When strength and bearing capacity of soils are inadequate, stabilization with chemical admixtures is a commonly preferred method, which ensures satisfactory engineering properties. In this study, pozzolanic cement, lime and class C fly ash were used as admixtures for stabilization. Effects of clay content, admixture inclusion level, additive content and curing period were investigated on strength of sandy soil with different bentonite contents. Mixtures including 4, 8, 12 and 16 % bentonite by weight were stabilized with 3, 6, 9 % pozzolanic cement, lime and also 5, 10, 15, 20 % class C fly ash by weight at their optimum water contents. Specimens were then subjected to unconfined compressive strength testing after 1, 7 and 28 days of curing period. Experimental results revealed that, maximum and minimum strength was obtained by testing specimens including pozzolanic cement and fly ash, respectively. It is evident that, economic and environmental concerns makes use of fly ash more feasible. </font> </span> <br /> </p>}, number={3}, publisher={Manisa Celal Bayar Üniversitesi}
