In order to explore the factors affecting the strength of lightweight and high-strength foamed cement, ordinary Portland cement is used as the cementing material, and the target dry density is 400~410kg/m3 by controlling the content of foaming agent and foam stabilizer. Lightweight high-strength foamed cement specimen with strength of 4.4MPa. Controlling a single variable, the compressive strength and microscopic morphology changes of foamed cement specimens with different self-made reinforcing agent content and fly ash content were studied. The research results show that when the fly ash content is 20%, the strength of the sample without reinforcing agent reaches the best 2.4MPa; when 2wt% of the reinforcing agent is added, the strength of the sample reaches the maximum compressive strength of 4.4MPa, an increase of 83 %. Scanning electron microscope microscopic morphological observation results show that after adding the reinforcing agent, the foamed cement cell is more uniform, the cell wall becomes denser, and the cell defects are reduced, which explains the macroscopic advantages of lightweight and high-strength foamed cement.
