8:00 AM - 9:00 AM

Moderator: Jason D Wimberly

The jointing plan for a concrete pavement is an integral component to the successful construction of a concrete pavement. Often, this step is not approved by the design engineer or entirely overlooked. This session will provide attendees with an understanding and explanation of the importance and examples for developing a sound jointing plan for concrete pavements.
Learning Objectives:
(1) Illustrate the importance of a properly designed joint plan which aligns with the construction methodology to be used by the contractor;
(2) Discuss the importance of coordination of the pavement joint plan with contractor.
(3) Describe techniques to properly design a pavement joint plan;
(4) Explain the importance of the pre-construction meeting on the success of the pavement construction and techniques to ensure a successful meeting.


8:30 AM - 10:30 AM

Moderators: Mahmoud M Reda Taha, Moneeb Genedy

This technical session aims to present the current state of the art in the formulation and applications of polymer concrete. The session will present the latest research finding on the use of nanomaterials to improve the rheological, electrical, and mechanical properties of polymer concrete. The session will highlight new research results showing the use of biopolymers to produce sustainable polymer concrete with a low carbon footprint. The session will also present the advances made in the use of polymer concrete for 3D printing. Finally, the session will explain the advances in using polymer concrete in bridge deck joints and overlays for accelerated bridge construction.
Learning Objectives:
(1) Discuss the use of polymer concrete for accelerated bridge construction;
(2) Evaluate the potential use of biopolymers to produce sustainable polymer concrete;
(3) Describe innovative methods for reinforcing polymer concrete using textile fabric;
(4) Recognize a new class of 3D-printed polymer concrete.

This session has been AIA/ICC approved for 2 CEU/PDH credits.


8:30 AM - 10:30 AM

Moderators: Mohamed ElBatanouny, Arezoo Imani

The objective of these sessions is to present and discuss different methods for detection and monitoring of surface damage in concrete elements. The focus is how to use SHM techniques to obtain useful information regarding formation and progression of surface damage. These sessions will be of interest to engineers, researchers, and infrastructure owners and operators.
Learning Objectives:
(1) Discuss the use tomography based sensors for structural monitoring;
(2) Review 'big data' analysis techniques and data fusion applications for NDE and SHM methods;
(3) Explain how to use imaging techniques for condition assessment of concrete structures;
(4) Define new sensors and applications for surface damage monitoring and imaging.

8:30 AM - 10:30 AM

Moderators: Kejin Wang, Surendra P Shah

Recently, many researchers have revealed that addition of nanoparticles can provide synergy to improve physical and chemical properties of concrete materials. Nanoparticles can act like fillers to refine pore structure and immobilize water movement in cement paste. They can function like seeds for CSH nucleation to accelerate cement hydration, thus compensating the delayed hydration and strength development caused by commonly used supplementary cementitious materials (SCMs) like fly ash in concrete. Many nanoparticles can also interact with SCMs to produce stable and/or cementing reaction products, thus further enhancing concrete strength and durability. The objectives of this technical session are to summarize the recent progress on the use of nanoparticles in cement-based materials containing SCMs, to have a better understanding of the synergic effects of nanoparticles and SCMs, and to recognize challenges in the use of nanoparticles in cement-based materials.
Learning Objectives:
(1) Investigate recent research progress and innovations resulting from use of nanoparticles in cement-based materials;
(2) Develop knowledge of the interactions between nanoparticles and supplementary cementitious materials and their effects on cement hydration and concrete properties;
(3) Identify the key issues in use of nanoparticles in cement-based materials;
(4) Discuss the synergy and benefits of use of nanoparticles in concrete containing supplementary cementitious materials.


8:30 AM - 10:30 AM

Moderator: Aron J Csont

Early definition of construction tolerance expectations is an important step in the design process of a project. Designs should consider tolerances of all materials and systems for their integration into a constructable facility. This session presents case studies, best practices, and material tolerances for design strategies to best achieve a constructible structure.
Learning Objectives:
(1) Review design considerations that generate a more constructable facility showcasing dramatic economic advantages to the project;
(2) Explain potential solutions to achieve a buildable facility, when current ACI 117 tolerances for multi-story structures are in severe conflict with other building systems such as elevators or exterior enclosure.
(3) Discuss research data on pavement depths which routinely exceed ACI 117 tolerances, without pavement failures and identify the other paving design parameters that may contribute to the success of the paving system;
(4) Identify critical, key components of a system such as void forms and focus on controlling these tolerances which in turn control our success.

This session has been AIA/ICC approved for 2 CEU/PDH credits.


9:00 AM - 5:00 PM

$35.00

The purpose of this workshop is to educate attendees on the newly developed ACI CODE 440.11-22 and the application of GFRP reinforced concrete in the construction industry.
Lunch will be served to the registered participants.
Participants will earn six CEUs/PDHs.

This workshop will provide an overview of FRP reinforcing bar properties, where they are commonly used, and how other standards from ACI and ASTM provide the foundation on which the new code has been developed. A discussion on where the code puts limits on the types of structures that can be reinforced with GFRP bars and where the code does and does not apply. The workshop will provide detailed discussion on the engineering of GFRP reinforced concrete for beams, columns, slabs, walls, and connections; determining flexural, shear, torsional, and axial strengths; and detailing GFRP bars for serviceability and durability. In the discussions, specific differences in designing with GFRP reinforcement versus steel reinforcement will be highlighted.
This is a great opportunity for engineers, owners, contractors, consultants, students, and manufacturers to get familiar with the technical and engineering aspects of the ACI 440.11 code and learn more about designing and detailing with GFRP reinforcement.

Learning Objectives:
(1) Identify basic material performance properties of GFRP reinforcing bars and how they compare to traditional steel reinforcement;
(2) Explain where the new ACI code for GFRP reinforced concrete applies, its limitations, and how it relates to other ACI & ASTM standards;
(3) Interpret basic mechanics of GFRP reinforced concrete in flexure, shear, axial compression, and torsion; how it compares to steel reinforced concrete; and the associated code requirements;
(4) Apply the basic principles presented to design concrete members and connections reinforced with GFRP bars.
