Does It Matter?","description":"In this episode, we take a closer look at the concrete mixture requirements structural engineers encounter in ACI 318. We explore where the familiar values for water-to-cementitious-material ratio, air content, aggregate size, cement type, and durability requirements come from\u2014and what they mean for the concrete we specify on our projects.&amp;nbsp;We discuss how ACI durability exposure classes influence mixture requirements, including maximum water-to-cementitious-material ratios, minimum specified strength, air entrainment, and other material requirements.&amp;nbsp; Guest Profile: Tyler Ley is a professor and concrete researcher whose work focuses on concrete materials, mixture proportioning, durability, cement chemistry, air entrainment, curing, and field performance. Through his research and educational work, Tyler has become known for making complex concrete concepts accessible to practicing engineers and for emphasizing the connection between concrete mixture design and real-world performance.
