Using the Advanced Light Source at Lawrence Berkeley National Laboratory, engineers and geologists examined the fine-scale structure of Roman concrete. The findings showed for the first time how the extraordinarily stable compound—calcium-aluminum-silicate-hydrate (C-A-S-H)—binds the material used to build some of the most enduring structures in Western civilization.
The discovery could help improve the durability of modern concrete, which within 50 years often shows signs of degradation, particularly in ocean environments.
