At each ACI Concrete Convention the Women in ACI (WACI) provide two deserving young professionals with a Young Professional Convention Sponsorship. This award pays the convention registration fee for these young professionals to help foster their ACI “careers”. Since inception, the WACI has awarded over 17 Young Professional Convention Sponsorships. You are invited to support the Young Professional Convention Sponsorship program by attending the virtual Concrete Art Auction Sponsored by Women in ACI. Items featured at the auction have been donated by ACI members or created by university students. All proceeds of the auction benefit the Young Professional Convention Sponsorship. Visit the virtual auction site and check out the concrete pens, concrete desk accessories, and concrete decorative items along with t-shirts that support our Young Professionals’ participation in ACI!

There has been much discussion in ACI, and the concrete community in general, on the benefits of Internal Curing of concrete using pre-wetted lightweight aggregates. Internal curing can also be accomplished using other materials such as super absorbent polymers (SAP). This session, which is sponsored by committee 213, presents new research results on specific effects of internal curing, including: resistance to freezing and thawing; effects on self-consolidating concrete; results of electrical resistivity measurements; transport properties and pore water potential development; and corrosion-based service life prediction of reinforced concrete structures. These new papers are relevant to many aspects of concrete construction, including infrastructure projects. In order for the implementation of internal curing to continue to accelerate, the answers this session provides need to be widely disseminated. This is a direct reflection of the mission of Committee 213.
Learning Objectives:
(1) Specify requirements for internal curing materials and procedures that will result in satisfactory resistance to freezing and thawing;
(2) Predict the effects of internal curing with pre-wetted lightweight aggregates on the transport properties of concrete, including capillary pore water potential development and moisture content evaluation;
(3) Interpret the results of electrical resistivity of internally cured concrete;
(4) Evaluate the effects of reduced shrinkage cracking and reduced ion transport on corrosion-based service life of reinforced concrete structures.

Max capacity for a live session is 1,000. This session will be available on demand, during convention week, within 24 hours after this session takes place.

Most of the provisions for steel-concrete composite construction in the ACI 318 were removed in the 2019 edition. This leaves the AISC Specification as the primary standard for the design of composite members in buildings. The SEI/ACI Composite Construction Committee invites those who would like to learn more about the composite provisions in the AISC Specification to join this mini-session for an overview of the current provisions, differences from the ACI Code, and future directions.
Learning Objectives:
(1) Locate relevant composite provisions in the AISC Specification;
(2) Recall key differences between former ACI Code provisions and AISC Specification provisions for composite columns;
(3) Describe the benefits of the composite plate shear walls;

The word “sustainability” leads one immediately towards factors such as carbon emissions and renewable energy. But the true aim of sustainability, represented by the “three-legged stool”, is to find the balance between environmental impacts, economic costs, and the social benefits of any action taken. As we work to lessen the environmental impact associated with concrete construction, we often lose sight of the balance sustainability truly seeks. The goal of being “green” is often in direct conflict with either constructability, cost, or both. If sustainability is becoming more environmentally centric, is it necessary to start thinking of constructability and cost as being the other two legs of a new “three-legged stool”? How, as an industry, do we meet our goals of being good stewards of the environment while being mindful that a green design is of little social value if it cannot be constructed at a reasonable cost? In this session the speakers will discuss the design and construction challenges of being “green” while also trying to meet the necessary goals of constructability and “cost-ability”.
Learning Objectives:
(1) Describe how decisions to lessen the environmental impact of a construction project impacts constructability;
(2) Discuss how decisions to lessen the environmental impact of a construction project impacts costs;
(3) Identify decision points in design and construction where constructability and cost should be considered;
(4) Present examples where environmental goals were achieved without sacrificing constructability or cost.

4:00 PM - 6:00 PM

Moderator: John F Silva

The provisions for anchorage in ACI 318 (Ch. 17) have found increasing use for questions involving reinforcement anchorage, although an explicit formulation of splitting resistance is lacking. Conversely, the provisions for bar development, which focus primarily on concepts of bond and splitting, do not directly consider breakout failure modes that may be decisive, particularly in closely spaced bar groups. The use of, e.g., headed bars in groups terminating in sections with small edge distance, and the extensive use of reinforcing as anchorage in nuclear construction have raised questions about the adequacy of current provisions to provide adequate safety margins for all cases.
This session will focus on recent work to understand the behavior of reinforcing bars used for anchorage with respect to failure modes and predictive models, including cast-in reinforcing, post-installed reinforcing, high-strength reinforcing, straight bars, bars with mechanical anchorage (headed bars), and hooked bars. Behavior in normal weight, HPC, fiber-reinforced, and other concrete variants is included. The committee is asking for contributions that reflect both experimental, analytical, and code development work in this area.
Learning Objectives:
(1) Discuss the current code provisions on development and anchorage;
(2) Describe the overlap of anchorage and development in practice;
(3) Review current experimental and analytical work on anchorage of groups of straight, hooked, and reinforcing bars;
(4) Explain the background for potential changes to 318.

Accelerated bridge construction (ABC) heavily relies on prefabricated RC elements. However, the integrity of a bridge incorporating prefabricated elements depends on the performance of connections under service, strength, and extreme loads. New substructure and superstructure ABC connections are emerging to maximize the speed of construction and to reduce onsite activities.
Learning Objectives:
(1) Introduce emerging and proof tested ABC connections for both sub- and super-structures using conventional and advanced materials such as UHPC;
(2) Discuss bridge component and system behavior incorporating these connections;
(3) Synthesize design and construction guidelines for ABC connections;
(4) Review bridge component and system behavior incorporating ABC connections.

The need to further densify our cities has caused a continuous growth in the high-rise building market. This market demands not only high-strength concrete but also high modulus of elasticity, because deformations control many aspects of the structural behavior. This session will present several designers, constructors, and quality control experts sharing their perspective and experience on the challenges and current solutions in specifying, obtaining, and measuring modulus of elasticity of high-strength concrete.
Learning Objectives:
(1) Recognize the challenges faced in specifying high strength high modulus of elasticity concrete;
(2) Recognize the influence of the constituents and mixture design in obtaining a high modulus of elasticity concrete;
(3) Identify the challenges in quality control of Modulus of Elasticity and adequate ways to measure it;
(4) Review and learn from the experience of actual projects developed using high modulus of elasticity concrete.
