This proposal is to address the feasibility of water-reactive grouts as a "smart" material capable of being placed during construction but not activated until a threat event occurs which degrades the original watertight integrity. When such degradation occurs, it will expose the water-reactive grout to groundwater. This will trigger the hardening process which will automatically affect a seal at the location of the groundwater intrusion.
Anticipated Results:The anticipated results of Phase I is documentation of the current state of knowledge of water-reactive grouts, a laboratory testing plan to complete documentation of properties, and a software development plan for simulation of in situ performance. Phase II would execute the laboratory testing plan and software development, sufficient for commitment to the concept of water-reactive grouts as a "smart" material for both NRC and conventional purposes.
