CX-007014: Categorical Exclusion Determination

A Permeable Active Amendment Concrete (PAAC) for Contaminant Remediation and Erosion Control
CX(s) Applied: B3.6
Date: 09/09/2011
Location(s): Aiken, South Carolina
Office(s): Environmental Management, National Energy Technology Laboratory

The objective of this project is to develop a permeable active amendment concrete (PAAC) consisting of apatite, limestone, organoclays, zeolite, sand, and cement. The amendments will be incorporated in a concrete matrix by replacing a portion of the crushed stone or sand in traditional pervious concrete. PAAC has the potential to produce a barrier that combines high structural integrity with the ability to stabilize a variety of contaminants.
