1. The dry unit weight and optimum moisture of.Bentonite - lime mix increased with the addition of.Phosphogypsum.2. The dry unit weight of the reference mix decreased.And the optimum moisture content increased with The unconfined compressive strength of the.Bentonite increased with the addition of 8% lime.Beyond 8%, the unconfined compressive strength.Decreased.4. The unconfined compressive strength of the.Bentonite + 8% lime increased up to 8%.Phosphogypsum. Beyond 8% the unconfined,,Compressive strength decreased.5. The unconfined compressive strength of the.Reference mix increased with the addition of sisal.Fibers up to 1%. The trend was reversed after that.6. The unconfined compressive strength of bentonitelime -.Phosphogypsum increased with the addition of.Sisal fibers and with the increase in curing period.7. The improvement in post peak region was better for.The reinforced sisal fibers as compared to the.Unreinforced soil.8. The optimum value of, lime contentPhosphogypsum content and sisal fiber content in.Bentonite - lime phosphogypsum-sisal fiber mixtures.May be taken, as 8% 8%, and 1% respectively.
