Who Should Attend:

  • Precast Concrete Plant Technical Personnel/Inspectors
  • Batch Plant and Production Personnel
  • Anyone who would like a refresher on concrete materials science.

Overview:

Good control of concrete mix design is crucial to producing quality-precast structures. It is important for precast industry professionals, production facility technical and production personnel, to understanding concrete mix design. The first course is intended to train someone with a basic understanding of concrete so that they can create a concrete mix design meeting their company’s needs, or to evaluate the suitability of a mix for specific applications. This course is specific to needs of the Precast / Prestressed Concrete industry. We will explore the mathematics and chemistry behind creating an absolute volume mix design, and how the proper raw materials, sequencing, and production processes can yield high quality concrete consistently. Also, we will troubleshoot common mistakes in typical precast mix designs and how to avoid them, as well as adjust concrete mixes to compensate for negative external influences. SCC and Architectural concrete will also be covered.

Learning Objectives:

  • Select raw materials suitable for a specific application
  • Complete the mathematics to proportion a basic absolute volume mixture, as per ACI 211
  • Design both structural and architectural mixtures
  • Design and adjust self-consolidating concrete mixtures
  • Evaluate a mixture using statistical analysis
  • Troubleshoot plastic and hardened concrete issues

Sessions:

  • Materials – A discussion of various concrete constituent properties and how they affect the concrete’s performance, and suggestions for selecting materials for different applications.
  • Proportioning – A walk-through of the ACI 211 method of absolute volume mixture design, and a session of designing concrete, using a provided worksheet, from historical data. A mixture design Excel spreadsheet designed for this course will also be provided.
  • Durability/SCC – A discussion of materials and proportioning considerations for designing durable concrete. This session on self-consolidating concrete moves past the basics and gives practical suggestions on making consistent SCC.
  • Architectural/statistics – We revisit both materials and proportioning, but this time with a view to concrete aesthetics. Best practices are presented for proportioning the mixture and the sample approval process. Also, this session covers the basic statistical processes needed to evaluate the performance of concrete mixtures.
  • Troubleshooting – The concrete we design may exhibit performance issues at times. This session teaches how to identify the cause of several common problems, and what the solutions are.

NEW THIS YEAR! The Quality Control Summit

Wednesday, May 15th, 3:00 p.m. – 5:00 p.m. 

The Quality Control Summit was developed by the PCI Quality Enhancement Committee to aid in the development of personnel who will be employed by PCI producer members.

Who Should Attend:

  • Precast Concrete Plant Technical Personnel/Inspectors
  • Batch Plant and Production Personnel
  • Anyone who would like a refresher on concrete materials science
  • A certificate for CEU’s will be provided by PCI for attendees who are interested.
A presentation of the top 5 non-conformances found during the previous year’s certified plant audits will be given. This session will allow you to receive feedback and suggestions for addressing audit non-conformances that you need help with.

There will be a review of the Exceptional Precast Practices - Continuous Improvement in Best Practices program. The PCI Quality Enhancement Committee has developed a self-assessment and the steps that provide the roadmap and the milestones for continuous improvement.  Areas covered are:

  • Productivity
  • Personnel
  • Safety
  • Field Operations
  • Sales and Marketing
  • Sustainable Plant and Concrete
Join us to discuss how the program works, and how your company can get the most out of it.
