Research in the field of geo-polymer materials -an ecofriendly material produced from waste material which is rich in silica and alumina such us fly ash- become massive issue for the last decades. Geo-polymer material and its application in construction industry still need to be explored in order to overcome the needs of green construction material for sustainable development. Since the research in the field of geo-polymer materials are growing fast nowadays, establishing forums for discussion, dissemination, and sharing knowledges are also important to conduct.
