AASHTO Publications Concrete Series: Basics of Cement Hydration (1 PDH) TC3MS009-15-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 covers how a concrete mixture changes from a plastic state to become a solid concrete slab in a relatively short period of time. Central to this transformation is a complex process called hydration, an irreversible series of chemical reactions between water and cement. 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) • Mix Design Principles (TC3MS007-15-T1) • Early Age Cracking (TC3MS008-15-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 portland cement concrete (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: • Understand the physical and chemical occurrences that happen during cement hydration; • Identify various factors that can adversely affect these occurrences; and • Recognize the different temperature changes during particular stages of hydration.
