The effect of nano POFA and nano eggshell powder to hardened concrete propeties
Malaysia is one of the main crude palm oil producer and exporter in the world. Meanwhile, a million tonnes of agro wastes such as palm oil fuel ash (POFA) and eggshell (ESP) is being produced every year and it causes a problem in disposing of POFA and ESP. However, POFA and ESP have the high potenti...

Malaysia is one of the main crude palm oil producer and exporter in the world. Meanwhile, a million tonnes of agro wastes such as palm oil fuel ash (POFA) and eggshell (ESP) is being produced every year and it causes a problem in disposing of POFA and ESP. However, POFA and ESP have the high potential to be used as recycling construction materials in the production of concrete as it contains a high content of silica and calcium which possesses pozzolanic behaviour. For strength activity index of POFA and ES. Pozzolanic materials in concrete works are increasing, and are expected to continuously increase in the years ahead because of technological advancement and the desire for sustainable development. Concrete containing raw material is introduced to reduce the cost of the construction project by reducing the use of materials and formworks. Nano palm oil fuel ash and Nano eggshell powder has been treated and can be used as a partial replacement for cement in concrete due to its pozzolanic effect. The main purposes of this study are to investigate the effect of Nano POFA on concrete properties replacement as cement also to investigate the effect of Nano POFA with NESP on concrete properties replacement as cement improving the strength of concrete.
