6.2 CERAMICRETE: AN ALTERNATIVE RADIOACTIVE

WASTE FORM

Arun Wagh

6.2.1 I NTRODUCTION

Cement is a familiar material widely used in the construction industry and has been
successful in stabilizing many wastes. 1 Conventional cement systems may only
accommodate a low loading of the waste, resulting in large volume increases and
high transportation and disposal costs. In addition, cement interacts with and is not
always compatible with the waste, for example, acids. Ceramicrete is a rapid-setting
phosphate grout system that comes close to producing ceramics by chemical bonding
at room temperature and exhibits advantages of both vitrification and cement grout
without their major drawbacks. Ceramicrete technology is based on a form of
chemically bonded phosphate ceramic conceived and developed at Argonne National
Laboratory (ANL) and holds promise as an alternative to vitrification and cement
