Effect of paper sludge ash on the compressive strength of plaster of paris / paper sludge ash composites

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

In this study, paper sludge ash, a waste from pulp and paper industry was used as a filler in fabricating Plaster of Paris/paper sludge ash composites. Various percentage of paper sludge ash was used, namely 1 wt.%, 3 wt.%, 5 wt.% and 7 wt.%. The effect of paper sludge ash on the compressive strength of the Plaster of Paris was studied. The mixed powders of paper sludge ash and Plaster of Paris were form into a 6 mm diameter and 12 mm height cylindrical samples. The density decreased as the amount of paper sludge ash increased. The compressive strength of the composites also decreased from 11.67 MPa without paper sludge ash addition to 0.50 MPa at 7 wt.% paper sludge ash. However, the requirement of strength for Plaster of Paris in industry is between 8.96 MPa and 20.68 MPa. From SEM observation, sample contain higher percentage of paper sludge ash exhibited more porosity. Therefore the addition of 1 wt.% of paper sludge ash into Plaster of Paris can be a promising construction material.
