Abstract EN
High early strength is the most important property of pavement repair materials to allow quick reopening to traffic.
With this in mind, we have experimentally investigated geopolymers using low cost raw materials available in Thailand.
The geopolymer mortar was metakaolin (MK), mixed with parawood ash (PWA, rubberwood ash) or oil palm ash (OPA) as binder agent.
Rubberwood is often used as raw material for biomass power plants in Thailand, especially at latex glove factories and seafood factories, and burning rubberwood generates PWA.
Both PWA and OPA are therefore low cost residual waste, locally available in mass quantities.
The geopolymer samples were characterized for compressive strength, drying shrinkage, and bond strength to Portland cement mortar with slant shear test.
The experimental design varied the contents of PWA and OPA and the heat curing time (1, 2 and 4 h) after hot mixture process.
The hot mixture process resulted in very high early strength.
In addition, we achieved high compressive strengths, low drying shrinkage, and very significant bond strength enhancement by use of the ashes.
