In this paper, the foaming properties of a foaming agent were studied. The foaming agent was prepared with rosin as the basic material. The effects of alkali addition, reaction temperature and reaction time on the foaming properties of foaming agent were studied. By adding sodium dodecyl benzene sulfonate and gelatine, the performance of the foaming agent was improved. The foaming ratio and bleeding rate were investigated. The foamed concrete was prepared using the high-efficiency foaming agent. When water to cement ratio (w/c) is 0.42–0.46, the dry density and compressive strength are 400–500 kg·mE−3 and 1.25–1.5 MPa, respectively.
