An Experimental Study on the Effect of Plastic Waste Powder on the Strength Parameters of Tuff and Bentonite Soils Treated with Cement

This experimental study investigated the effect of plastic waste powder on strength and swelling behavior tuff bentonite soils treated by cement since is highly compressible does not absorb much water. aimed to improve used in construction adding various ratios (5, 10, 20, 25%) a low content (2.5%). Atterberg limit, consolidation, loading-unloading tests were performed determine optimal composition mixture. The results demonstrated that as increases, liquid limits, pressure, potentials, duration peak decrease. reduction particularly notable for soil with highest potential. Compression recompression indices increase significantly due its high compressibility. findings suggest can be utilized modification reinforcement material, but shouldn't alter compressibility
