Influence of Aquaculture Sludge on Volume Change Behavior of Expansive Clays

Nagaraju, T. V. / Sunil, B. M. / Chaudhary, Babloo

Aquaculture waste sludge (AWS) from the aquaculture ponds in the delta region of Andhra Pradesh is most popular. Intensive aquaculture practice involves usage of higher dosages of minerals and chemicals in the aquaculture ponds. Further, due to the intensive activity, there is a formation of AWS at the bottom of the ponds. In this study, experimental investigation was carried with various concentrations of ASW sludge was blended with the expansive clays. A summary of one-dimensional swell-consolidation studies on expansive clays blended with AWS is presented. Rate of heave, swell potential, and swelling pressure significantly decreased with the increase in ASW content. The paper also explores microstructural behavior of the expansive clays blended with AWS.
