Soil strength development involves the process of improving geotechnical properties of soil. There are thousands of industries growing in many countries like in India, in which industrial waste become a serious problems. In those industries paper mill industry is one of them, which produce thousands of tones waste material every year. Utilization of this waste material in required civil engineering area can be proved a good additive in construction. Waste Paper Sludge (WPS) is a lime sludge

... age material come from Paper Industry generally dumped into sites around the Industries. 2 %, 4 %, 6 %, 8 % and 10 % Waste Paper Sludge (WPS) added to the soil and conducted test for analysis of strength properties of soil. Laboratory experiments results showed that 6 % is the optimum percentage of Waste Paper Sludge (WPS) which is mixed in the soil for obtained higher strength. In civil engineering construction like Railway lines, Highway Network, Airport Runways etc are required a good strength of soil embankment, where Waste Paper Sludge (WPS) become a good additive for improving strength of soil.
