Abstract

The strength of fly ash-electroplating waste- cement mix were determined by undrained unconsolidated (UU) triaxial shear tests conducted on cylindrical specimens of diameter 39 mm and length 84 mm, prepared for fly ash and different co mbination of fly ash-waste sludge-cement mixes. The tests were carried out at different curing periods of 7, 28 and 90 days. The shear strength parameters and undrained shear strength of fly ash and mix blends were determined. The outcome of the test results was quite encouraging in terms of undrained shear strength and shear strength parameters. The maximum gain in shear strength was obtained at 90 days of curing for the mix 47%FA+45%S+8%C (2.48 MPa) as compared to fly ash (0 .10 MPa) for the same curing period.
