The objective of this session is to provide a greater opportunity for undergraduate students to present their research at a national meeting. This session will focus on research conducted predominately by undergraduate students. It is expected that this session will draw a new group of students to ACI and the convention. It will also allow students to hear presentations of a slightly less technical nature that are more in keeping with their current level of knowledge regarding concrete.
Learning Objectives:
(1) Recognize the quality and breadth of research being conducted by undergraduate students across the globe;
(2) Identify cutting edge research that is in its infancy as undergraduate students conduct pilot studies and plan for graduate research;
(3) Connect with talented undergraduate students who are seeking employment opportunities, graduate school positions, and professional mentors;
(4) Describe research on concrete materials, structural design construction, and other concrete related issues.


8:30 AM - 10:30 AM

Moderators: Kejin Wang, Kamal H Khayat

UHPC is attracting increasing interests worldwide due to its superior mechanical properties and excellent durability. However, the difficulties in handling of UHPC has been increasingly recognized as a major problem during construction because the significant workability reduction occurs due to very low water-to-binder ratio (w/b) and very high dosages of fine powders (e.g., silica fume) and admixtures (e.g., water reducing admixtures) used. It is well understood that mixing methods and procedures have more substantial effects on workability of UHPC than on that of conventional concrete. Ultra-high performance could not be achieved if required workability of UHPC does not met.
The main objective of this technical session is to uphold a platform to discuss the issues, challenges, and recent advances in characterizing, controlling, and improving workability of UHPC. It is also to promote broader dialogue and greater interactions between UHPC researchers and users.
Learning Objectives:
(1) Discuss major issues related to workability of UHPC in construction;
(2) Evaluate workability of UHPC;
(3) Identify major factors (e. g., use of silica fume and superplasticizer, and mixing procedures) that influence workability of UHPC;
(4) Predict effects of workability on properties and performance of UHPC.

Conventional design approach for self-consolidating concrete (SCC) results in mixtures with high binder content to secure proper workability. Reducing the binder content and clinker factor can lead to more Eco-efficient and economical SCC with lower thermal and drying shrinkage characteristics. The scope involves the optimization of granular bulk skeleton to minimize paste content and the use of adapted rheological approaches to optimize workability of Eco-low binder SCC. The use of recycled materials to enhance the sustainability of SCC will be discussed. Case studies using low-cement SCC and Extreme-SCC with very low binder content will be presented. Academic, industry, and agency representatives should attend this session.
Learning Objectives:
(1) Develop the mixture design and packing density optimization of low-binder content of SCC;
(2) Explain rheological properties and control of SCC;
(3) Describe performance of low-binder SCC from case studies involving major construction project in cold and hot climates;
(4) Summarize design and construction practices of sustainable concrete mixtures for building and infrastructure construction.

Join students and other ACI attendees for the Student Lunch with featured speaker David Lange. Lange’s keynote emphasizes that concrete is not a simple commodity material, but rather a complex one that demands the best students to enter the profession to keep the technology current. Research of concrete aims for “Eureka” moments that startle us, surprise us, amaze us. Those eureka moments represent leaps of progress. Incremental research is the opposite — a plodding, uninspiring approach— that may give us more information but does not do much to lift the human spirit. All are welcome to register for the lunch. Following the lecture, the results of the student competition will be announced.


1:30 PM - 3:30 PM

Corrosion of concrete in sewer infrastructures is a worldwide concern. Although the mechanism of this corrosion was discovered in the middle of last century, it was not a universal concern until the late 1990's. Since then, research has confirmed that the cause of this corrosion is a biogenic acid attack. Solutions for mitigation and testing processes for assurance have been developed. This session is for anyone interested in knowing exactly what causes sewer corrosion and what methods of mitigation are available.
Learning Objectives:
(1) Describe the biological mechanism that is responsible for the deterioration of concrete in some sewer infrastructures;
(2) Explain the how biological corrosion differs from traditional chemical and physical attack;
(3) Summarize mitigation methods to reduce the rates of degradation to concrete exposed to the effects of microbially induced corrosion;
(4) Identify methods to simulate the biological mechanism.

Mixtures designated as SCC may need a certain amount of consolidation to eliminate surface blemishes, to flow through congested areas, and to meet slump-flow loss during construction. Care has to be exercised in consolidating highly flowable mixtures such as semi-SCC and SCC since they can lose stability. This session will address the consolidation needs of semi-SCC and SCC and the effects of type and duration of vibration on the stability of these mixtures. There will be case studies and lessons learned. Researchers, engineers, contractors, and practitioners will benefit from the experience of the presenters.
Learning Objectives:
(1) Discuss the effects of vibration on concrete with various consistencies including SCC;
(2) Explain when and how to apply vibration to SCC mixtures;
(3) Discuss vibration of SCC for surface aesthetics;
