Days 1 & 2 – Classroom Sessions
This 2 3/4-day Shotcrete Short Course, consists of two days of classroom presentations by highly accredited world-class shotcrete experts covering subjects such as:
- the current American Concrete Institute (ACI), ACI Committee 506 Specifications and Guidelines
- wet-mix and dry-mix applications
- hand-held and robotic applications
- mix designs and chemical admixtures
- reinforcement – various types and applications
- nozzleman certification and procedures
- pre-construction and post-construction testing
- proper shotcrete material handling and storage
- surface preparation and groundwater control
- auxiliary shotcrete application equipment
- measurement and payment
- safety program – planning and on-site implementation
- several case histories of successful shotcrete projects
Day 3 – Field Demonstration and Virtual Training
Day 3 will be a ¾ day of on-site field demonstrations at the Edgar Mine showing equipment being used, field testing, mixing and shotcrete being placed. Hand, as well as mechanical (robot) placement, methods of wet and dry mixes will be demonstrated. A major shotcrete equipment supplier will have a virtual simulator used in training proper shotcrete application available for attendee use.
The course will provide both classroom sessions and field demonstrations at an actual site thus the following should attend:
- Contractors – Tunnels, Shafts and Earth Retention Systems
- Engineers – Civil Design Engineers & Civil Engineering Field Supervisors
- Engineers – Mine Design and Operations Planning
- Individuals Involved in Construction Mgt. Services & Inspection
- Owner Representatives – Civil, Mining & Public Authority Officials
- Engineers in Training & Students w/ Interest in Civil & Mining Eng.
- Nozzlemen and certifiers involved in shotcrete application
The course will be an excellent opportunity for owners, engineers, suppliers, distributors and specialty subcontractors to meet and openly exchange information with shotcrete industry specialists:
- Shotcrete Manufacturers – Bulk and Prepacked
- Shotcrete Admixture & Reinforcement Suppliers
- Shotcrete Equipment, Wet & Dry, Manufacturers and Distributors
- Tunnel Support Manufacturers that Integrate with Shotcrete
- Concrete Pump Manufacturers for Wet Shotcrete Applications
About the DFI Tunneling & Underground Committee
The purpose of this committee is to identify and facilitate the advancement of new methods and technologies for design, construction, inspection, maintenance and operation of tunnels and underground systems. The committee will foster technology transfer among the owners, stakeholders, designers, contractors, and material suppliers involved in the use and construction of tunnels and underground structures. Collaboration will also be fostered with the academic community, equipment suppliers, and major tunnel contractors and owners to address research needs and knowledge gaps. It will also promote the education and training of students at the graduate and undergraduate levels, fostering and developing emerging industry leaders in this field of practice. Examples of technical focus areas for the committee include: conventional and mechanized excavation methods, design practices for tunnel liners, the use of new materials in construction, waterproofing and water control systems, contracting methods, and the allocation of risk and construction practices.
