The Utilisation Of Wood Ash As Alkaline Activator For Ambient Cured Geopolymer Concrete

The blended hybrid geopolymer concrete utilising industrial waste ash is a new option of constituent binder material to replace ordinary Portland cement (OPC) concrete. It has a significantly reduced carbon footprint and has a positive impact on the environments. Furthermore, blended hybrid geopolym...

The Utilisation Of Wood Ash As Alkaline Activator For Ambient Cured Geopolymer Concrete
description The blended hybrid geopolymer concrete utilising industrial waste ash is a new option of constituent binder material to replace ordinary Portland cement (OPC) concrete. It has a significantly reduced carbon footprint and has a positive impact on the environments. Furthermore, blended hybrid geopolymer concrete proposed to resolve the conventional geopolymer binder issues associated with a high dosage of alkaline activator and elevated curing temperature that hindered the industrial application of geopolymer binder. The study was conducted with the primary aim to hybridise industrial waste ash namely pulverised fuel ash (PFA), ground granulated blast furnace slag (GGBS), high calcium wood ash (HCWA) and silica fume (SF) with suitable alkaline activators to produce binder for concrete.
