An Experimental Study on the Practical Use of Cold Weather Concrete
한중 콘크리트의 현장 실용화에 대한 연구
Abstract
During the placement of concrete in cold weather, there are serious problems due to frozen concrete in the early stage. These adverse effects prevent the hardening of concrete. There are special mixing, handling, placement and crying to minimize problems. Heat crying and sheet curing have been used in crying steps in order to reduce problems. However, these curing methods are not efficient because it is hard to obtain the good quality and strength of concrete, and moreover, it needs additional works for curing. In this study, we evaluate the application of cold weather concrete by the dose antifreezing admixture in concrete mix design. Because it is easy to handle inconstruction site and improve the quality of concrete. As the result of this paper is to present a successful case for the practical use of cold weather concrete.
