Introduction to ShotcreteThe shotcrete process offers numerous quality, efficiency, and sustainability advantages, but proper knowledge of the process is critical to the creation of a quality specification and for the success of any specifier /owner employing the process. This presentation is an excellent tool for all involved in maintaining a high level of quality for concrete placed via the shotcrete method. Presentations can be tailored to cover specific topics, but a typical general presentation would include the following:

Chapter Technical Talks

Charles S. Hanskat, P.E. is the ASA Executive Director. He received his BS and MS in Civil Engineering from the University of Florida, Gainesville, FL. Hanskat is a licensed professional engineer in several states. He has been involved in the design, construction, and evaluation of environmental concrete and shotcrete structures for over 40 years. Hanskat is a member of ACI Committees 301, Specifications for Structural Concrete; 350, Environmental Engineering Concrete Structures; 371, Elevated Tanks with Concrete Pedestals; 376, Concrete Structures for Refrigerated Liquefied Gas Containment; 506, Shotcreting; and Joint ACI-ASCE Committee 334, Concrete Shell Design and Construction. Hanskat’s service to the service to the engineering profession exemplified though his involvement with American Society of Civil Engineers (ASCE), the National Society of Professional Engineers (NSPE), and the Florida Engineering Society (FES) in over 50 committee and officer positions at the national, state, and local levels was highlighted when he served as State President of FES and then as National Director of NSPE. He is a Fellow of ACI, ASCE, and FES, is a Board member for ACI’s Strategic Development Council (SDC) and a member of ASTM, AREMA and ASCC.

Shotcrete Today: Not Your Father’s Gunite

This presentation will introduce shotcrete placement ina wide variety of structural and geotechnical concreteapplications. Shotcrete is a time-proven method toquickly and cost-effectively place concrete with aminimum of formwork yet meeting or exceeding thestrength of form-and-pour concrete construction.Shotcrete inherently provides enhanced sustainabilitybenefits in comparison to form-and-pour concrete andallows the designer maximum flexibility in shape andthickness of their concrete sections. Attendees will gaina basic understanding of the capabilities and benefits ofthe shotcrete process in both new and repairapplications. The seminar will cover:

• Definition and History of Shotcrete• Shotcrete Processes (What’s wet-mix, dry-mix, gunite)• Shotcrete Applications• Shotcrete Sustainability• Environmental Conditions• Surface Preparation for Repair• Reinforcement Details• Shotcrete Mix Components• Shotcrete Placement Fundamentals• Finishes• Curing• Field Quality Control and Assurance• Qualification of the Shotcrete Team• ACI Nozzleman Certification• Useful Tools and Resources
