Title: Learn and Practice Skills that Promote Psychologically Safe Environments
Description:
The goal of having diversity on a team or around a table is to generate better solutions. But that only happens when everyone around the table contributes the best of what they have to offer. Psychological safety is the key. Join us for an interactive session where we will learn and practice skills that promote a psychologically safe environment.

Learning Objectives:
(1) Learn about GWP benchmarks and thresholds;
(2) Be introduced to performance-based specifications and understand how to incorporate into the design process;
(3) Learn how to approach bidding when trying to meet both structural performance and sustainability targets;
(4) Examine a case study where low-carbon concrete was used while attaining the necessary structural performance.

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) Learn 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.
Moderator: Mr Peter Tarara

The UHPC Certificate Program is being developed by ACI Committee 239-E to introduce the concrete community to field and laboratory testing of UHPC. The certificate program is being rolled out by Committee 239-E in three modules. An overview of Module 1, which focused on General Knowledge of UHPC, was presented at the ACI Spring 2023 Convention in San Francisco. In Fall 2024, Modules 2 and 3 will be introduced through special sessions that will focus on collecting samples, characterizing fresh properties, and testing UHPC to characterize hardened properties.
Learning Objectives:
(1) Describe procedures to fabricate specimens made of UHPC in the field and laboratory;

This session will include case studies that bring to light recent advances in the assessment and repair methods of segmental bridges.
Learning Objectives:
(1) Understand the unique design and construction aspects of segmental bridges;
(2) Discuss the key challenges with the inspection and assessment of segmental bridges;

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) To gain insight into the history of U.S. Energy Codes and their favorable stance towards insulation versus concrete and masonry mass walls;
(2) To learn that buildings built with exterior mass walls are energy efficient despite having lower R-Values than other, highly insulated exterior frame wall systems;
(3) To understand what is in the three new joint ACI/TMS Energy Codes and how to use them to demonstrate energy code compliance;
(4) To see practical design examples and details of mass walls that are easy to build, economical and readily available across North America.
