BIOMEDICAL, BIONUCLEAR WASTE VAULT REQUIRED HIGH SPECIFICATION MASS CONCRETE Bionuclear waste leaves no room for error with high specification, mass concrete pours. NITROcreteTM delivered loads cooled in the 40°F/10°C range when an unexpected September heat wave threatened to ruin the customer’s high-spec job. Project Challenge Summary In the shadow of the Rocky Mountains, a ready…

When it comes to fresh benefits, a little liquid nitrogen can go a long way. When you think of liquid nitrogen and concrete, what comes to mind? Mass concrete? Systems that involve inserting equipment into trucks? Or a complex Rube Goldberg Machine-like system added to a concrete plant? If so, it’s time to take another look.…

Finishability and Concrete Cooling Quantifying the Perfect Spring Day for Concrete Construction Imagine an 84°F (29°C) day in Atlanta, Georgia. While some might call that a “cold front” late summer, it’s June. You wipe sweat from your brow and recall how long summer in Georgia lasts. It’s a long day of work, and a long…

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.

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.

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

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

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.
