Academic and industry researchers, practitioners and students should attend this session to gain a historical perspective on the slump cone.
Learning Objectives:
(1) Discuss how the slump test has evolved;
(2) Identify what information can be obtained;
(3) Discuss the limitations of the slump test;
(4) Review different workability test methods for different classes of concretes.


8:00 AM - 9:00 AM

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.


9:00 AM - 3:00 PM

Students will be challenged to apply sustainability concepts and use their knowledge of concrete mixture design by producing pervious concrete that balance 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 material. For more information on the competition and how to register, please visit www.concrete.org/students/studentcompetitions.aspx.

10:30 AM - 12:30 PM

Moderators: Mohamed A Mahgoub, Ahmed Ibrahim

The earth's natural resources are being consumed at a very high rate for many years. The potential depletion of resources, CO2 emissions and high energy consumption rates in the process of production, increase the necessity of recycling. All sectors of the society are responsible for these concerns, especially the construction industry. As a major construction material. concrete is increasingly judged by its environmental impacts and reusing the readily available concrete is becoming very important. Considering that much of the US infrastructures and urban buildings now require renovation and replacement, the concrete left behind can be a valuable source of aggregate for new concrete. Such concrete is usually called Recycled Aggregate Concrete. Through cost analyses, it is shown that using recycling concrete as aggregate for new concrete production can be a cost-effective method for construction.
Learning Objectives:
(1) Raise public awareness of recycled concrete including its impact on reducing landfills and construction waste;
(2) Compare parameters of recycled aggregate concrete to natural aggregate concrete and evaluate the differences;
(3) Learn how recycled concrete can save natural resources and ecological environment leading to sustainable and greener world;
(4) Understand the effect of adding different construction waste materials to concrete and the effect of this on recycled concrete properties.


10:30 AM - 12:30 PM

Moderator: Lee Marsh

The objective of the session is to provide an overview of the newly adopted AASHTO Performance-Based Seismic Design guidelines for bridges. Bridge designers should attend this session, and learning outcomes include: the relationship of these guidelines with other AASHTO specifications, why they were created, examples of application, and potential knowledge gaps that ACI members may be able to help fill. This session is jointly sponsored by the Transportation Research Board Standing Committee on Seismic Design and Performance of Bridges.


10:30 AM - 12:30 PM

Moderator: Kay Wille

Ultra-high-performance concrete (UHPC) continues to attract more researchers, engineers, architects, students and experts across disciplines due to its fascinating material properties.
Over the last decades novelties have been shared in material design, mixing technology, material characterization and application, structural performance and design. While more innovations and novelties have been shared and exciting application examples being presented, more knowledge gaps, research needs and questions have been raised.

This session will invite national and international research groups, material suppliers and contractors to share new insights in UHPC technology, structural design and applications.

Learning Objectives:
(1) Learn about the carbon footprint of UHPC;
(2) Recognize its potential of environmental impact;
(3) Learn about new insights in the long-term behavior of UHPC;
(4) Realize opportunities about cost-efficiency.

Speaker: Santiago Pujol
Sozen’s Zen: Interactions with Japanese Researchers
In the 1920s, T. Naito in Japan had developed ideas about building design that were shown to be quite effective by the Kanto Earthquake that devastated Tokyo in 1923. Naito stressed the importance of stiffness in earthquake response. Few paid attention in the United States, where the focus was instead on strength. It took decades for the relevance of stiffness to be realized in the US. That was done again through interactions with the Japanese. The works of Takeda, Shibata, Shiga, Otani, and Shimazaki were key for Mete Sozen to formulate the ideas that drift should control design for earthquake demands and that drift can be controlled by increases in building stiffness. This presentation reviews those works and the original ideas of Naito to propose that international collaboration can speed up the urgent transformations required in our profession to cope with the challenges posed by: a) climate change; and b) expanding cities in which the public expects buildings to regain functionality soon after earthquakes.

12:30 PM - 1:30 PM

Moderator: Martin Noel

In the nearly 50 years since ACI 215R-74 was published, the design of concrete structures has changed considerably. The introduction of high-performance materials, greater design optimization, and/or increases in applied load levels result in higher ratios of live to dead loads. This session will introduce the new and completely restructured PRC-215 document as a resource for engineers designing structures that may be subjected to fatigue.
Learning Objectives:
(1) Recognize what content is covered in the new PRC-215 document on fatigue;
(2) Understand how this resource is intended to be used;
(3) Learn the basic concepts of fatigue and why it is an important consideration in the design of many concrete structures;
(4) Learn about the fatigue behavior of common constituent materials and components used in the construction of concrete structures.


1:00 PM - 3:00 PM

Moderators: Mohamed A Mahgoub, Yasser A Khodair

Concrete is the world's most widely used construction material. Yet, the production of portland cement, an essential constituent of concrete, leads to greenhouse gas emissions into the atmosphere. The production of one ton of portland cement clinker releases approximately one ton of CO2 and other greenhouse gases. Environmental considerations have been a major thrust for the sustainable development of the cement and concrete industries. A sustainable concrete structure is designed and built to have a positive environmental footprint during its entire life cycle. Concrete is increasingly being considered as a sustainable material owing to its low inherent energy requirements and little associated waste. Not only is it made from some of the most plentiful resources on Earth, it can also be made with numerous recycled materials and by-products and is itself entirely recyclable. Emerging breakthroughs in concrete technology have allowed producing ultra-high-performance concrete requiring less raw materials, along with structures that are much more durable to reduce maintenance, repair, and reconstruction.
Learning Objectives:
(1) Demonstrate how to evaluate recycled concrete mixtures with various waste-by-product and recycled materials;
(2) Recognize many different types of testing that could be performed on new concrete mixtures produced with recycled materials;
(3) Explain various methods to design and validate the concrete produced by new recycled materials;
(4) Specify emerging technologies in the concrete produced by recycled materials and its application in civil infrastructures.
