Abstract:
Cooking coal dust has the potential to replace traditional
admixtures used to improve soil properties. The low cost of
this coal dust is an added benefit as it can be used either
alone or in combination with regular admixtures in the
construction of foundations, embankments, retaining walls
etc. The aim of this paper is to determine the shearing
strength parameters of Pilani soil mixed with varying coal
dust amount. The experimental values will give us a better
understanding of the range of coal dust usage in
construction. Disposal of the huge amount of produced
coal dust poses a potentially serious environmental threat
due to paucity of land for disposal. Therefore, using coal
dust in construction can, in addition to reducing
expenditures, will also solve the headache of its safe
disposal and help in preventing environmental degradation.
Direct shear testing was conducted at in-situ water content
& at OMC conditions.
