ZELIAC is a non-hazardous material made of naturally existing, low-cost ingredients.
Maximum reduction in dispersivity occurred at 8% ZELIAC, which is the fixation point.
Curing time was significant; after 28 days the dispersive soil became non-dispersive.
UCS has increased 7.3 times through the addition of 8% ZELIAC and 90 days of curing.
ZELIAC not only improved the properties of dispersive clay, but also is non-hazardous.
