ACI Committee 212, Chemical Admixtures, has published a new state-of-the-art document, ACI 212.3R-16. This course provides an introduction that summarizes the changes in the updated document and explains in-depth four new chapters. These chapter include: Ch. 4 – Sustainability; Ch. 10 - Workability-Retaining Admixtures; Ch. 11 – Viscosity- and Rheology-Modifying Admixtures; and Ch. 21 - Admixtures for Pervious Concrete.

The contents of this course include five recorded presentations from the ACI 2016 Fall Convention:
• Introduction to the New State-of-the-Art Report on Chemical Admixtures by Bradley K. Violetta, BASF Admixtures
• Sustainability of Concrete Admixtures by Arthur T. Winters, Capitol Aggregates, Inc
• Workability-Retaining Admixtures: A New Class of Admixtures that Provides Consistency Control of Concrete by Joseph A. Daczko, BASF Corporation
• Viscosity and Rheology-Modifying Admixtures by Ketan R. Sompura, Sika
• Admixtures for Pervious Concrete by Dale Fisher, ProCure

1. Identify the important changes in the ACI 212R-16 Report on Chemical Admixtures for Concrete from the previous version.
2. Describe some different ways concrete mixed with admixtures, properly designed to improve concrete workability, finishability, strength, and durability properties, adds sustainability qualities to concrete structures.
3. Explain how workability retaining admixtures effects the concrete workability properties at the point of truck delivery.
4. Identify some effects viscosity modifying and rheology modifying admixture have on improving the workability of concrete.5. Discuss effects of some admixtures have on placing, compacting and finishing pervious concrete pavement.
