NRMCA Concrete Technologist Level IV Certification
September 10 – 17, 2021 (Exam September 20)
Registration Fee: Member $700; Non member $900
The next NRMCA Concrete Durability Course will be offered as an online course on September 10 – 17, 2021, with the exam on Monday, September 20.
The course will use presentation recordings from a previous offering of the course for attendees to access as their schedule permits. There will be quizzes and live sessions for review and Q&A during this period. Course handouts will be provided on the NRMCA online education portal. The exam for this course that provides the NRMCA Concrete Technologist Level 4 certification will be on September 20.
The course provides a fundamental understanding of the nature of cement and concrete as they relate to durability of concrete. Topics will cover cracking, alkali aggregate reactions, sulfate attack, corrosion of reinforcing steel, freeze-thaw durability and other aspects. A group exercise will be facilitated to familiarize attendees with the ConcreteWorks software used for mass concrete and service life prediction. The course also discusses the durability provisions in the Building Code – ACI 318-19 and how specifications can be structured to address durability. Comprehensive reference material is provided as course notes that is an excellent resource to concrete producers and associated technical personnel. Those with the NRMCA Level 3 certification obtain the NRMCA Concrete Technologist Level 4 certification when passing the exam offered with the course. It is not essential to have attended the NRMCA technical short course to attend the Durability Course. The course provides required learning units towards the technical track of the NRMCA STEPS certification program.
The following sessions are covered in this course:
- Introduction, Overview of Concrete Durability
- Nature of Concrete I: Hydration, microstructure & permeability
- Nature of Concrete II: Shrinkage & cracking
