THE FACT THAT PUMICE has an amazingly versatile form factor has allowed the Hess Pumice company to take an impressive pumice deposit in southeast Idaho and bring to market a wide range of pumice-based products for industrial processes and consumer goods.
The DIRECTORY BELOW links the published expertise of the Hess family’s pumice beneficiation know-how—sixty-plus years mining, refining, functional application, performance research, and blended and cast product products.
- GENERALIZED INFORMATION
- Hess Pumice
- The primary Hess site covering the various uses/applications of pumice, physical and chemical characteristics of pumice from the Hess deposit, about Hess Pumice company, world-wide shipping, and PDF publications library—safety and technical data sheets, statements and certifications, and information publications (research summaries, whitepapers, and knowledge briefs).
- Hess Perlite
- Hess also operates a perlite ore mine and an accompanying production facility that expands, packages and ships expanded perlite grades—in bulk or packaged in supersacks, 4 cf. production bags, or 8-quart retail-ready bags (horticultural grade).
- The Pumice Store
- The vast majority of pumice is sold by the ton (bulk shipped) or by the pallet for industrial and product manufacturing processes. Hess created the online Pumice Store—and backed it with a dedicated fulfillment center—to make small quantities of pumice available in various grade sizes for various needs, including sampling. Shop by grade size or shop by application.
- About Pumice
- A broad-band look at pumice—its natural origins, historical uses, modern uses, and mining, refining, and packaging for market processes.
- Pumice vs. X
- There are a handful of pumice-like materials on the market, touting the same highly versatile, widely applicable foamed stone form factor. What is not pumice-like about them? Their man-made genesis and green-cred sustainability.
- APPLICATION SPECIFIC
- Hess Agrox
- Site focuses on the specific applications of pumice in the agricultural industries—crop and horticultural applications, livestock, and waste management (including water filtration and composting) as well as related soils-based industries like reclamation, landscaping, engineered soils.
- Hess NCS
- Micronized pumice grades—non-crystalline silica (NCS)—for use as functional fillers in paints, coatings, epoxies, caulks, rubber compounds. Amorphous silica grades range from 12 microns to 3 microns (average particle size).
- Hess Pozz
- Pumice: the original concrete pozzolan. Details the advantages of pumice pozzolan in terms of consistent performance, cured density, mature strength, ASR mitigation, color, green credibility.
- Pumice Concrete
- Site looks at the applications and benefits of pumice-enhanced concrete—pumice pozzolan (as a cement replacement + performance enhancer) and lightweight, insulative pumice aggregate.
- Lightweight Insulative Concrete
- Examines the role of both expanded perlite and foamed-stone pumice as an aggregate in lightweight, insulative concrete applications—mating thermal mass to thermal resistance.
- Replace Fly Ash with Pumice
- Extensive ASTM-standard research quantifies powdered pumice as a remarkable concrete pozzolan.
- ASR Mitigator
- Focuses on the research done by the University of Utah specifically into the ability of pumice pozzolan to flatline the alkali-silica reaction in the presence of reactive aggregates, including how it does so.
- Canoes of Concrete
- Sourcing lightweight competition aggregate for student engineering teams competing in the ASCE’s annual Concrete Canoe Competition.
- Microbead Replacement
- With US law banning the manufacture and commerce of products containing plastic microbeads (Microbead-Free Waters Act of 2015), pumice stands as a proven and effective replacement for microbeads in cosmetic and cleansing products while doing no harm the environment.
- BLENDED PRODUCTS
- US Grout
- An ultrafine cementitious injection grout supercharged with pumice pozzolan. US Grout Ultrafine™ was developed by the U.S. Department of Energy (Sandia Labs), is manufactured by Hess Pumice, and is distributed and supported by injection grouting experts Avanti International.
