Abstract: The objective of this investigation is to study water uptake during cyclic freeze/thaw exposure for mortar specimens submerged in salt solution. This is done the following way: At regular intervals during a freeze/thaw cycle, test specimens (5 mm thick, sawn discs) are removed from the salt solution, put on a scale to register the weight gain, and then put back into the salt solution. The experiment has been carried out with different test conditions and different mortar compositions. The results show that the water uptake during a freeze/thaw cycle consists of a reversible part and an irreversible part.
