The research on Temperature Control of Mass Concrete

The excessive temperature gradient are generated in the mass concrete construction of the most common and serious quality common fault,so the temperature control technology to ensure regular normal construction under the condition of using conventional materials has become an important issue.The graduation design on the mass concrete crack control by temperature control during construction period are studied,and combined with concrete dam during the construction has carried on the quantitative pouring piece temperature field simulation calculation and analysis,the design of hot areas is analyzed and the specific content is as follows: from the mechanism of concrete crack, temperature control measures and so on,qualitative analysis was carried out on the mass concrete temperature control;by comparing the temperature variation of different conditions it has been focused on the temperature field simulation analysis of the construction of concrete dam in the cold regions so that it has a more in-depth understanding of temperature changes of cold region on the impact of the dam.
