Abstract

This research investigated the potential for utilization of dewatered sludge from wastewater treatment plants of the pulp industry to produce fiber-cement composites. The sludges were from the bagasse and eucalyptus pulp industries. Moisture content, bulk density and flexural strength of the fiber-cement composites were determined at the age of 14, 21, 28 and 60 days. Experimental results showed that moisture content of the fiber-cement composites containing both types of sludge increase with increasing fiber content and curing duration whereas, density decreased with increasing fiber content from 5 to 7.5%. In addition, flexural strength of fiber-cement composites containing eucalyptus sludge was higher than those containing bagasse sludge at every curing duration observed.
