This study investigated the properties of foamed concrete by using surfactant foaming agent and synthetic foaming agent. The effects of foaming agent types on the compressive strength, density and pore structure of the concrete were investigated. The samples were assessed by XRD analysis and simultaneous SEM was used to study their pore distribution. This study showed the improvement of important properties of foamed concrete. Lower pore distribution and correspondingly higher compressive strength values were reached. Also, synthetic foaming agent had more positive effect on the strength of foamed concrete.
