In this paper, a study was conducted to improve self-healing and strength properties using sodium acetate. The developed inorganic-organic self-healing materials and recycled sodium acetate were manufactured to evaluate self-healing and permeability reduction properties. As a result of the experiment with recycled sodium acetate, the compressive strength of the material prepared with anhydrous and trihydrate at a ratio of 7:4 was higher than that of the mixture using anhydrous. It was confirmed that the compressive strength was improved by 3~7 %. In addition, the maximum permeability reduction rate was 92.6 %, which satisfied the self-healing properties.
