This mini-session will provide an overview of AGC's recently published Decarbonization and Carbon Reporting Playbook. This playbook provides contractors with tools to communicate effectively with project teams and successfully navigate the complexities of carbon reporting for a project. It describes a process for identifying accountability, what to track and report, and how to do so. This is the first document of its kind written by contractors, for contractors, to help them assess the impacts of the projects they are hired to build.Understand the basics of tracking carbon emissions for a construction project, Identify who is responsible for each scope of those emissions, Determine how to track those emissions, andDetermine what are the best ways to cut jobsite emissions.
First time convention attendees are invited for a continental breakfast and brief session to orient you to the week ahead. Attendees will have the opportunity to meet other first time convention attendees, connect with convention mentors, and learn about what The ACI Concrete Convention has to offer.

This technical session is co-organized by ACI 564, ACI 236, and RILEM to disseminate information on scaling up of concrete 3D printing, with an emphasis on knowledge gained by the international community (in Europe, Asia etc. where concrete 3D printing is becoming more ubiquitous). These sessions are intended to: (i) disseminate the most recent information on scaling up of concrete 3D printing for different structural applications, and (ii) outline the challenges faced in printing real-world elements related to materials, printing system, architectural and design, structural testing, code compliance etc., and methodologies adopted to overcome those challenges. These sessions will incorporate international speakers who are at the cutting edge of research and development in concrete 3D printing, as well as practitioners who have implemented such structures in real world. The session is intended for professionals, students, and practicing engineers/architects.
Learning Objectives:
(1) Understand fresh properties relevant to upscaling 3D printing;
(2) Obtain an overview of optimization process with respect to 3D printing;
(3) Describe the mechanical characteristics of conventional and high performance 3D printed elements;
(4) Explore the applications of AI in 3D printing.
Ultra-high-performance concrete (UHPC) continues to impact the construction industry and its practical use is exponentially increasing. While significant effort in the past has been placed on material and structural research, as well as designing guidelines to effectively using the material in various structural and non-structural applications, quality assurance and quality control (QA/QC) of the material properties are equally important.
Due to the higher sensibility of the material properties in comparison to other cementitious composites, QA/QC towards various material properties needs to be tailored to this material.
This session will invite national and international research groups, material suppliers and contractors to share case their experiences and knowledge in the field of UHPC QA/QC.
Students will be challenged to apply sustainability concepts and use their knowledge of concrete mixture design to produce pervious concrete that balances permeability and splitting tensile strength. In addition, students will develop a mixture design that demonstrates cementitious efficiency—that is, maintaining the overall performance of the mixture with the lowest amount of cementitious materials.

Ultra-high-performance concrete (UHPC) offers revolutionary opportunities for sustainable building solutions. Although research efforts have shown that the development of mixture designs with lower carbon footprint is a successful avenue to impact the environmental footprint of this material, the overall impact of this material on the sustainability of building solutions with UHPC is just about to be explored.
Due to the material mechanical and durability properties novel building solutions with significantly enhanced sustainability can be designed. However, the quantification and evaluation are still challenging and might remain challenging in the upcoming years. Research emphasizing life cycle analysis (LCA) is under way to close part of the knowledge cap. This session will invite national and international research groups, material suppliers and contractors to share case their knowledge in new sustainable strategies of using UHPC technology.
