Geopolymer gained their maximum adhesion within first three days. After 3 days curing on 60oC resulted into a maximum adhesion strength of 10MPa at Si/Al=3 and Na/Al=1.0. Micro structural analysis and Infra red spectroscopy was used to study the geopolymerisation process. Surface profile of fly ash particles shown that degree of reactivity has a direct relation with their surface roughness. {\^A}{\copyright} 2014 Trans Tech Publications, Switzerland.}, author = {Irfan Khan, M. and Azizli, K. and Sufian, S. and Man, Z.}, issn = {16609336}, isbn = {9783038351818} }
