Concrete Cooling and Finishability

Workability, Evaporation, and Concrete Temperature | NITROcrete

Hot weather concreting isn't for the faint of heart. We'd hazard a hypothesis that profanity on project sites goes up proportionally with ambient temperature. In short: hot weather concrete is difficult. A simple-sounding yet familiar problem, but one with a complicated explanation. Stubborn hot weather concrete causes challenges for a variety of interconnected reasons.

ADOT changes specification to include liquid nitrogen

“We often receive questions about the effects of liquid nitrogen on aggregates,” said Eric Van Dixhorn, NITROcrete VP of Engineering. “Arizona was invested in confirming the safety of pre-cooling methods of delivering liquid nitrogen to the aggregate — which differs from what people historically think of when they imagine LN for concrete cooling...

Reduce Carbon Emissions and Waste

A third-party Streamlined Comparative Life Cycle Assesment compared liquid nitrogen cooling with ice cooling; the results showed significant reduction in carbon emissions, harmful particulate matter, and energy consumption.

Stabilize Hydration Rate

Lower temperatures yield more ideal hydration for stronger concrete, among other benefits.

Reduce Plastic Shrinkage Cracking

NITROcrete™ helps control evaporation rate, reducing shrinkage cracking. By controlling temperature, year-round problems with plastic shrinkage are mitigated when...

VDOT Approves NITROcrete

After about a year of testing, NITROcrete is now approved by the Virginia Department of Transportation for safe use in concrete roadwork operations. With this, VDOT brings concrete cooling into the 21st century as an alternative to ice cooling

Safer for People, Safer for the Environment: Sustainability in Concrete

We're all working hard to ensure that improving infrastructure now also results in a safer future. Sustainability necessitates controlling the variables of concrete production to mitigate waste.

Seattle: Traffic threatened to stall a 950-yard-pour

300 yards into a 950-yard pour, traffic threatened to stall progress and rack up costs. NITROcrete™ loads held their temperature when others failed. Loads that spent 95 minutes in transit held temperature within specification.

Improve Workability

Prevent slump loss and maintain workability, even in hot weather concreting operations. By lowering the concrete mixture's temperature, crews face less hassle with finishing and placing concrete.
