8:00 AM - 10:00 AM

Moderators: Narayanan Neithalath, Scott Z Jones

This is the second session, as a continuation from the session was presented in Las Vegas in Fall 2018. Interest in additive manufacturing (AM) or three-dimensional (3-D) printing is growing tremendously among different ACI committees. The session for Las Vegas was “Materials Science Aspects in Additive Manufacturing of Cementitious Binders” and dealt with fundamental materials science and processing of such systems. The session for Québec City presents challenges and opportunities for scaling of AM of concrete. The session will provide novel information to researchers, engineers, concrete producers, robotic system designers, and contractors to take AM from the lab to the field.
Learning Objectives:
(1) Discuss the challenges in additive manufacturing of concrete as it relates to materials and processes;
(2) Summarize the opportunities that AM provides, in constructing systems with unique architecture and/or performance;
(3) Synergize existing knowledge and open non-conventional avenues where concrete can be the material of choice, through unique advantages of additive manufacturing;
(4) Identify gaps to be bridged in taking AM from lab to the field, as well as the relevant stakeholders influential in enabling this transition.

Offshore and marine concrete structures have not received enough attention in the recent past, at least here in the United States. The complexity and safety concerns associated with these structures are such that they probably need more attention compared to many other types of concrete structures. Offshore and marine concrete structures are so global in nature that there is a higher need for better coordination and synchronization of design, construction, inspection, and maintenance practices in different parts of the world. This two part session will highlight the past, present, and future of this technology. Academics, researchers, practitioners, engineers, scientists, and manufacturers from all across the world will benefit from this session.
Learning Objectives:
(1) Develop an understanding of the nature and type of offshore and marine concrete structures;
(2) Identify unique features of offshore and marine concrete structures;
(3) Discuss variations in international practices related to design, construction, and maintenance of offshore and marine concrete structures;
(4) Summarize new and emerging technologies related to offshore and marine concrete structures.

9:00 AM - 4:00 PM

Moderator: Walter H Flood IV

This student competition aims to promote the idea of environmental performance in concrete mixture design as an important aspect of sustainability. The teams will have the mission to develop an innovative concrete mixture that must have the lowest possible environmental impact while maintaining optimal mechanical and durability performance. After designing their concrete mixture, teams are asked to perform a simplified lifecycle assessment (LCA) and present their results in a written report. At the competition, teams will have a poster to present their innovative concrete to the audience and judges, with an emphasis on environmental aspects considered in their design, and their mixture will be checked for durability by testing the resistivity. For more information on the competition and how to register, please visit www. concrete.org/students/studentcompetitions.


9:00 AM - 4:00 PM

Moderator: Walter H Flood IV

This competition will focus on workability and rheological properties of concrete. Teams are challenged to create a mortar mixture with optimum flowability and stability. Students are to mix mortar at the convention competition site and their mixture will be placed into a mold made in the shape of the letters “aci” from the top of the letter “a”. Both flowability and mixture stability will be evaluated. In creating their mortar mixture, teams will have to pay careful attention to the specified material requirements, just as concrete producers must meet specification and project requirements on a daily basis. Equipment provided by Humboldt and Forney. For more information on the competition and how to register, please visit www.concrete.org/students/studentcompetitions.

Several new binding materials are being promoted for use in concrete, both to enhance performance and improve the sustainability benefits of concrete. While mechanical properties of such systems are studied extensively, there is a lack of understanding in the engineering community on the response of such concretes at early ages, which influence constructability. This session is geared towards engineers and consultants, researchers, and concrete producers to provide state of the art results on the influence of the type and amount of binding materials on early age properties. Factors to consider when using concretes containing alternate cements (on which a new ACI committee has been formed—this is the first session to be co sponsored by this committee) will also be discussed.
Learning Objectives:
(1) Review the effect of physical and chemical properties of binders on early age properties including setting, strength gain, shrinkage, and cracking;
(2) Discuss guidelines on selection of appropriate binder systems for adequate early age properties and performance engineered concrete mixtures;
(3) Contrast the synergies between different constituent materials in early age response and how such synergies can be beneficially harnessed for better concrete performance;
(4) Describe how early age performance can be incorporated into concrete specifications for durable concrete.

Title: Concrete Structures in Marine Environments
The American Concrete Institute is honored to welcome Tor Ole Olsen, to The Concrete Convention and Exposition in Québec City, QC, Canada, as the International Lunch Guest Speaker. The objective of Olsen’s presentation will focus on the many reasons the future will see an increased use of the sea; mankind simply has to. Applications may be related to production of food, recreation, infrastructure, living, and rising of sea level. Fortunately, we know how to design and build robust structures; properly designed and built concrete structures behave very well in the sea. Examples of marine structures that will be described are offshore platforms for the oil and gas industry, strait crossings, renewable energy (in particular, wind), recreational, and fish farming. The presentation aims at showing what is possible to achieve with marine structures, and a little bit of what is required to do so. Tor Ole Olsen is a Structural Designer, predominantly focusing on concrete marine structures. Olsen has more than 40 years with Dr.techn.Olav Olsen, a Norwegian structural design consultancy. Olsen received his BASc and MaSc from the University of Toronto, ON, Canada; is the President of fib in 2019 and 2020; and is an honorary member of the Norwegian Concrete Association.

This session is co sponsored by RILEM Committee TC 267 TRM. Traditional test methods have significant limitations for evaluating the properties and performance of pozzolans in concrete. For example, the strength activity index does not truly capture the reactivity of pozzolans and their impact on concrete strength and durability, while the loss on ignition cannot reliably predict the impact on concrete air entrainment. This session introduces new and more reliable test methods to characterize the reactivity and performance of pozzolans in concrete. In addition, it presents laboratory and field studies of application of unconventional sources of pozzolans.
Learning Objectives:
(1) Recognize new test methods to measure the reactivity of pozzolans;
(2) Describe tests to predict strength development in concrete containing one pozzolan or a combination of pozzolans;
(3) Identify methods to directly measure the effect of pozzolans on air entrainment in concrete, instead of relying on loss-on-ignition;
(4) Compare new and unconventional sources of pozzolans and their performance in concrete.
