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.

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.

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.

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.
