Based on the above analytic solutions, the equivalent model for temperature field is established by merging multiple rolling layers into one composite layer, and the approximate formulas for equivalent initial temperature and equivalent adiabatic temperature rise are put forward.
然后以此解析解为基础,合并多个碾压层为一个浇筑层,建立了温度场等效模型,并给出了复合浇筑层的等效初始温度和等效绝热温升的计算方法。

In addition, it was able to confirm an effect to reduction of adiabatic temperature rise and improvement of fluidity of concrete.
此外,粉煤灰和石灰石替代部分水泥还能减小混凝土的绝热温升、改善其流动性。
Meanwhile, the strength performance of HBCC inside the dam was studied by simulating the adiabatic temperature rise of dam concrete.
同时,模拟大坝工程内部混凝土的绝热温升变化规律,研究大坝内部混凝土的实际强度性能。
However, the hydration degree of binder, as well as the adiabatic temperature rise for high strength concrete, will be obviously decreased due to the increase of initial casting temperature.
但却会明显降低高强度等级混凝土所用胶凝材料的水化程度,使其绝热温升值下降。
