Foamed concrete is a controlled low-density concrete, and due to its excellent thermal insulating acoustic absorption properties, application has been on steady rise. Palm Oil Fuel Ash (POFA), an agricultural waste generated by the industry Eggshells, causes many environmental problems. The pozzolanic nature of POFA high calcium oxide content in Eggshell Powder (ESP) are components that contribute their suitability as partial cement replacement concrete. This experimental work studied flexural behavior, well compressive strength lightweight ternary binder foamed incorporating 20% - 25% 5% 10% ESP weight total binder, replacement. test results were analyzed compared with conventional without ESP. It was observed class C material. combined utilization increased control Furthermore, most cracks prisms nearer middle samples between two locations loads applied same load value at both locations. also air voids blocked activity development C-S-H gels thus increase strength. can be beneficial reducing overall cost. cost produce 1 m3 reduced ranging from 12.59% (with ESP) 17.53% ESP). concluded M4 mix optimum cost-effective, maximum replaced (35%), strengths significantly higher than M0.
