[V-372] Evaluation of stability for self healing concrete with recycled materials
Keywords:RECYCLED MATERIALS, SELF HEALING CONCRETE, STABILITY, ETTRINGITE
In this study, the concrete to which composite recycled materials was added self-healing concrete. The water flow rate was determined for estimation of self healing. It was confirmed that self healing occurred by decresing the water flow rate. X-ray diffication and SEM observation were performed to identify ettringite. Needle-like crystals of ettringite were confirmed with increased the addition rate of composite recycled materials. The reason for the decrease in water flow rate was considered to be a change due to ettringite at the cracked part.
