The SEFA Group About SEFA Services Innovation Safety Sustainability Contact FLY ASH SALES STAR® REFINED POZZOLAN CLASS F FLY ASH STAR ® Refined Pozzolan is a high-quality, consistent, Thermally Beneficiated Class F fly ash. It has applications ranging from ready-mix concrete to paving to precast products. Not only does STAR Refined Pozzolan exceed all the requirements for the most stringent specifications for fly ash used as a supplementary cementitious material, it also has superior air-entraining characteristics. Concrete producers can use the same dosage rate of air-entraining admixture in all of their concrete mixes – regardless of the amount of STAR Refined Pozzolan used in the mix design. These “transparent” air-entraining characteristics lower the concrete producer’s cost for quality control and reduce the amount of concrete rejected at the job site. It also promotes sustainable development by cutting down on a number of new materials used in manufacturing and is recognized by the U.S. Green Building Council as a post-industrial, pre-consumer recycled material, which means it can contribute toward LEED credits. In addition to its superior strength and air entraining characteristics, 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.

Yes. STAR® Refined Pozzolan is a 100% post-industrial recycled material from the combustion of coal to produce electricity. Using STAR® Refined Pozzolan as a mineral admixture in concrete reduces the demand to manufacture Portland cement and other virgin materials. We also convert 100% of the fly ash that would otherwise have been sent to a disposal site into a useful product. Will STAR® Refined Pozzolan affect my concrete mix design? Absolutely. The superior strength and air entraining characteristics of STAR® Refined Pozzolan will motivate you to use STAR® Refined Pozzolan in more concrete mixes and at higher dosage rates. ACI certified SEFA sales representatives can help you with mix testing and strength curves to optimize your savings through lower mix costs. Is STAR® Refined Pozzolan compatible with chemical admixtures in concrete? The only sure way to know how any admixtures, chemical or mineral, behave together is to test them. This we do know: the depleted-carbon STAR® Refined Pozzolan will have virtually no effect on the ability of your air-entraining agent to build and maintain an air void system in the concrete. Independent testing shows that concrete made with STAR® Refined Pozzolan has essentially the same air dosage rate as plain Portland mixes. Does STAR® Refined Pozzolan help with green building and sustainable construction? Definitely. By building a consistent air void system in concrete, owners know they are getting top performance in freeze-thaw conditions. Reactive fly ash also reduces permeability which delays the onset of reinforcing steel corrosion. Class F fly ash like STAR® Refined Pozzolan is one of the best strategies to defend against deterioration due to Alkali-Silica Reactivity and due to sulfates in the ground or water. When you use STAR® Refined Pozzolan, you produce durable, long-lasting concrete. Can STAR® Refined Pozzolan contribute toward LEED® Credits? Yes. Fly ash like STAR® Refined Pozzolan has been recognized by the U.S. Green Building Council as a post-industrial, pre-consumer recycled material. In addition, all of our raw material comes from local, American power stations, so it is almost always a local/regional material. Finally, LEED® credit can be granted for strategies that reduce the release of carbon dioxide by reducing the demand for Portland cement. SEFA representatives are available to assist you in calculating and preparing your LEED project submittals. Will STAR® Refined Pozzolan perform in conjunction with Slag? Yes. Blends of mineral admixtures such as STAR® Refined Pozzolan and slag cement can produce outstanding concrete properties such as low heat of hydration, superior ASR resistance, low permeability, reduced Portland cement consumption, and reduce mix cost. The superior air entraining and strength gaining properties of STAR® Refined Pozzolan allow you to confidently tailor your mixes precisely to meet weather, job, or specification requirements. How will STAR® Refined Pozzolan improve my concrete performance? STAR® Refined Pozzolan will improve the overall quality and performance of concrete by contributing to higher strength compared with ordinary fly ash, improved air entraining characteristics, consistently light color, and superior workability and finishability. STAR® Refined Pozzolan is a manufactured product that surpasses the quality and consistency of other processed material and by-product fly ash. How can I find out more about STAR® Refined Pozzolan? The SEFA Group has experienced, certified concrete Technical Sales Representatives across the Eastern United States who are equipped to demonstrate how Refined Pozzolan can improve the overall quality and performance of your concrete.

This beneficial use meets all environmental agency requirements for coal ash usage. STAR® Technology is a stand-alone solution that is cost-effective and eliminates long-term liability. PERMANENT SOLUTION Once transformed into a concrete matrix, any contaminants in coal ash are locked up forever. The elimination of ash storage facilities means the elimination of the need for long-term monitoring of wells and structures to detect and prevent ground water pollution. SUSTAINABLE The STAR® Technology solution to coal ash pond closure is an environmentally sustainable option that offers decades of multiple benefits. Reclaiming coal ash from ponds, and processing it into high-quality, consistent material allows it to be recycled for beneficial use in concrete. 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.
