WEBINAR - ACI 207: Mass Concrete - How Big is Big?
Learn more270 WEBINAR - ACI 207: Mass Concrete - How Big is Big? 2021-04-22 09:00:00 2021-04-22 10:00:00 #f57921What is mass concrete? ACI 207.1R defines mass concrete as any volume of concrete with dimensions large enough to require that measures be taken to cope with the generation of heat from hydration of the cement and attendant volume change to minimize cracking. But how does one predict whether mass concrete problems will occur and what steps should be taken? This presentation will discuss how to identify mass concrete, ACI 301 requirements pertaining to it, and good construction practices.
The presenter will be Robert Howell, P.E. (Professional Development Program Engineer, American Concrete Institute)

WEBINAR - Mass Concrete Constructability
Learn more246 WEBINAR - Mass Concrete Constructability 2021-04-22 10:30:00 2021-04-22 11:30:00 #f57921Mass concrete (or thermally controlled concrete) typically requires implementing thermal control measures to reduce maximum temperature and mitigate temperature difference. Specified temperature limits and thermal control requirements can affect mix design proportions, materials selection, reinforcement details, construction operations and compliance to specifications for the work. Many specifications still limit concrete temperatures to overly conservative default values without recognizing concrete properties and performance that allow alternative temperature limits more suitable for the specified work while maintaining quality and improving constructability. This issue frequently results in challenging scenarios that create design difficulties and unnecessary constructability problems for mass concrete. This presentation focuses on the implementation of today’s knowledge of mass concrete and best practices to overcome mass concrete challenges and facilitate solutions in projects. A special emphasis will be given to the technical updates provided for mass concrete requirements and guidance progressing in North America industry standards.
The presenter will be Oscar R. Antommattei, MS, PE, FACI (Chief Concrete Engineer & Materials Engineering Manager, Kiewit)

ACI Post-Installed Concrete Anchor Installation Inspector
Learn more210 ACI Post-Installed Concrete Anchor Installation Inspector 2021-04-28 2021-04-30 #f57921THIS IS A TWO-DAY CLASS.
A certified Post-Installed Concrete Anchor Installation Inspector* is an individual who has demonstrated the knowledge required to properly inspect the installation of post-installed adhesive and mechanical anchors in concrete. The Inspector must understand the responsibilities and qualification requirements of the Installer, inspection requirements as cited in the documents governing the construction of the project, and the process governing the qualification of anchor systems.
*This expanded program includes and covers all of the Adhesive Anchor Installation Inspector program materials; certification candidates are now directed to this program for concrete anchor inspection certification.
Certification Requirements: ACI will grant certification only to those applicants who obtain a passing grade on both the written examination and performance examinations.

ACI Adhesive Anchor Installer
Learn more198 ACI Adhesive Anchor Installer 2021-04-28 2021-04-30 #f57921THIS IS A TWO-DAY CLASS
An Adhesive Anchor Installer is an individual who has demonstrated the ability to read, comprehend, and execute instructions to properly install adhesive anchors in concrete. The Adhesive Anchor Installer must also demonstrate possession of the knowledge to properly assess ambient conditions, concrete condition, materials, equipment, and tools for installing adhesive anchors and determine when it is appropriate to proceed with installation of an adhesive anchor or when additional guidance from a supervisor/foreman/project engineer is needed.
