JUNO XP surpasses major milestone in Stage 4 testing toward achieving 1709 ASTM certification

By | Concrete | No Comments

JUNO XP - alternative supplemental cementious material

For years, contractors have utilized several common types of supplemental cementitious materials (SCM), including fly ash, slag cement, calcined clays, and silica fume to partially replace traditional Portland cement in concrete mixes. The use of these materials has been supported by significant research and testing, as well as long-term performance monitoring.

Now the same rigorous testing procedures are being applied to JUNO XP, Surface Tech’s alternative supplemental cementious material (ASCM), and the reports from Stage 4 testing show JUNO XP produced “fantastic results,” according to Jon Belkowitz, PhD, chief technology officer for cement.

“The 90-day strength test results show JUNO XP is awesome! Throughout the 90-day set of results, the strength and durability of the JUNO XP-enhanced concrete proved out above the 1709 ASTM references.”

The innovative technology behind JUNO XP generates a hardened matrix that increases cementitious efficiency (see Compress Strength graph), and the resistance to physical attack (see Underwater abrasion graph).

Testing on JUNO XP covers a one-year time period, and by achieving excellent results at the 90-day milestone, the product will now enter the field-testing phase.

By | Case Study - Concrete, Concrete | No Comments

JUNO XP alternative supplemental cementitious material (ASCM)For challenging winter weather, look no further than Colorado. During the cold months, concrete pavement must withstand an unending cycle of freeze-thaw and a constant barrage of de-icing salts. When a Colorado-based concrete provider  sought a new solution to this age-old problem, they turned to Surface Tech.

JUNO XP ConcreteWith fly ash in short supply, the concrete provider needed an alternative supplemental cementitious material (ASCM) that would meet ASTM C 672 specifications for a high-end residential driveway. The specs called for a high compressive strength and an ASCM that would ensure a dense hydrated concrete matrix. It was an ideal test for JUNO XP, Surface Tech’s pioneering ASCM product.

Using Surface Tech’s Rapid Deployment technology, JUNO XP was easily added to the mix with no issues or delays in the standard process. Concrete finishers remarked on the ease of finishing despite the reduction in paste content. The mix also retained fresh properties, compressive strength and resiliency when tested from samples fabricated during laboratory and field trials. Best of all, the test delivered significant cost savings without sacrificing fresh or hardened properties. Moreover, a third party testing laboratory confirmed that the JUNO XP concrete maintained the strength and shrinkage required by the engineering specifications.

The concrete provider in Colorado — and others like it across North America — have consistently found that JUNO XP-enhanced concrete will maintain performance, lead to cost savings and create an environment for a greener concrete mix design.

Chief Technical Officer Jon Belkowitz, PhD to present at Concrete Expo in 2019

Jon Belkowitz, PhDSurface Tech’s Chief Technical Officer Jon Belkowitz, PhD, will present an overview of Alternative Supplementary Cementitious Materials (ASCM) at Concrete Expo on Jan. 31, 2019 in South Bend, IN. He will provide an overview of ASCM, including how these materials manipulate the microstructure of concrete. Belkowitz has conducted extensive research into ASCM, and part of his presentation will review ongoing concrete research projects.

Interest in ASCM has grown in recent years as supplies of fly ash have decreased. Many producers have also begun to seek out alternatives to these materials in a quest to improve mix workability and hardening properties. Add to these motivations an overall growing concern for the environmental impacts of traditional cement production, and you begin to see why producers are looking for reliable alternative cementitious materials.

At his presentation, you will learn how ASCM-enhanced concrete performs in both workability and hardening stages, as well as the means and methods of employing these products in concrete manufacturing. His presentation will also detail how ASCM can produce civil infrastructure that is both stronger and last longer.

ACE XP aramid polymer fiber additiveAll require strength, flexibility and abrasion tolerance to achieve high performance. The common ingredient that delivers those winning traits is aramid fibers. These polymer synthetic fibers provide advantages that make them ideal for a wide range of products. So it’s not surprising that more than 60,000 tons of aramid fibers are produced annually, and demand continues to grow as new applications emerge.

Years ago, Surface Tech recognized the superior advantages that aramid fibers, particularly para-aramid fibers, could provide to asphalt applications. The company began offering the ACE XP aramid polymer fiber additive after years of painstaking research and multi-geographical testing. Back then, the challenge was to find a way to harness millions of tiny fibers into a final product that could be easily managed. By combining para-aramid with a wax treatment, Surface Tech achieved its goal of creating an additive that successfully reinforces and properly doses the entire matrix of asphalt.

The wax binds the polymer fibers to allow for an easy, reliable method for feeding into the asphalt mix. Once added, the wax melts and is fully soluble within the mix to release the polymer fibers in a uniform distribution. This unique delivery process produces the highest performing blend of Fiber Reinforced Asphalt Concrete (FRAC) on the market, and any asphalt project can benefit from ACE XP.

If you want an asphalt surface that resists cracking and rutting and dramatically extends the life of your pavement, call us. With para-aramid fibers, you’ll get asphalt that’s stronger than steel, and only from ACE XP — the Number One choice for strength, flexibility and abrasion tolerance.

JUNO XP acts as an alternative supplementary cementitious material (ASCM) that reduces the need for traditional cement. Because JUNO XP is a powder, it can be easily incorporated into any conventional dispersion system — silo, hopper, supersacks, bags and dissolvable bags. Integration ease is what separates JUNO XP from other new technologies.

It can also save you money. Contractors can expect to see a reduction of 20 to 35 percent of the cost of conventional cement by adding JUNO XP to the mix. Savings and ease of use alone make JUNO XP a preferred alternative supplementary cementitous product.

Yet JUNO XP goes further by providing key environmental benefits. Since traditional cement production accounts for 88% of the emissions associated with the average concrete mix, JUNO XP provides a way to offset this pollution and provides a means to achieve LEED credits and an improved carbon footprint for your project. Reduction of cement in mix designs is a calculable formula recognized by ACI/ASTM for credits.

Best of all, the ease of use—plus the dollar and environmental savings—come with no sacrifice in performance. The proprietary and novel properties of JUNO XP change cement hydration at the molecular level to increase the strength (tensile and compressive) and the durability of concrete. And it improves the performance of concrete on other levels, including workability and shrinkage control.

JUNO XP has passed Stage 1 and 2 testing to achieve ASTM C1709 certification with impressive results, with final Stage 3 testing on the near horizon. Key early adopters are lab and field testing and piloting the product in various mix designs throughout the U.S. and Canada and report stellar results.

ACE XP Polymer Fiber for asphalt

Contractors have come to depend on ACE XP Polymer Fiber from Surface Tech to make asphalt more durable and long-lasting. How does this high-tech additive deliver on its promise to produce extreme performance asphalt? The key lies in its chemical makeup — it’s composed of aramid polymers.

Aramid polymers contain a set of chemical properties that give them outstanding strength, flexibility and abrasion tolerance. They’re particularly useful in applications where flexing tolerance is important, like armor, airplane wings, ropes, cables, undersea pipelines, and of course asphalt applications.

To create ACE XP, high-strength aramid fibers are bundled and coated with wax to produce an asphalt additive that is simple and dependable to mix with any WMA or HMA in both drum and batch operations.  In fact, this binder use insures proper aramid delivery into the WMA/HMA; and coupled with our precise dosing equipment, delivers consistently intended amounts into every ton of asphalt.

One of the most outstanding performance benefits of ACE XP lies in its micro roots. These tendrils tenaciously anchor themselves into the bitumen of the asphalt, providing 400,000 psi tensile strength. The result is a three-dimensional reinforcement throughout the asphalt and a flexibility that resists rutting during hot summers and cracking through cold winters.

Contractors will also appreciate the fact that ACE XP is a “dry” polymer fiber. Comparatively, it’s less expensive, more reliable, and easier to adopt. The MD3+ dosing system from Surface Tech delivers an easy, foolproof way to add ACE XP to any asphalt mixture.

Yet the ultimate beauty to ACE XP is its scalability and batch-to-batch reliability. Combined with the life-span improvements it provides, it’s a winning way to armor your asphalt for the long haul. That kind of reliability allows contractors to sell and place with confidence, knowing the asphalt they provide will deliver extreme performance based on an excellent polymer.

UC Berkeley and University of Alberta put it to the test

ACE XP Polymer FiberSurface Tech’s ACE XP Polymer Fiber (advanced performance product) is currently undergoing rigorous testing by researchers at two stellar universities. The quest:  Fully understand and document the benefits and material advantages of adding ACE XP Polymer Fibers to asphalt mixtures.

Principle investigators (PI’s) at the University of California at Berkeley including Dr. Angel Mateos in the university’s Pavement Research Center (UCPRC), are testing ACE for strength, fatigue and modulus in compliance with CALME standards; all in conjunction with Teichert Materials, ST’s NoCal distribution partner.  UCPRC is using the new Ideal CT test as part of their regiment.

“There has been an explosion of interest in the ACE XP Polymer Fiber product within our industry,” says Phil Blankenship, P.E., a strategic advisor to Surface Tech. “Major universities are taking notice. This type of high-level performance testing will help producers everywhere better understand ACE XP and how it can improve their asphalt mixes.”

When word of ACE XP Polymer Fiber reached the University of Alberta in Canada, Luis Perca (graduate student) and Leila Hashemian (Asst Professor), a faculty member in the Chemical & Materials Engineering Department, contacted Surface Tech to request assistance in analyzing the product. PI’s there are now testing ACE XP with a specific focus on performance in the tough Canadian climate, while also analyzing how the individual fibers contribute to asphalt strength, workability and long life.

“We expect results from the testing and analysis conducted by these universities will be available in six to nine months, and we’re pleased to see the continued interest among academics in our product,” says Blankenship.
