Summary:Abstract In this paper, the method of producing bubbles by the reaction of aluminum powder and sodium hydroxide is used to make foam concrete test blocks and test their expansion rate and compressive strength. The foamed concrete was made through experiments of controlling the amount of cement, water and the relative content of aluminum powder, and the best mix ratio was selected from the comparative analysis of the compressive strength of 7d, 14d and 28dconcrete. Experimental results: The amount of cement and the water-cement ratio and the relative content of aluminum powder have a significant impact on the compressive strength and expansion rate. Conclusion: Starting from the ratio of the relative content of aluminum powder in foamed concrete to the amount of cement, the analysis of compressive strength and expansion rate provides a theoretical basis for the future study of its mix ratio, which greatly shortens the test time and saves costs.
