Topic:  Is My Concrete Defective?  And what's the weather got to do with it?

Does a low strength test require automatic rejection of concrete? What about a weakened, cracked, or ugly surface? What does the code say versus your contract? These questions unfortunately arise in concrete construction and sometimes the answers aren’t clear. Complicating further is when the issues are caused by hot or cold weather. What is considered “hot” and “cold”? What do you need to do differently? Get some background, answers, and strategies to deal with these questions!

Presenter:  Larry Taber, P.E., FACI, Senior Structural Engineer, Black & Veatch Federal Business

Learning Objectives:

  1. What is the definition of low concrete strength per the code and per a typical contract?
  2. What is the statistical basis for the code requirements?
  3. When is removal of defective concrete required or perhaps recommended? What methods besides removal can be used for acceptance?
  4. What is considered hot and cold weather concreting and what additional requirements are often specified?
