Godong expansive soil stabilization using sugar cane and sikacim concrete additive

his research was carried out to analyse the expansive soil sample obtained from Godong, Purwodadi with the addition of sugar cane at 0%, 2.5%, 5%, 7.5% and 10%. The soil (water content, specific gravity, hydrometer, and Atterberg limits), and mechanical properties of Swell Test (Oedometer) and CBR (California Bearing Ratio) were tested, which obtained 93.65% LL (liquid limit), 31.08% PL (plastic limit) and 62.57% IP (plasticity index). While a fine fraction sieving size <0.075 mm (90.48%), and coarse fraction of 0.075 mm (2.16%) were obtained. Also, the addition of sugar cane increases the soil properties of LL and PL, and decreases its IP. It also affected the values of the soaked and unsoaked CBR with a steady increase at 7.5% and decrease at 10%. But not capable to improve soil shrinkage.
