[0002] In the fields of hydropower and construction engineering, temperature control and maintenance of large-volume concrete pouring are particularly important. After the concrete pouring is completed, the problem of temperature rise in the warehouse surface of newly poured concrete in summer is particularly prominent. Data show that the temperature rise in the warehouse surface is the main source of temperature rise in newly poured concrete. The recovery value varies with the time from concrete entering the warehouse to covering the new concrete. Under general construction conditions, the time interval from concrete entering the warehouse to being covered is as long as 3 hours or more, and the temperature rise is large, which indirectly increases the maximum temperature rise of the concrete.
