Malaysia is a one of the developing countries where the constructions of infrastructure is still ongoing, resulting in a high demand for concrete. In order to gain sustainability factors in the innovations for producing concrete, geopolymer concrete containing granulated blastfurnace slag and ceramics was selected as a cement replacement in concret...

The utilization of waste materials which are abundant and cheap, especially from clean resources, has become more pressing than ever. This study investigates the influence of Oil Palm Biomass waste including the Palm Oil Fuel Ash (POFA), Oil Palm Kernel Shell (OPKS) and Oil Palm Fibre (OPF) on the compressive strength and chloride penetration of mo...

This research highlighted the behaviour of using bamboo ash as binder in geopolymer concrete against sulphate attack. Concrete has been using for a very long time ago as a construction material. Extensive studies on cement and sand replacement have been carried out over the year. However, the performances of bamboo ash as binder in concrete are not...

We report the effect of metakaolin (MK) substituted granulated blast furnace slag (GBFS) on the early strength of geopolymer mortars (GPMs) for potential repair applications. Such GPMs were prepared by activating MK (0–15%) replaced GBFS. Solution concentrations ratio of SiO2:Na2O were varied in the range of 1.08–1.26 to achieve appropriate geopoly...
