摘要
研究了粘土烧结砖吸湿膨胀的动力学特性,揭示出作为粘土烧结砖吸湿膨胀过程中激活能源的过热饱和水蒸气的能量与绝对温度之间的关系,测试了两类粘土烧结砖吸湿膨胀过程所需激活能的大小,推导出其激活能并不是一个常量,但其平均值约为:70kJ/mol～75kJ/mol。
The paper researches on dynamics characteristics of moisture expansion for fired clay brick; reveals the relationshape between the energy and absoluted temperature of saturated overheated vapor for activation energy needed in moisture expansion for fired clay brick; tests the activation energy needed in moisture expansion for two kinds of clay brick; finally derives that the activation energy is not a constant, and its average value is 70 kJ/mol - 75 kJ/mol.
