引用本文摘 要：研究了混凝土的初始入模溫度、流動度和摻加粉煤灰等因素對混凝土絕熱溫升值和溫升速率的影響，同時還研究了所用膠凝材料的水化動力學。研究結果表明，提高混凝土初始入模溫度將加速膠凝材料的水化，并縮短水化反應持續時間。這對低強度等級混凝土所用膠凝材料的水化程度影響不大，因而對其絕熱溫升值影響不顯著；但卻會明顯降低高強度等級混凝土所用膠凝材料的水化程度，使其絕熱溫升值下降。摻加粉煤灰或改變混凝土的工作性也會影響混凝土的絕熱溫升值和溫升速率。 Abstract: The influences of initial casting temperature and fluidity of concrete, and whether adding of fly ash, on the adiabatic temperature rise and its rising rate of concrete were studied. And the hydration kinetics of binders was discussed based on the results of tests. The rezults show that with increasing the initial casting temperature of concrete, the hydration of binder is accelerated and the duration of hydration is shortened, which will show little effect on the hydration degree of binder for low strength grades of concrete, so that there is almost not effect on adiabatic temperature rise. 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. Besides, the adiabatic temperature rise and the temperature rising rate of concrete will be influenced when adding fly ash or modifying the worability of concrete.
