Compressive Strength Characteristics and Volume Change of Sewage Sludge Matrices Solidified by a New Binder

Abstract:

The disposal of sewage sludge is an important issue in practical engineering. This study proposes a new method of solidifying sewage sludge with stone material waste and portland cement. The effects of mass ratio were discussed by the investigations of unconfined compressive strength and volume change of the solidified samples for different curing time. Experimental results show that the binders appeared effective for improving the strength of matrices. it was also found that the volume capacity of matrices increased little, which is important to municipal solid waste disposal. Overall, the work suggests that stone material waste can be utilized as a substitution material for cement to reduce the cost of sludge disposal.
