Experimental study of fly-ash migration in sands of various particle size distributions

Original language description

Fly-ash migration in three sands of various particle size distributions and consequently various porosities, was studied in the laboratory. First, sands were packed in glass cylinders with diameters of 5.52 cm and heights of 18 cm. Secondly, sands were packed in plastic cylinders with diameters of 30 cm and heights of 40 cm. The fly-ash was applied on the top of all cylinders followed by pulse infiltrations. Visually observe and gravimetrically evaluated fly-ash migration on small cylinders correspondedto fly-ash mobility in large columns detected magnetically using the SM400 Kappameter that measured increasing magnetic susceptiblity in depth with incrasing amout of fly-ash, which contains ferimeagnetic particles. While the fly-ash migrated freely thought thecourse sand material, in the other two sand materials the fly-ash moved to the depths of 10-12 adn 4-6 cm in the medium and fine sande, respectively, due to the pore-scape blocking and water flow decrease.
