Concrete in architecture: Redefining form, space, function, and insights from bibliometric analysis
Abstract Concrete has become a cornerstone in architectural and engineering innovation, as it seamlessly integrates structural performance with artistic expression. Its evolution from ancient opus caementicium to contemporary ultra‐high‐performance concrete illustrates its adaptability to the change in technological, environmental, and design paradigms.

Abstract This study investigates the impact of magnetic alignment of micro steel fibers (0.35%, 0.70%, and 1.05% contents) on the mechanical and electrical properties of fiber‐reinforced self‐compacting concrete. A simplified magnetic circuit was designed and built to align the fibers within the concrete matrix.
