Concrete Plant 1 & 2 Recertification

Note: Beginning with the 2016-2017 Technical Certification Training Season, the Concrete Plant 1 Recertification and Concrete Plant 2 Recertification will be combined into a single course. Students who successfully complete the 1-day MnDOT Concrete Plant 1-2 Recertification class will receive credit for the MnDOT Concrete Plant 1 and/or Concrete Plant 2 certification only.

This class is for those who have completed Concrete Plant 1 and/or Concrete Plant 2 and are due for recertification. Students will review sampling and testing procedures along with review of corresponding MnDOT test requirements. The class will review updates to the MnDOT structural concrete specification including Certified Ready-Mix Plant requirements. Students will also have an opportunity to discuss lessons learned or concerns they may have with a concrete specification with the MnDOT Concrete Engineering Unit.

Prerequisites: Concrete Plant 1 and or Concrete Plant 2

Concrete Plant 1

This course is to train and certify technicians in concrete producing plants to meet the requirements of the Certified Ready Mix Plant Specifications. The instruction covers the sampling and gradation of aggregates as well as moisture determinations and batch adjustments. No laboratory work is included in this class. For certification, the student must pass a written exam with a score of at least 70%. Student must be familiar with calculations using a hand-held calculator.

Prerequisites: Aggregate Production

Concrete Plant 2

This course is for managers, quality control personnel, and inspectors in concrete producing plants who require Level 2 certification to meet the specifications for Certified Ready Mix Plants. The course will relate specific performance requirements to the concrete mix design and production controls to produce the specified mixes. The course covers ACI mix design procedures and specific MnDOT requirements as well as aggregate and admixture technology. MnDOT Plant 2 Certification will be based on satisfactorily passing the course examination and completing a detailed mix design.
