Abstract

Portland cement concrete faces challenges related to durability, strength, and repair costs, and it also contributes to CO₂ emissions. Although sodium silicate and biopolymeric microcapsules have already been reported in the literature, this study focuses on the autonomous self-healing of the cement...
