Abstract :

Soil has the most important role for any civil engineering project as it is the most basic foundation for it. The soil is required to bear the loads coming on it without failure, but not necessarily it happens in all the cases, as, it may be weak in some regions. There are many methods available for the stabilization of soils with materials like cement, lime as additive, chemical stabilization. Further, for achieving goal of sustainable development with environmental and economic issues, various waste materials like kiln wastes, plastic wastes and industrial wastes, etc have caught the eye of researchers in the past, say, like utilization of waste brick dust or surkhi/brick kiln dust is helping the motives by elimination of solid waste problem. So, local weak soil stabilized with surkhi/brick kiln dust- cement first and further, an effort has been made in this study by introducing the fibers as polypropylene fibers randomly mixed to surkhi/brick kiln dust-cement stabilized soil and checking the properties like compaction properties; Unconfined compression strength (UCS), California bearing ratio (CBR) afterwards, expected to be improved further due to tensile inclusions incorporated into soil. The CBR value is expected to increase with inclusion of such fibers on surkhi/brick kiln dust- cement stabilized soil, helping decreasing the design thickness of subgrade at desired strength based on specifications, and hence, decreasing the overall construction cost with theme of sustainable development maintained. Samples with varying surkhi/brick kiln dust- cement content were prepared prior to testing and the content of same giving best results were further subjected to polypropylene fibers dose at the random to check the impact of same to improved soil. Experimental results indicate there is a significant improvement in properties of soil like California bearing ratio (soaked and unsoaked), Unconfined compression strength at worked compaction levels. In extensive series of tests were carried out but due to time constraint only one type of fiber at random was used on the improved soil. Hence, more researches are needed to be executed with different type of fibers to observe the behavior of such soils.
