AN INORGANIC SELF-HEALING BINDER CAPABLE OF PROMOTING THE FORMATION OF NEEDLE-LIKE SELF HEALING MATERIAL AND SELF-HEALING CONCRETE USING THE SAME

摘要

The present invention relates to an inorganic self-healing binder for promoting the formation of acicular self-healing materials and self-healing concrete using the same. The present invention can provide self-healing concrete with improved self-healing properties by containing an inorganic self-healing binder in which Portland cement (OPC) is mixed with an inorganic mineral of blast furnace slag powder and a crystal accelerator, thereby inducing the formation of acicular hydrates in the cracks, wherein the acicular hydrates are generated across the cracks to effectively heal the cracks, and by producing plate-shaped hydrates and amorphous products around the acicular hydrates to improve the self-healing properties.
