AASHTO Publications Concrete Series: Mix Design Principles (1 PDH) TC3MS007-15-T1

This course offers professional development hours (PDHs). You will see the PDHs on your course completion certificate, which also serves as documentation of your attendance. PDH requirements vary, therefore, it is up to you to determine whether or not this particular course qualifies under your State or board requirements. Course overview: This module discusses mix design and mix proportioning. Mix design is the process of choosing the characteristics we are looking for in the concrete mixture. Mix proportioning, on the other hand, involves taking the information provided by the mix design process and using that information to determine the actual proportions of ingredients in the mixture. This course discusses theoretical, laboratory, and field testing to determine the portland cement concrete (PCC) mix that will achieve the best possible durability, strength, constructability, economy, and uniformity. This module is part of a curriculum from the "Integrated Materials and Construction Practices for Concrete Pavement" manual developed through the National Concrete Pavement Technology Center at Iowa State University. The other Web-based training modules include: • Design of Pavement (TC3MS003-15-T1) • Hardened Concrete Properties – Durability (TC3MS004-15-T1) • Fundamentals of Materials Used for Concrete Pavements (TC3MS005-15-T1) • Incompatibility in Concrete Pavement Systems (TC3MS006-15-T1) • Early Age Cracking (TC3MS008-15-T1) • Basics of Cement Hydration (TC3MS009-15-T1) • Fresh Concrete Properties (TC3MS010-15-T1) • Construction of Concrete Pavements (TC3MS011-15-T1) • QCQA for Concrete Pavements (TC3MS012-15-T1) • Troubleshooting for Concrete Pavements (TC3MS013-15-T1) Training level: This training is recommended for the Transportation Curriculum Coordination Council levels I and II. Target audience: This training is designed for agencies and their industry counterparts involved in the process to assure that the mix design and proportioning of PCC materials meet specification requirements and provide good, durable concrete. It is applicable to anyone desiring a better understanding of the mix design of PCC. Learning outcomes: Upon completion of the course, participants will be able to: • Describe the overall goal of mix design; • Define the difference between mix design and mix proportioning; • Recognize field and laboratory testing plans; and • Describe test methods used to identify incompatibilities.
