If constant is selected, the model will assume that the surface chloride ion concentration remained constant throughout the life of the structure and is equal to that measured at the time of sampling. If Linear is selected, the model assumes that at time = 0, Co = 0, and Co increased to the value at the time of sampling linearly.
