Filtration of silica particles from a low-pH cementitious grout
Graphical abstract Display Omitted
Highlights We investigated filtration of low-pH fresh grout based on cement and silica fume. There is no significant separation between cement and small silica fume grains. During filtration the grout will lose mainly its water and the ions in this water.
Abstract Spent nuclear fuel is stored in rock depositories. Swelled bentonite around the stored capsules prevents eventual spread of radioactive material by ground water. The pH-value of the ground water in contact with bentonite shall be less than 11 not to affect the swelling capacity of the bentonite. Therefore cementitious grout with low pH-value is used to grout these depositories. There is a risk that pH-value of this grout can locally increase due to filtration at fracture constriction and influence pH-value of ground water. Chemical SEM–EDAX-analysis indicates that there is no risk of increasing of PH-value in this grout.
