Searching for an easy way to reduce traditional cement in your concrete mixes? Look to JUNO XP

By | Concrete | No Comments

JUNO XP - alternative supplementary cementitous product

Lower cost. Environmentally friendly. Higher performance.

These are just a few of the benefits JUNO XP can deliver. But most contractors also want a replacement product that’s easy to adopt, and equally important, produces a concrete that performs well and can withstand the test of time. On all fronts, JUNO XP delivers.

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.

Turn to ACE XP for Extreme Performance Asphalt

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.

ACE continues to go academic

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.
