  Flexible concrete, also known as bendable concrete, achieves ductility — a stark contrast to the brittle nature of conventional concrete. This fundamental difference allows flexible concrete to be more versatile in application, offering improved performance, durability, and higher strength. Several key characteristics highlight the distinction between flexible concrete and traditional concrete. Conventional concrete is inherently brittle, whereas flexible concrete is designed to be more ductile and bendable. Additionally, flexible concrete typically offers greater durability and strength. Another notable difference lies in the composition. Conventional concrete uses less cement, which limits its ability to recover from cracks. In contrast, flexible concrete possesses a self-healing capability, as it can repair minor cracks through a natural reaction between carbon dioxide and water, enhancing its longevity and structural integrity.
