In this study, a field test and a numerical calculation were performed on the temperature drop effect caused by low-temperature pouring to prevent thermal cracks in concrete dams. Firstly, a small spatial-scale temperature-gradient monitoring scheme was designed for concrete dams based on the ...
1.3.1The Variation of Temperature of Mass Concrete with Time Because of the large size, the variation of temperature in a mass concrete structure is shown inFigure 1.3; the placing temperatureTpis theconcrete temperaturejust after pouring. If the concrete cannot be completely cooled, it would be...

High curing temperatures can also be controlled when mass pouring with cooling pipes. The temperature when the concrete is placed can be somewhat controlled by using cold water for the mix, cooling down aggregates using ice, or pouring at night when temperatures are naturally lower. Concrete ...

Freshly placed concrete exerts pressure on formwork during the placing operation. It is influenced by the rate of placing and the air temperature. For instance, if the concrete pouring rate is too slow, setting of concrete starts to take place. As a result, the concrete at the...
