Resonant Shock Compaction Solidifies Coal Ash
Resonant Shock Compaction, LLC (RSCL), has a new way to solidify coal ash and other waste into high value building materials. The patented process has already been in commercial use for over 10 years, producing special large refractory components from a variety of materials.
Basically, the material is placed between two "shake" tables, and resonant vibrations are applied, setting up a shock wave. The material flows and intermixes to become very uniform and very hard, compacted by 40-60%. The resulting block or panel contains 80-90% ash material, and is impermeable, nonleaching, and has very high strength, meeting ASTM standards for many construction applications. It also can be sawed and nailed.
The process features low capital costs, high process throughput, and large size shapes, suitable for many types of building products, and enabling new more economical building practices.
Besides turning coal ash into building products, the technology can also immobilize radioactive and hazardous material. A remediation service based on RSC is under discussion.
The technology has also been tested in combination with Argonne's Ceramicrete binder (see UFTO Note October 23, 1997), and substantially enhances the performance of that process.
The company will grant site licenses, and is seeking equity investment for working capital and to support business development. Discussions and negotiations are already underway with a number of utilities. A revised business plan will be ready shortly, and technical and economic information is available from the company.
