• I-74 Mississippi Bridge Replacement

    PROJECT PROFILE

Low temperature delivered over 36+ hour pours for high specification concrete on complex piers and footings

Project

  • 55° F / 10° C
  • I-74 bridge expansion over the Mississippi River
  • Anticipated 99,900 vehicles per day
  • Customers: Major Ready Mix Producer and State DOTs

Challenge

  • High specification concrete on complex piers and footings
  • Previous liquid nitrogen application over-promised and under-delivered, costing the customers time and money.
  • Slow barge to point of placement
  • 100 yard/hour (91m3/hour) pours

NITROCRETE™ ADVANTAGES

NITROcrete™ delivered low temperature concrete over 36+ hour pours, ensuring that the customer maintained cooling during slow transport to the point-of-placement, and kept schedule compliance with the desired 100 yard/hour batch rate.

Even as ambient temperature rose throughout the pour, automation kept temperature controlled without slowing down operations for cooling

About NITROcrete™

NITROcrete is the world leader in concrete temperature control. In 2012, what started as a jobsite problem for a partner evolved into a solution that is revolutionizing the concrete industry. The team listened, tested, developed prototypes, and made adjustments. Then they listened more, tested more, and in 2017, after 5 years of R&D, they introduced NITROcrete, a comprehensive concrete solution born directly out of the concrete industry.

The largest concrete companies in the world now use NITROcrete to simplify their processes, streamline their operations, and grow their bottom lines. NITROcrete provides a comprehensive concrete solution–cooling, system management, and support–which gives its worldwide industry partners unmatched efficiency, control, and peace of mind.

Advantages

  • Delivered low temperature over 36+ hour pours
  • Met desired 100 yard/hour (91m3) batch rate
  • Customer recieved unmatched support from NITROcrete™ temperature control experts

Toronto: mass concrete and high performance mix design on CIBC Towers

Long, unpredictable transit times and locally produced high-temperature cement presented challenges for constructing two center core structure towers in Toronto.

Atlanta Mass Concrete: Speeding Up Production Rates

In 2020 in Atlanta, faster pour times and the more consistent mix led to significant cost-savings for both the Ready Mix Producer and the Contractor.

Six-Figure Savings by Eliminating Concrete Cooling Tubes on Harbor Bridge

Corpus Christi's iconic Harbor Bridge required mass concrete for 500-foot tall towers. High humidity and ambient temperature required extreme temperature control to avoid complications with the concrete in the forms. NITROcrete™ enabled the project to meet temperature specifications without concrete cooling tubes, saving time and expense.
