The chemical waste landfill at Sandia National Laboratories in New Mexico is to be remediated as part of the Mixed Waste Landfill Integrated Demonstration sponsored by the US Department of Energy. The major concern at this landfill is detected migration chromic acid and chromic sulfuric acid solutions were disposed. It is planned to stabilize chromium, place low permeability vertical and horizontal subsurface barriers for containment and finally, cap the landfill. The aim of the remediation is to reduce chromium migration to environmentally acceptable levels in a cost-effective manner. Cementitious grouts with and without polypropylene fibers were evaluated for use as containment barriers around waste landfills located in an arid environment. Viscosity, flow time, water permeability and microstructure of the grouts were investigated. Low permeabilities of the order of 10[sup [minus]11] to 10[sup [minus]10] cm/s were measured on cement-sand grouts. Permeability was influenced by curing conditions and water/cement ratio. Variation of sand/cement ratio by mass from 1 to 1.2 and addition of 0.1 to 0.2% volume fraction fibers did not affect permeability significantly.
