Abstract: This paper based on the example of a basement in the constructed building which has its concrete poured and temperature controlled.And then it expounds that the works on pilot calculation of temperature-controlling should be executed during the construction plan of mass concrete.When the 2.2 m thick mass concrete of the raft shape foundation is constructed at daily mean temperature 22 ℃,the curing method of adopting heat insulation and wet retaining and storing water on the surface of the concrete is feasible.The heat difference between the inside and the outside of mass concrete can be controlled below 25 ℃ and there are no temperature cracks.Moreover the long concrete wall with concrete formwork,which preserves temperature curing and puts on reserving post-pouring belts reasonably,is the key to the crack-preventing of wall.The temperature-controlling indexes are estimated of the raft foundation and the long concrete wall,which provide a theoretical basis for the smooth construction of concrete structure.
