ABSTRACT:
An improved stable, clay/cementitious composition comprised of 15%-55% Attapulgite clay and 85%-45% slag cement particularly useful in the construction of very low permeability, self-hardening slurry trench cutoff walls, has been discovered. The aqueous slurries of the invention exhibit (1) an initial viscosity controllable without the addition of chemical, (2) lower filtrate loss and (3) chemical resistance, (4) lower permeability on curing, and (5) expedient handling.
