Mass Concrete Consulting

---

Structures classified as mass concrete are found in many concrete projects.  Mass concrete presents unique technical and schedule challenges.  Engaging a knowledgeable mass concrete consultant early in a project can provide you with significant time and cost savings.
MJ2 Consulting staff have provided guidance and assistance for over 1000 mass concrete projects throughout North America and the world.  We've had the privilege to play a part in the construction of some of the world's most iconic civil engineering structures.
MJ2 Consulting provides the following services related to mass concrete:

• Development of concrete mixtures with a low adiabatic temperature rise
• 2-D and 3-D thermal analysis
• 2-D and 3-D thermal stress analysis
• Mass concrete thermal control plans/temperature control plans
• Development of alternative specification limits for mass concrete
• Design of cooling pipe systems including sizing pumps and chillers

MJ2 personnel are also active in development of standards and guide documents related to mass concrete construction.  The new ACI 207.1 document includes a new definition for mass concrete and an equation for estimating the temperature rise of concrete, both attributed to MJ2 personnel.
