This paper discusses the validities of insulating curing of cold weather concreting at early stage by applying insulation forms. Tests were carried out using modified insulating form combining existing insulating form and various other insulations in order to develop improved insulation form. Temperature history of concrete using various insulating forms and insulation was measured to determine most effective combination of insulting form. According to results, as for the wall form, under the curing temperature of -1, the temperature of concrete using Euro form drops sharply before 24 hours and lasts below for 7 hours. The temperature of concrete using the form combining Polypropylene panel, styrofoam and plywood panel keep above . And, it is confirmed that the form mentioned above has a favorable effects on enhancing strength development of concrete and the cost to make the forms shows more reasonable than that of existing forms. However, as for the combination methods of insulation form for slab, which is composed of insulating form at the bottom of slab and various surface curing materials at the top of slab, in case of exposed condition at the top of slab, temperature history of concrete goes below after 10 hours. In case of the combination of vinyl sheet and curing blanket, it drops below after 42 hours. However, in case of the combination of vinyl, styrofoam and curing blanket, it does not go below until 55 hours. Accordingly, compared to the case of exposure and the combination of vinyl and curing blanket, it indicates that the combination mentioned above has more effective insulating performance.
