Experimental work has been undertaken to study the ceramic waste effect on mechanical and geotechnical properties of tuff treated by cement using a mixing ratio. This study aims at improving the tuff used in construction in addition of ceramic powder waste in the various ratios 5, 10, 15, 20 and 30%. Consistency limits, straight shear, odometer, compacting, compressive strength, sensitivity to water tests were performed to determine the mixture optimal composition. Then cement content was added to the optimized mixture to improve the mechanical characteristics. The results suggest that the mechanical and geotechnical indexes increase considerably with the ceramic powder content thus the ceramic powder can be used as a reinforcing material for tuff modification, but at content that does not significantly affect the compressibility of the mixture.
