Mass Concrete and Thermal Control Plans: Managing Heat of Hydration

Your spec is asking for a thermal control plan to manage concrete temperature. We can help! We have completed more than 800 thermal models for mass concrete in bridges, buildings, dams, and industrial structures. This includes 150 thermal models for the St. Croix Crossing Bridge in Stillwater, Minnesota.

Thermal control plans tell you the:

  • required temperature of the concrete entering the formwork
  • requirement of insulation or heated enclosure to maintain the differential temperature between the center and face, and
  • approximate length of temperature monitoring required before the member meets the thermal control specification.

After each mass concrete member is placed, Beton monitors daily temperature data and assists the contractor in planning for when the maximum internal or differential temperatures approach their specified limits.

Beton’s philosophy is that cooling tubes should be used only when absolutely necessary. We’d rather help you manage concrete heat output through low heat of hydration concrete mixture design, lowering incoming concrete temperature, and managing insulation and heated enclosures.
