Abstract
Cementitious grouts with and without polypropylene fibres were evaluat ed for use as containment barriers around waste landfills located in a n arid environment. Viscosity, flow time, water permeability and micro structure of the grouts were investigated. Low permeabilities of the o rder of 10(-11) to 10(-10) cm/s were measured on cement-sand grouts. P ermeability 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 fibres did not affect permeability signif icantly.
