Concrete excels and boasts incredible strengths when placed in compression. However, did you know that concrete may only exhibit about 10% of its compressive strength when placed in tension? This is the primary reason concrete is often reinforced with steel. When used together, these two materials work in perfect unison to create incredibly strong and durable structures. During this course, we will discuss steel reinforcement best practices in precast concrete manufacturing facilities and reveal the technical reasons behind each important practice. This session is intended to provide pointed guidance for production, fabrication and QC staff and offer practical explanations to encourage continual use of reinforcement fabrication, placement and inspection best practices.
At the conclusion of this course, you will be able to:
- Describe proper reinforcement storage practices and how improper storage can negatively affect a precast product.
- Define “area of steel,” explain how to calculate it and outline what could happen if you have too little (or too much).
- Explain what concrete cover is, why the required amount of cover varies and how to achieve proper cover.
- Explain requirements for reinforcement bends and splices in different scenarios and explain how an improper bend or too short a splice can impact the structure.
- Discuss how to fabricate reinforcement into rigid assemblies and why rigidity is crucial.
- Describe the importance of reinforcement positioning and positioning tolerances.
