Abstract
The release of carbon dioxide (CO2) during the production of cement and the increase in waste generation has allowed the construction to focus on sustainability by replacing cement with agricultural waste resources such as Palm Oil Fuel Ash (POFA) and Eggshell Powder (ESP). This experimental study focuses on developing sustainable foamed concrete incorporating high content of POFA and ESP as cement replacement with the aim of cement conversion, reduction in natural resources depletion, reduction of CO2 emissions and cleaner production. Cement was replaced using 30 and 35% POFA and 5 to 15% ESP by weight of cement. It was observed that the flowability decreased with the increase in the content of POFA and ESP; this is due to their ability to absorb water. It was also observed that 40% cement replacement achieved satisfactory compressive strength while the tensile stress loss was significant. This study confirmed that recycling and reusing of POFA and ESP are possible in foamed concrete which could be used for non-structural applications.
