Abstract
In recent years, large volume concrete has been applied more and more in water industry building and civil engineering. With the rapid development of modern science and technology and economic society, massive concrete is widely used in high-rise buildings and large equipment found-ation, take effective measures, ensure the quality of mass concrete in the construction process is very important. Mass concrete because of cement consumption, large temperature difference between inside and outside, the temperature shrinka-ge is easily led to cracks in reinforced concrete. The formation of cracks in concrete wil directly affect the quality of the project.Therefore, consideration must be given to the constru-ction of large volume concrete construction control of thermal stress and crack prevention measures.关键词
