The Manga Guide to Concrete

This manga is about the wonderful building material concrete and installations made of it. The Romans were the first to use concrete to build roads, bridges, harbors, temples, squares, and water systems, many of which still survive today. Together with the Kenji, an architecture student, and the Sibyl, you'll find out how Roman concrete was different from modern concrete, walk across the Hijiri-Bashi Bridge, and visit the Hukagawa Cement Factory.
