Abstract: Concreting conditions was specific in cold air because in cold weather, concrete setting and coolness of concrete is delayed and it is possible that low amount of cement paste is broken due to the formation of ice and considering the above issue, determining the time to start concrete curing is very hard and determining the age of concrete in that age, the concrete is very resistant against freezing, is hard. Thus, it is required to do some cautious measurements during casting, finish, curing, operation and concrete fixation in cold weather. The contractor should consider the protection against cold weather before delivering his proposal. Because if it is not so, the costs of corrective methods and controlling regulation plans including modeling and re-calculation of the structure based on the existing resistance and using additives to achieve better results are the responsibility of contractor. In this study, the required strategies to cope with cold air to achieve the required results and optimized operation by considering ideal conditions of workers are required.
