Like many of our innovations, new technologies were developed to solve complex issues in our industry. With increasing demand for high-quality fly ash, SEFA recently developed a new forecast model to evaluate the estimated future demand for material, and make ash marketing more predictable and efficient. SERVICE The foundation of our Company is the willingness to serve. For over 40 years, SEFA has focused on providing a reliable supply of quality fly ash for the ready mix concrete industry. Throughout our history, we have also customized and added services that our utility or construction customers needed at the time. SEFA continues its strong heritage of integrity, excellence, safety, and unsurpassed service to its customers. ENVIRONMENTAL FOCUS SEFA is a technical service and solution provider principally engaged in processing and marketing environmentally sustainable products derived from fly ash for the concrete industry. SEFA has recycled over 20 million tons of fly ash in the last 30 years, and the company is an integral part of some of the country’s most successful coal ash recycling programs. Our biggest impact is cleaning up coal ash from ponds and removing it from the environment permanently. STAR® REFINED POZZOLAN Thermally Beneficiated Class F Fly Ash STAR® Refined Pozzolan has applications ranging from ready-mix concrete to paving to precast products. It also promotes sustainable development by cutting down on the amount of new materials used in manufacturing. It’s recognized by the U.S. Green Building Council as a post-industrial, pre-consumer recycled material, which means it can contribute toward LEED credits. Those aren’t the only advantages of STAR® Refined Pozzolan. Its superior strength and air entraining characteristics allow its use in more concrete mixes and at higher dosage rates. It also improves workability and reduces permeability, which delays the onset of reinforcing steel corrosion. STAR® Refined Pozzolan allows manufacturers to confidently tailor mixes precisely to meet weather, job, or specification requirements. MORE SUSTAINABLE INFRASTRUCTURE Improved Strength, Durability, and Affordability of concrete projects is achieved with higher replacement ratios of STAR® Ash for Portland cement: The improved pumping capability of high ash concrete mixes means that material can be pumped higher and further, which reduces construction costs and results in higher quality end products. With higher ash usage ratios, the permeability of concrete is reduced which gives concrete structures protection against freeze/thaw deterioration and the penetration of chemicals and salts into the structures that cause corrosion and premature failure. These positive factors combine to offer engineers, architects, and owners a superior end product at a lower cost by using maximum ratios of consistently high-quality STAR® Ash. About For over 40 years, The SEFA Group has been making a positive difference by transforming coal combustion residuals into environmentally sustainable products for the concrete industry. Our patented STAR® Technology makes us the country’s leader in thermal beneficiation of fly ash.
