This module is based on two web sessions, “Decreasing the Clinker Component in Cementing Materials: Performance of Portland-Limestone Cements in Concrete in Combination with SCMs” and “Internal Curing Concepts in Mixtures Containing High Volumes of Fly Ash,” from the ACI Fall 2010 Convention in Pittsburgh, PA, explore the positive role concrete infrastructure can play in improved energy efficiency and reduced carbon emissions through the efficient use of green and cost-effective binder systems. Presentations include discussion of high-volume replacement of portland cement, including complex mixture designs; blended cements; and internal curing.
Table of Contents
1. Explain the sources of CO2 emissions during the portland cement manufacturing process;
2. Identify the current common limit, for many states, for fly ash replacement in concrete mixtures;
3. Compare the material property requirements for limestone blended cements and portland cements; and
4. Recall the tests used to evaluate shrinkage of concrete mixtures.
