摘要
采用自然扩散法研究了氯盐溶液浓度、侵蚀时间和干湿循环影响粉煤灰混凝土固化氯离子能力的规律。结果表明:粉煤灰混凝土固化氯离子的能力随着氯盐溶液浓度的增大而逐渐增强,两者呈二阶多项式函数关系;随着氯盐溶液侵蚀时间的延长逐渐降低,两者呈幂函数关系;干湿循环提高了粉煤灰混凝土固化氯离子的能力。
TThe influence of solution concentration of sodium chloride, erosion time and dry-wet cycling on chloride ion solidiflcation capability of fly ash concrete was investigated by natural diffusion of chloride ion methods. The results indicate that the solidification chloride ion capability of fly ash concrete is reinforced gradually with increasing of solution concentration of sodium chloride, the relationships between the chloride ion solidification capability and solution concentration of sodium chloride is in second-order polynomial function; and the chloride ion solidification capability of fly ash concrete is decreased gradually with extending of erosion time, the relationships between the chloride ion solidification caPability and erosion time is in power function. Chloride ion solidification capability of fly ash concrete will be increased by dry-wet cycling action.
