The need to construct concrete structures using sustainable materials and practices requires engineers, architects, contractors and owners to understand the sustainability aspects of structural lightweight concrete. This session will educate the audience on the latest information regarding the global warming potential of structures using lightweight concrete, including the material properties of lightweight aggregates and concrete and procedures for documenting GWP for projects. Case histories as well as new research will be included, covering GWP and service life predictions.
The session is relevant to ACI’s mission because it provides information on new technologies pertaining to documenting the sustainability of lightweight concrete and how to correctly apply existing technologies to analyze the GWP of a project.
Learning Objectives:
(1) Recognize that the total carbon emissions for a structure depend not only on the effects of production of the materials, but also on the beneficial effects of the material’s use in the project, such as the reduction in total material quantities resulting from dead load reduction;
(2) Identify and utilize the correct procedures for conducting life-cycle analyses for bridge decks constructed with internally cured concrete;
(3) Recognize the influence of internal curing using fine lightweight aggregates on the production of sustainable concrete;
(4) Explain the Federal Highway Administration’s EPIC2 initiative to encourage greater utilization of internally cured concrete to increase the service life of bridge decks throughout the United States.

Recently, there have been a lot of discussions about concrete mixtures being overdesigned for compressive strength. These strengths greatly exceed the ACI Specifications for Structural Concrete 301-21 required average strengths resulting in an increased carbon footprint due to much higher cementitious materials use and added cost to construction. The mixtures also have higher paste contents and other performance problems associated such as cracking, higher in-place concrete temperatures, shrinkage, creep, and alkali-silica reaction. In this paper, we discuss some of the reasons why concrete mixtures are overdesigned and offer some ideas of how the overdesign can be reduced.
Learning Objectives:
(1) Explain history and potential reasons for overdesign concrete mixtures;
(2) Review methodologies to reduce overdesign of concrete mixtures;
(3) Discuss negative impacts of overdesign of concrete mixtures;
(4) Describe potential performance issues associated with overdesigning concrete mixtures.

Mass walls are at risk. With energy codes continuing to escalate
insulation requirements and thermal bridging requirements, it can be harder for designers to justify constructing energy efficient buildings with thermal mass, despite its energy-saving benefits. Reducing operational energy is a key goal in overall carbon reduction for buildings. Recently published codes, ACI/TMS 122.1, 122.2, and 122.3, are valuable tools that can be used to ensure that mass walls meet energy code requirements. Speakers will demonstrate how the content of these codes are used for thermal bridging as well as using COMcheck and REScheck programs for code compliance.
Practical solutions for thermal bridging and insulation of concrete and masonry walls will also be discussed.
Learning Objectives:
(1) Develop insight into the history of U.S. Energy Codes and their favorable stance towards insulation versus concrete and masonry mass walls;
(2) Conclude that buildings built with exterior mass walls are energy efficient despite having lower R-Values than other, highly insulated exterior frame wall systems;
(3) Review what is in the three new joint ACI/TMS Energy Codes and how to use them to demonstrate energy code compliance;
(4) Recognize practical design examples and details of mass walls that are easy to build, economical and readily available across North America.
