Abstract
The structural analysis of the application of quarry dust (QD), crushed waste ceramics (CWC), palm
bunch ash (PBA), crushed waste ceramics base geopolymer cement (CWCbGPC) and palm bunch
ash base geopolymer cement (PBAbGPC) in the treatment of soil has been studied. The need to
encourage the use of supplementary cementing materials in construction works is of great necessity.
This is because of the further damage the emission of CO2 is causing and its contribution to global
warming. Laboratory experiments have been adopted to investigate the behaviour of test soil on the
addition of admixtures. After the preliminary study, it was shown that the test soil was an A-7 soil
according to AASHTO classification system and poorly graded soil of high clay content (GP/CH)
according to the USCS. The treatment protocol was used to study the consolidation settlement (CS)
of the treated test soil and results showed that the CS reduced steadily at the varied addition of the
cementing additives. A more remarkable improvement was recorded with the geopolymer cements
(GPC). The results equally showed that the PBAbGPC was observed to be better than the
CWCbGPC in the treatment protocol. The exercise not only achieved the ridding the environment of
solid wastes but showed that these waste materials could be reclaimed and synthesized into
alternative cementing materials to replace ordinary Portland cement and remove its attendant CO2
emission and the global warming effects from the atmosphere.
