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

By | Case Study - Concrete, Concrete | No Comments

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. 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 https://www.surface-tech.com/portfolio/juno/.

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.

How does Juno XP Impact the Glue of Concrete?

By | Concrete | No Comments

Juno ConcreteWhat is the glue of concrete?

Concrete is a mixture of aggregate, Portland cement, and water. But what actually holds concrete together? The answer is the hydrated cement matrix – the glue of concrete. Concrete is formed when Portland cement materials are combined with water to create a paste that binds with sand and rock to harden and form a composite structure. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore. These ingredients, when heated at high temperatures, form a rock-like substance that is ground into the fine powder we call cement.

The hardened cement matrix of the concrete composite is a porous and hardened sponge that provides the structural strength for civil construction as well as the backbone for durability and a long service-life.

The ultimate object of combining Portland cement with supplementary cementitious material is to increase the efficiency of the cementitious matrix, maintain and enhance the fresh and hardened properties.

Why do we care?

Concrete is one of the oldest and most reliable construction materials in the world. Concrete is at the foundation of our civilizations providing everything from the sidewalks in urban, suburban, and rural areas; to the enormous concrete dams, like the Hoover Dam, spillways, and locks.

In order to achieve the durability of concrete, large amounts of Portland cement are utilized. Although cement provides concrete binding, cement production accounts for 3-5% of the worlds CO2 emission.

Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. The manufacturing of cement is a long process and at every stage of its production, the environment is affected. Carbon emissions, water pollution, and release of heavy metals in the air are common problems associated with manufacturing.

Cement dust is a pollutant that affects both the health of people and plants. Chronic diseases and respiratory disorders are observed in people who work in a cement industry and are exposed to the cement constituents and cement dust. The setting of cement is a long process and it is alkaline in nature, which may lead to lung and skin disorders because of the excessive heat normally released during setting and curing (Cement Production, Hazards, and Recycling, 2011).

How does Juno XP affect the glue of concrete?

The proprietary and novel make-up of Juno XP effectively manipulates the molecular kinetics of cement hydration to increase the toughness and durability of concrete; making concrete stronger and last longer. The science behind Juno XP is a combination of pozzolanic and mineral materials that increase production of the strength-bearing microstructure. Juno XP also has a mechanical impact on fresh concrete and creates an environment that allows for a reduction of traditional cementitious material while maintaining the creaminess needed to allow grey concrete to go down the chute into the formwork.

Juno XP acts as a binder replacement to allows for a reduced the need for cement. Juno XP allows for the following:

  • Maintenance of fresh properties
  • Increase in Strength and Toughness of Hardened Concrete
  • Environment for Portland Cement reduction is created

Juno XP creates performance based concrete that delivers the same properties of traditional concrete with a reduction in both cost and environmental impacts. Juno XP, saving the world with all the concrete in it.

Why are alternative supplementary cementitious materials important to the construction industry?

By | Concrete | No Comments

alternative supplementary cementitious materialsThe invention of Portland cement 175 years ago heralded a new era in construction worldwide, and today it is the most widely used building material. Architects and general contractors appreciate its versatility, durability and economic value, and for its sourcing of local materials in production. That’s the good news about Portland cement.

The bad news:  Portland cement consumes vast quantities of energy and releases CO2 in the process. And since it’s produced in such gargantuan quantities, the construction industry faces increasing pressure to find alternative supplementary cementitious materials to replace Portland cement in concrete.

Portland 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. For instance, Portland cement concrete can degrade rapidly in environments with high acidity or high sulfate concentrations.

In addition to replacing Portland cement, alternative supplementary cementitious materials also 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. So naturally, the search for alternative supplementary cementitious materials to replace Portland cement has picked up speed over the past decade.

Surface Tech has been at the forefront of alternative binder technology since 2016. As Juno enters its final phases of testing and refinement, we are seeing spectacular potential for this product as an alternative supplementary cementitious material that will easily conform to ASTM standards and mitigate many of the problems inherent with traditional alternative supplementary cementitious materials.
