| Abstract | This experimental study covers primarily construction technique involved in the installation of lime columns and the evaluation of the load capacity in the A. I . T campus. Fourteen lime columns with an average lime content of 5, 10 and 15% were installed in the field with high Calcium hydrated Lime (Ca< OHl 2l as its stabilizer. Eight lime columns were load tested, with diameters of 0. 15 m and 0. 30 m. The lengths of the lime columns were 4, 6 and 8 m with curing period of 4, 6 and 8 weeks before load test were performed. The ultimate load ranges from 1 . 2 to 2. 4 ton, with the ultimate load of 2. 4 ton obtained from the 0 . 3 m, 15%, 8 m length column, cured over 8 weeks. This represented an increase of 2. 4 times over the ultimate load of the untreated soil. The effect of length, curing period, diameter and lime content were also investigated. Field vane shear and Dutch cone penetration tests were also performed to monitor the effect of the installation procedure and its relative effectiveness with lime stabilization. Laboratory test conducted on laboratory prepared samples and also those obtained from the field indicated the effectiveness of lime treatment which resulted in an increase in strength and lower compressibility with 1ime treatment. |
