Lime Stabilization on Soil of a Selected Reclaimed Site of Dhaka City

Author(s): M. A. Ansary and K. A. Hasan
Keyword(s): Stabilization, lime content, moisture-density relation, unconfined compressive strength, CBR, flexural strength and flexural modulus
Abstract: Engineering properties of a lime stabilised soil collected from a reclaimed site of Dhaka, Bangladesh was studied. The soil used in this investigation is high plasticity silty clay with liquid limit of 52 and plasticity index of 29. Compaction tests, unconfined compression tests on compacted large cylindrical samples (71 mm diameter by 142 mm high and compacted according to Modified AASHTO compaction test), California Bearing Ratio (CBR) tests and flexural strength tests using simple beams with third point loading were carried out on the untreated samples and samples stabilised with different lime contents (1%, 3%, 5% and 7%). Effect of curing age on unconfined compressive strength and flexural strength was also investigated for the stabilised samples. From compaction tests, it was found that with increase in lime contents maximum dry density reduced and optimum moisture content increased. Considerable increase in compressive strength was found due to stabilisation, which depended on the lime content and curing age. CBR valuesof the stabilised samples increased significantly. Flexural strength of soil-lime beams also increased.

Prof A. M. M. Safiullah

Warm greetings to BSGE members, well wishers and patrons. Thanks for your continued support in BSGE activities all through the years since formation of the society in 1989. I hope BSGE activities will be facilitated with this updated web page. Let's make it an effective means for communication and information sharing among our fellow members and geotechnical professionals/organizations at home and around the world. With the increase in infrastructure development in Bangladesh we have to face new geotechnical challenges in the coming years. I would request the civil engineers, academicians, contractors, geotechnical firms and all others relevant to the geotechnical engineering profession in the country for increased interaction through BSGE to develop and maintain standards so that we can face these challenges in a professional way
