Description
This recorded webinar from September 15, 2015 covers designing concrete mixtures, or more properly phrased – proportioning concrete mixtures, which seems like a straightforward process. ACI 211, “Standard Practice for Selecting Proportions for Normal, Heavyweight, and Mass Concrete” provides a series of equations and tables that leads the user through developing proportions for concrete mixtures. However, there is also a bit of an art to designing concrete mixtures. Particle shape and texture cannot be quantified but play a major role in concrete performance. This presentation will discuss the basics of proportioning concrete mixtures.
