The study aimed to develop a time-dependent model for determining the chloride binding capacity of concrete with crystalline material under different conditions. The model, based on experimental analysis, showed satisfactory agreement with the predicted values falling within the R-squared values ranged from 0.842 to 0.982.
The aim of this study is to develop a time-dependent model for determining the chloride binding capacity of concrete with crystalline material (CM) with different water to binder (w/b) ratios, fly ash replacement proportions, curing times, and chloride exposure periods. The effect of CM on chemical and physical binding processes was considered in the development of the model. The model was developed based on the results of experimental analysis conducted by the authors. The values of chloride binding capacity predicted using the model fell within the R-squared values ranged from 0.842 to 0.982, which indicates satisfactory agreement with the experimental results.
