摘要
对大体积混凝土延迟钙矾石反应的评估是核电工程中对混凝土耐久性评价的重要方面。要想抑制大体积混凝土延迟钙矾石反应的发生,应针对具体环境下的特定混凝土配合比,通过开展前期模拟试验的方法来辅助分析确定避免发生DEF的具体技术要求。在任何情况下,大体积混凝土中心最高温度不宜超过80℃。
The proper evaluation of the delayed enttringite formation （DEF） in the mass concrete is an important index of the duration of mass concrete in the nuclear power plant construction. In order to control or minimize the delayed DEF in the mass zoncrete, the mix design of the specific concrete is evaluated. The preliminary test simulations are performed to find the techni- zal measures that minimizing the DEF, Under any condition, the highest temperature in the center of the mass concrete should not exceed 80 degrees celsus.
