JUNO XP — an “insurance policy” for Ultra-High Performance Concrete

By | Concrete | No Comments

Ultra-High Performance Concrete (UHPC) as defined by the American Concrete Institute (ACI) Concrete Terminology and ACI 239 stipulate calls for meeting a compressive strength between 17,000 psi up to 22,000 psi with specified durability, toughness and tensile requirements provided by the inclusion of fibers. However, because of it’s the materials employed high strength, UHPC can be difficult to create and can become brittle and prone to cracking.

Fortunately, recent UHPC testing and real-world applications by Surface Tech are demonstrating that JUNO XP, the company’s proprietary alternative supplementary cementitious material (ASCM), can provide an “insurance policy” against UHPC brittleness and sub-sequent cracking.

“UHPC has so much cement in it you have to go with a low water mix, and that’s where you run into the possibility of cracking at both early and later stages of the concrete,” said Jon Belkowitz, PhD, Surface Tech’s chief technology officer.

JUNO XP has a mechanical impact on fresh concrete that allows for a reduction of cementitious material, while still maintaining the cream needed to allow grey concrete to flow easily into the formwork. Moreover, JUNO XP has also proven it can increase strength and durability.

“It makes UHPC stronger, tougher and last longer at no additional cost,” said Belkowitz, who added the product is showing spectacular results in current UHPC application testing by one of the nation’s premier concrete precasters.

“JUNO XP is decreasing the binder content by 15 to 25 percent without sacrificing fresh or hardened properties.”

Those who specify and work with UPHC should welcome these results and the fact that JUNO XP is easily adoptable and improves standard, higher performance concrete mixes, in addition to UHPC.

“JUNO XP can be considered a ‘toughening agent’ for UHPC,” said Belkowitz, “meaning it can increase the strain on the concrete before failure, or increase the energy under stress. This positively affects the strain curve as opposed to other supplementary materials, which tends to make the concrete more brittle at high strengths.”

As numerous tests and real-world applications continue to demonstrate that JUNO XP delivers a revolutionary advancement in concrete solutions, it leads Belkowitz to issue his best advice:  “Start using Juno XP today! It’s flipping awesome!”

ASCM — an acronym for the future of concrete

JUNO XP

Acronyms. They’re everywhere. Each industry has plenty, and even our text language is well populated with LOL, OMG and a long list of others. So you may groan a bit when you see a new one, but ASCM for the concrete industry is one you’ll definitely want to know and remember.

Alternative supplementary cementitious materials (ASCM) are making waves within the industry, and for good reasons. One, they can partially replace traditional cement in a wide range of concrete mixes. This is good news for the environment, because the production of traditional cement requires enormous amounts of energy and releases CO2 into the air.

JUNO XPTwo, ASCMs have the capability to deliver important improvements to concrete mixtures. They can increase strength and lifespan, improve workability in placement and require less water, while still delivering the creaminess required for most concrete mixes.

Third, to the delight of many, ASCMs can reduce the cost of concrete. And when you combine the cost savings benefit with added strength that provides improved resistance to abrasion, salts and acidic environments, it’s no wonder attention to ASCMs has grown over the past few years.

ASCMS such as silica and fly ash have been around for a while. But these materials do not address all of the shortcomings of Portland cement in certain applications and environments.

That’s why Surface Tech developed JUNO XP, an advanced mineral admixture that can partially substitute traditional cement. It can be used in standard concretes and 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 and nanotechnology combined with a graduated fiber matrix to reduce material cost.

Best of all, adding JUNO XP to your mix is easy. You can add it at any point in the production process—at the plant, on the job site, or wherever it fits your need.

So now that you know about ACSM, all you really need to remember is JUNO XP.

Innovative products that deliver better, stronger, longer-lasting building materials 

Transportation Research Board (TRB) 98th Annual MeetingIt’s almost here! The Transportation Research Board (TRB) 98th Annual Meeting will convene next week in Washington, DC.  We’ll be there, and we invite everyone to drop by our booth to learn how Surface Tech products can deliver significant benefits to your next concrete or asphalt project.

Our innovative ACE XP polymer fiber solution can make asphalt stronger than steel. JUNO XP, our alternative supplementary cementitious material (ASCM), utilizes cutting-edge advancements in mineralogy and pozzolans to improve the performance of concrete at a microscopic level. Stop by and learn more.

You can also discover more about our products by attending Surface Tech’s TRB Live! Theater. Be sure to mark our presentations on your meeting calendar:

Monday, January 14th – 9:30 a.m.
What is an ASCM and why do we care?
Jon Belkowitz, PhD, Chief Technology Officer, Surface Tech
advanced supplementary cementitious materialPortland cement concrete already incorporates a wide range of supplementary cementitious materials, including fly ash from coal combustion, and silica. However, these materials do not address all of the shortcomings of Portland cement in certain applications and environments. Alternative supplementary cementitious materials hold the promise of increasing the strength of concrete, requiring less water in the mix, improving workability and producing a concrete that’s less brittle. Surface Tech has been at the forefront of alternative binder technology since 2016. Come learn about JUNO XP. We are seeing spectacular potential for this product as an alternative supplementary cementitious material. We’ll explain how it can reduce cost and increase strength of traditional concrete in your next project.

The ideal asphalt cracking performance test — what is it?
Joe Dennis, Vice President & Chief Technical Officer, Surface Tech
Phil Blankenship, PE, BLANKENSHIP ASPHALT TECH AND TRAINING, PLLC
ACE XP Polymer FiberASCE recently gave U.S. roadways a dismal “grade D+.” One main reason for this poor performance is the premature cracking of asphalt pavements. This presentation will review a variety of cracking performance tests currently available, providing the strengths and weaknesses of each — including a review of the newest crack performance test called the IDEAL CT crack test. Since the availability of asphalt crack improving modifier options is limited, the presentation will also provide an overview of the capabilities of aramid polymer fibers to decrease this premature cracking of asphalt pavements.
