A new and exciting photographic process in concrete has been receiving rave reviews and stands to be one of the most profound effects this century in architecture and concrete construction. The process that takes a photograph and reproduces it in concrete, is about to be used at the Smithsonian Museum.
Another proposed use is the re-creation of a civil war photograph in a 28' wall as the entrance to a civil war park in Mississippi.
The permanent photographic image in the concrete is made using a process that alters the cement matrix exposing the aggregate in the mix.
