It is important to understand the curing methods of the high fluidity concrete and various properties in winter from the point of the plan as the construction. Therefore, we examined the high fluidity concrete that used admixtures such as binding agents, segregation reducing agent by using the large model test specimen. As results, the heat curing is effective means to obtain prescribed strength at the early age in the winter concrete construction. However, attention is required for the curing period and the state of moist at the heat curing. The freezing and thawing resistance decreases according to an initial the curing methods occasionally. The finding obtained by the experiment can be reflected in the construction plan.
