Company Profile

Roman Pantheon

Compacted Ash and Lime

Resonant Shock Compaction, LLC (RSC LLC) has developed and licensed its patented and commercially proven Resonant Shock Compaction (RSC) technology to:

Manufacture high-valued construction blocks, panels and aggregate from mixes of coal ash, soil, recycled concrete, mining waste, other waste materials, and binders. The process uses about 5% to 10% cement or lime binders, which depends upon product design specifications. RSC compacted coal ash blocks contain 50% to 90% ash. Similarly the 2000 year old Roman Pantheon in the photo was built by compacting a mix of volcanic ash, crushed brick aggregate and lime.

Provide high capacity production, volume reduction, treatment and stabilization of contaminated soil for safe disposal.

Manufacture large refractories for the iron and steel industry.

RSC LLC, its partners, or licensee will design, build, or operate RSC manufacturing plants. The steps leading to the building of an RSC plant are:

Materials evaluation. (material quality, quantity, cost).

Make test blocks of various mixes with the goal of manufacturing strong, durable and stable products that meet structural design and economic goals.

Test the blocks using ASTM methods such as compressive strength, freeze-thaw durability and ultrasonic methods.

Develop a site specific technology licensing agreement.

Design, build and commission the new plant.

RSCL can quickly assess the viability of using a particular ash to manufacture construction products from coal ash or other waste materials. We have tested hundreds coal ashes, mining wastes and soils from the US, Japan, China, Korea, India, Canada and other countries. Coal ash types have included pulverized coal fired boiler Class C and Class F ashes with and without dry limestone and sodium (trona) injection flue gas scrubbers, bottom ash, mixed pond ash, stoker fired high carbon ash, and circulating fluidized bed ash contain high calcium from limestone flue gas scrubbing. In all cases the test blocks were strong enough for building walls.

A full scale commercial sized RSC machine is installed at The University of Denver, Department of Physics, Environmental Materials Laboratory. RSCL and the University cooperatively conduct contract research, materials testing and technology development.
