface of the concrete or mortar with a heat supply curing layer, and applying heat by the heat-supply curing layer for curing. The heat supply curing layer is formed by laminating a wet mat having a water retaining function and a heat supply mat having a temperature adjusting function, and the wet mat is arranged in contact with the concrete or mortar.SELECTED DRAWING: Figure 1 【課題】打設したコンクリート又はモルタルにおいて、ひび割れ等を生じさせることなく所望の強度を確実に発現させることの可能な、コンクリート又はモルタルの養生方法を提供する。【解決手段】打設後のコンクリート又はモルタルを前養生した後、前記コンクリート又はモルタルの少なくとも一面を給熱養生層で被覆し、前記給熱養生層により給熱して養生するコンクリート又はモルタルの養生方法であって、前記給熱養生層は、保水機能を有する湿潤マットと、温度調整機能を有する給熱マットを積層してなり、前記湿潤マットを、前記コンクリート又はモルタルに接して配置する。【選択図】図１
