Mitigating desiccation cracks in clay using sustainable additives

Desiccation cracking in clay is a major unwanted problem in geotechnical and agricultural applications. Hotter and drier weather conditions induced by climate change aggravate the formation of cracks. The problem of cracking is predominant in reactive soils and affect the structural integrity of clay soils and structures built on them. This project aims to find sustainable solutions to control desiccation cracks by reinforcing clay soils with additives. The potential additives should enhance the tensile strength of soil, improve water retention, be durable and environmentally friendly. The project will investigate innovative materials as additives and incorporate variety of testing methods to develop solutions.
