Abstract

Desiccation crackingis a widespread phenomenon in clay soils which may significantly increase the hydraulic conductivity of soil. This problem is one of the main concerns in the design and construction of landfill covers, particularly in barren regions. Tests were conducted to investigate the effects of nano-alumina on the desiccation cracking of four soil samples of different plasticity index. Surficial dimensions of cracks in the soils were monitored and quantified using the crack intensity factor (CIF). The results showed that the required amounts of nano-alumina mixed with soil were very low, which give a little increase in maximum dry density. Furthermore, it was observed that the optimum water content, volume change and crack intensity factor of soil specimens decreased measurably with addition of these low amounts of nano-alumina particles. This will generally decrease the development of cracks in the soil and thus reducing its hydraulic conductivity.
