The effect of reduced iron powder on the performance of functional mortar was studied. Aimed at the construction performance, the experiments of consistency and water retention were carried out. Aimed at the mechanical properties, tensile bond strength, compressive strength and flexural strength experiment were carried out. The results show that the content of powder has little effect on mortar consistency. It can improve water retention. The 14d tensile bond strength is 36.2% higher than the reference mortar, which can meet the requirements of plaster-mortar. The compressive strength of 7d mortar was 24.2% higher than that of reference mortar. Compared with the reference mortar, the 28d compressive strength increased 13.6%, the 7d flexural strength increased 36.6%, and the 28d increased 25.8%.
