近年来,越来越多的大体积混凝土在水工建筑物以及土木工程领域得到应用.随着现代科学技术和经济社会的快速发展,大体积混凝土广泛应用于高层建筑结构和大型设备基础,采取有效措施,确保大体积混凝土的质量在施工过程中显得尤为重要.大体积混凝土由于水泥用量多,内外的温差大,引起温度收缩,很容易导致钢筋混凝土裂缝.混凝土裂缝的形成将直接影响工程质量.因此,必须考虑到施工的大体积混凝土结构热应力控制和防裂缝措施.

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.
