- The 4SIGHT computer program has been designed to facilitate performance assessment of underground concrete structures.
- 4SIGHT uses a continuum scale transport/reaction model to prediction the dissolution and/or precipitaton of minerals and salts.
- This web application is a graphical front-end to the original command line program. A description of the assumptions, the algorithms, the validation, and the meaning of input variables are discussed in a report published by NIST. Click on NIST-IR 6747 to download the 750 kB PDF document.
