| 摘 要： | 研究了粉煤灰细度对混凝土初始坍落度、抗压强度、碳化性能、干湿循环损伤的影响。结果表明粉煤灰细度提高,混凝土初始坍落度降低,抗压强度增大;碳化时间相同时,随着粉煤灰细度的增加。混凝土碳化深度不断减小;粉煤灰细度的提高加剧了混凝土干湿循环损伤的程度。

| Abstract: | Study of fly ash fineness on the initial slump,compressive strength,carbonation performance,wet and dry cycles results show that the fineness of fly ash increased,the initial slump of concrete decreased compressive strength increases:carbonation same time,with the increase of fly ash fineness.Decreasing the depth of carbonation of concrete:the fineness of fly ash concrete to improve wet and dry cycles increased the extent of damage. |
