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...
