2020-6-1Sewage sludge Ash SSA is a waste material obtained from the incineration of waste water sludge. The SSA generated from the burning usually is disposed of to the landfill which is not the final solution. Hence an investigation was carried out to study the potential use of SSA in cement base material. The chemical mineralogical characteristic of SSA in cement mortar were examined.

2015-10-1Waste paper sludge ash WPSA Waste paper sludge was obtained from JML waste paper corporation, Pathankot, Punjab, India. It was then sun dried and incinerated so as to convert it into ash. The ash was sieved through 90 micron 0.0035 Indian Standard sieve. The specific gravity of waste paper sludge ash was found to be 2.6.
