Mass Concrete & Thermal Control

Concrete cast in massive sections requires special consideration due to the increased heat of hydration and temperature rise after placement. Uncontrolled temperature rise can result in unacceptable surface cracks or internal damage to the concrete.

CTLGroup is a world leader providing consulting services related to mass concrete construction technology. Our mass concrete experts have helped countless contractors, engineering designers, and owners write, adapt, understand and work within specifications for mass concrete elements and structures. CTLGroup can help you develop project-specific thermal control plans based on our thermal modeling. If necessary, these requirements can be supplemented and verified through testing in our state-of-the-art concrete materials laboratory.

CTLGroup experts are frequently approached to address:

  • Thermal cracking
  • Use of slag or fly ash as a replacement for cement
  • Maximum concrete temperature
  • Allowable temperature differentials
  • Delayed ettringite formation (DEF)
  • Cooling pipe layout and design
