The integral casting technology of the mass concrete can reduce the work-period. The most important control point of the technology is to eliminate cracks form the temperature stress and shrinkage of the concrete by the design of concrete mix proportion, the selection of admixtures, the arrangement design of the cooling pipes, temperature control and the casting maintenance of concrete to make concrete structure integral, safe and reliable.
