Date: May 25, 2022
Time: Noon – 1:00 pm CDT
Presenters: Travis Konda (Senior Technical Advisor, HNTB) and Mario Ratnaraj (Bridge Engineer, HNTB)

Description: Ultra High Performance Concrete (UPHC) describes a class of concrete material with a unique set of properties including: Strengths of 21,000 ksi plus, high ductility, low permeability and rapid strength gain. With these unique material properties, UHPC facilitates short development lengths, thin overlays and the potential for further development in optimized prestress girders for longer spans with less material. UHPC continues to play an important role in Accelerated Bridge Construction serving as the connecting material between precast elements allowing for small joints with short lap lengths while obtaining full connectivity between the elements. This presentation will introduce the audience to UHPC, the basic material properties, applications and lessons learned.
- 1. Define UHPC – what is it? What are the defining characteristics?
- 2. Understand the strength and subsequent reinforcement development
- 3. Identify applications for UHPC as part of Accelerated Bridge Construction
- 4. Establish an awareness of other UHPC applications and current developments
Travis Konda (Senior Technical Advisor, HNTB) Travis has 16 plus years of experience with HNTB as both a bridge designer and construction engineer assisting in the delivery of multiple Mississippi River bridge projects, including the Franklin Avenue rehabilitation project using ABC techniques.
Mario Ratnaraj (Bridge Engineer, HNTB) Mario has worked for HNTB for seven years as a bridge designer. He worked in the field helping to deliver the Franklin Avenue rehabilitation project.
About the Sustainable Structures Webinar Series
Now in its second year, the Sustainable Structures Webinar Series was developed cooperatively in 2021 by cast-in-place and precast concrete associations from the Midwest region of the United States including Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota, South Dakota and Wisconsin. The goal of the cooperative effort is to bring a greater awareness of the sustainable and resilient nature of concrete building systems to the design, construction, and development communities via quality continuing education programs.
Continuing Education Credits
AIA credits for these live webinars are being processed by the Minnesota Concrete Council – AIA Provider G538. Attendees will receive a certificate of attendance from the Minnesota Concrete Council for one professional development hour (PDH) within ten business days of the conclusion of the event.
