Presentation Description:
Proper mix design is the basis for the quality and cost of our products. This session sets the foundation for understanding basic mix design. In addition to learning what “specific gravity” is and its relationship to the volume calculations in a mix design, you will learn about “aggregate absorption” to help manage moisture in your aggregates during batching and how to apply these concepts to mix design calculations.
