Effect of porosity on the shrinkage behaviour of Ukpor and Nsu clays

Abstract

The paper describes the effect of porosity on the shrinkage behavior of clay, pellets and briquettes of different porosities. The result of the investigation indicates that shrinkage which is a major cause of rupture in fired clay in creased with decrease in porosity. It was also discovered that the porosity of pellet/briquette plays important role in controlling and determining the shrinkage index of the pellet.
