Title: Bendable Concrete: Revolutionizing Resilient Urban Infrastructure

Abstract: To address the challenges of rapidly growing worldwide urbanization, this talk delves into the advancements in concrete technology. Globally, the concrete industry produces an estimated 12 billion tons annually, averaging about 2 tons per person, making it the second most consumed material by mass after water. However, conventional concrete's brittleness poses safety and durability concerns, especially when subjected to tension-induced cracks. These cracks allow water and other aggressive chemicals to permeate, leading to the corrosion of embedded steel reinforcements.

In response to these challenges, an innovative cementitious composite known as "bendable concrete" has developed. This ultra-ductile material offers tensile ductility over 300 times greater than regular concrete. While retaining similar appearance and mechanical properties as conventional concrete, bendable concrete exhibits unique ductile behavior, producing cracks finer than human hair (
