Ceramicrete: Applications, Advantages, and Economics
Applications
- Extremely fire-resistant spray-in insulation
- Oil well cements and seals
- Construction materials
- High-compressive-strength structural materials
- Sealants and coatings
- Encapsulation of a wide range of wastes (hazardous, radioactive, and nonhazardous)
- Impervious layer/jacket around contaminated materials
- Safe non-leachable storage of hazardous, mixed and radioactive materials (wet or dry)
- Encapsulation of nonhazardous wastes for beneficial uses such as fireproof insulation
- Construction materials such as bricks, blocks, roofing, tiles and road patch
- Structural materials requiring high compressive strength sealants and coatings
Advantages
- Sets in cold weather
- Room-temperature process requires no energy
- Fast reaction to form hard, dense ceramic
- Demonstrated up to 55 gallon scale
- Controlled cure rate for optimized process and properties
- Incorporates large quantities of waste materials, both solids and liquids
- The mixed binder is pure white; Ceramicrete cement can be produced in any color
- Working times vary from 20 minutes to 5 hours
- Ceramicrete sets with strengths comparable to ultra-high-strength concrete
- Ceramicrete expands slightly when it sets, and forms an excellent seal, while conventional cements contract
- The set material has a nonporous finish
- Ceramicrete can bond to itself or other materials, including conventional cements
- Ceramicrete does not bond to plastics or resins and can easily be extracted from a mold
Economics
- Specialty applications favored to take advantage of excellent physical properties, including low porosity, nonflammability, and strength
- Manufacturing equipment common to concrete mixing and handling is sufficient
- Beneficial use of common waste materials extends value (e.g., ash, plastic, sawdust, slag)
- No formation energy required, in contrast to fired ceramics or vitrification
