There is tremendous effort that is spent in the design of a sustainable concrete mix design from material selection (including novel carbon-neutral materials) to proportioning. On paper, the CO2 savings can be considerable. However, in practice, a major hurdle for any concrete is ability for the material to be properly placed and consolidated. This course will focus on bringing awareness to the impact workability can have on sustainability, and also to highlight practices that can ensure paper CO2 savings can be translated to actual CO2 savings.

The contents of this course include five recorded presentations from the ACI 2024 Spring Convention:
1. Innovative Admixtures to Achieve Both Sustainability and Workability with 1L Cements by Joseph Daczko, Master Builders Solutions
2. How to Find the Cement Dispersant to Minimize the Cement Content of Self-Consolidating Concrete - A Data Science Approach by Jae Hong Kim, KAIST
3. Concrete Sustainability in Motion: Environmental Benefits of On-Board Monitoring Systems for Ready-Mix Trucks by Pierre Siccardi, Command Alkon
4. Rebalancing the Risk Equation for the Ready-Mix Producer Through In-Transit Management Systems by Nathan Tregger, Verifi LLC
5. Mix Proportioning and Workability: How to Make Everyone Happy by Terry Harris, GCP Applied Technologies

1. Analyze mixture proportioning choices including admixtures that can improve sustainability without sacrificing performance.
2. Discuss practical advancements, including additives and novel cement dispersants for sustainability in low-cement mixes.
3. Identify novel uses of additives to impart improved rheologies for different applications while replacing cement.
4. Recognize the importance of on-board monitoring and in mixer trucks as well as in-transit management of mix trucks for waste reduction and CO2 savings while maintaining confidence in the final concrete properties.

Study the materials included in this module. Then, complete and pass the corresponding 10-question quiz with a score of 80% or higher to receive a certificate for 0.15 CEU (1.5 PDH).
