Swelling Properties of Fly Ash Mixed with Bentonite
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 3
Abstract
The present study has been carried out to find out the swelling properties of fly ash and bentonite mixtures. Laboratory tests were conducted at different proportions of fly ash and bentonite. Fly ash is a naturally cementitious coal combustion byproduct. It is extracted by the precipitators in the smokestacks of coal-burning power plants to reduce pollution. Fly ash is cohesion less material and having very low compressive and shear strength however its strength can be inceased by adding low cost cohesive materials such as lime and clayey soil whereas bentonite is clay having high swelling properties when it comes in contact with the water. Major problem associated with fly ash is its disposal a large area of land required for disposal and toxicity associated with heavy metal leached to groundwater. The major objective of this study is to determine the swelling characteristics this mixture in order to use it in lining applications.
