DEVELOPMENT OF SELF-HEALING SUSTAINABLE CONCRETE USING RECYCLED MATERIALS
Concrete is an open composite system, which allows the incorporation of various cementitious or inert materials as cement or aggregate components, thereby offering the possibility of creating a smart concrete. This study investigated the autogenous healing of concrete blended with ground granulated …
