Abstract[Bearbeiten]
Here we report results from an initial study on salt solution movement within masonry sandstone. The capillary uptake of 6M calcium iodide solution into Blaxter and Locharbriggs sandstone was imaged by micro computed tomography scanning at three minute intervals. Over a scanning period of seven seconds/360o scan, the solution movement was successfully visualised and quantified. Results show distinct differences in the uptake characteristics of Blaxter and Locharbriggs sandstone. Flow is dominant within permeable layers in the Locharbriggs samples forming thin layers, coating grains that permit the movement of solution without filling pores. It is thought that preferential flow through these confined permeable layers may be an important determinant of salt crystallisation processes.
