Abstract
Cement manufacturing industry is a critically important industry in India and throughout the world. After the industrial revolution, different types of by-products are produced which pose serious threat to the environment. Cement kiln dust (CKD) is one such material generated by the cement industry. Over the past few years pronounced advances have been made in the management of CKD. Using such material in civil engineering works is a smart way to dispose it off in an ecofriendly manner. In this paper, silty soil (ML) was treated with different amounts of CKD. Compacted specimens were tested for unconfined compressive strength for different curing time of 1, 3, 5, 7, and 9 days and the results indicated a substantial gain in strength. Specimens with the addition beyond 10% yielded high strength but exhibited brittle character. Although many researchers have been reported pertaining to the use of CKD after mixing in the soil but in this study, the potential benefits of reinforcing weak ground by the inclusion of soil-CKD layer have been investigated experimentally. Tests were conducted by considering various parameters such as CKD content, curing period, depth and thickness of soil – CKD layer. The results validated that the inclusion of soil-CKD layer increased ultimate bearing capacity of footing. At 10% of CKD and 7-day curing age of stabilized soil-CKD layer, the bearing capacity increased is about 118.75% at a depth of 0.4B, where B is width of footing.
