Fly ash, bottom and bentonite have potential to be used as geopolymer precursors, because they contain high silica alumina. Until now there has been no research that combines these three materials materials. This aims incorporate an aluminosilicate source in the fly ash based geopolymer. Geopolymer concrete was made by mixing alkaline activator, aggregate (gravel), superplasticizer, water. The ...

Using geopolymer in soil stabilization has gained much attention recently due to its efficiency improving properties and being environmentally friendly at the same time. This research aims investigate effect of palm oil fuel ash (POFA)-based on soft stabilization. The mechanical microstructural performance two types clay treated with produce from POFA material was focus this study. In respect, ...

The use of fly ash wastes as inexpensive sorbents, mostly for heavy metal cations, is one method recycling the millions tons waste produced each year. In this paper, a ash-based geopolymer was used an adsorbent Cu2+ and Cd2+ from aqueous solution. To improve sorption efficiency, modified by incorporating titanium oxide (TiO2) nanoparticles that were synthesized hydrothermally annealed at temper...

Municipal solid waste incineration (MSWI) fly ash is classified as hazardous and needs to be disposed of according strict regulations. By disposal, valuable resources in the MSWI lost, other solutions are sought for. The effect electrodialytic remediation (ED) a pre-treatment for removing heavy metals from before using treated geopolymerization with coal was explored. ED increased Si reactivity...

Despite the increasing number of studies on geopolymer-based materials, a lack information still prevails concerning use geopolymer materials for consolidation and conservation built heritage. Since introduction term “geopolymer” by Davidovits, several have pointed out geopolymers as potential replacement traditional binders, mainly due to their advantages associated with mechanical properties ...
