Beat the fly ash shortage with JUNO XP!

By | Concrete | No Comments

Beat the fly ash shortage with JUNOConcrete producers often rely on ASTM C 618 Class F fly ash, derived from burning coal in power plants, as a partial substitute for Portland cement. Yet despite loosening regulations, the coal industry continues to suffer from America’s dwindling appetite for coal, and the unintended consequence is a shortage of coal combustion residue and fly ash. Many concrete producers now report having to use straight cement mixes, which increases cost.

Globally, significant sources of Class C fly ash exist, but the lower quality makes this product difficult to activate, and transportation adds to the cost. Class C fly ash is not as effective in mitigating chemical attack as Class F fly ash. However, there is one sure way to beat the shortage of high-quality fly ash:  Switch to Juno.

Juno XP is an advanced mineral admixture developed by Surface Tech that can replace fly ash as a partial substitute for traditional cement. It can be used in standard concretes, as well as in specialty applications without sacrificing performance.

The core technology found in Surface Tech’s Juno XP is a revolutionary building material using cutting-edge advancements in mineralogy combined with a graduated fiber matrix to reduce material cost. In fact, concretes that incorporate Juno as a binder often have higher performance characteristics than traditional concretes.

For more information on how Juno XP can lower cost and improve performance in projects like soil stabilization, controlled density fill (CDF) and rip-rap, visit http://surface-tech.com/portfolio/juno/.

JUNO passes initial laboratory testing with flying colors

Juno ConcreteThe results are in, and JUNO has proven it can increase strength and durability as well as decrease shrinkage in the laboratory tests that have been conducted to date. Surface Tech CTO Jon Belkowitz reports the product performs well in all areas that have been evaluated.  He sees JUNO as an easily-adoptable means to improve most types of concrete mix designs. The evaluation of JUNO will continue as it completes ASTM C1709 certification.

“Overall improved performance characteristics are some of the value propositions Juno is creating”, says Dr. Belkowitz, who also serves as the Director of Research and Development at Intelligent Concrete, a materials laboratory that specializes in concrete research, development and education with a focus on innovation.

It’s the fine particle size, in particular, that plays an important role in the material properties of JUNO. The core technology found in JUNO employs a revolutionary building material that utilizes cutting-edge advancements in mineralogy, combined with a graduated matrix.

The result is an alternative supplementary cementitious material that can reduce the amount of traditional cement and fly ash needed in concrete, while increasing fresh and hardened properties, thus saving money on cement/fly ash in the concrete mix. And Juno reduces CO2 emissions resulting from cement usage.

Better yet, and in concert with the performance characteristic improvements, JUNO produces a concrete that maintains fresh properties and improves strength in the final product, which adds up to a longer life for the concrete.

“We’ve run a number of tests for different applications, and JUNO is proving to be a phenomenal product,” says Dr. Belkowitz.
