Table of Contents
1. Explain the interaction among concrete proportioning, workability, and the amount of required consolidation energy necessary to successfully place concrete in various forms.
2. Identify other placement parameters that interact with the consolidation process to affect concrete workability negatively and positively.
3. Describe how different types and portions of sand and coarse aggregate interact with the consolidation energy needed to successfully place concrete
4. Describe examples of new concrete technologies that influence the consolidation process, such as higher-vibration vibrators and external vibrators.
