While shotcrete technology has been around for over 100 years, recent years have seen an explosion of the use of shotcrete in lieu of cast-in-place concrete in a wide range of civil engineering and mining applications. There have been major advances in shotcrete materials, mixture designs, supply, and application equipment, and shotcrete construction methodologies. The fundamentals behind such shotcrete design and construction, complemented by case history examples from different shotcrete projects on which the presenter has worked on, will be presented in this course.

Prerequisites

To benefit from this course the attendee should have a basic understanding of concrete technology and/or structural engineering design and reinforced concrete construction. The course should be of value to civil engineers, architects, academics, concrete inspection and testing technologists, as well as contractors experienced in reinforced concrete construction and infrastructure rehabilitation. It will also be useful for tunneling and mining engineers with experience in the use of shotcrete for underground support.

Course Description

While shotcrete technology has been around for over 100 years, recent years have seen an explosion of the use of shotcrete in lieu of cast-in-place concrete in a wide range of civil engineering and mining applications. There have been major advances in shotcrete materials, mixture designs, supply and application equipment, and shotcrete construction methodologies. Construction of heavily reinforced mass shotcrete structural walls and other other elements previously considered to not be possible to construct with the shotcrete method are now being built in North America and elsewhere using current state-of-the-art shotcrete technology.

Complex architectural curvilinear structures such as domes, shells, bobsleigh/luge tracks (which would be very difficult and costly to construct with cast-in-place concrete) are being constructed with the shotcrete process. Shotcrete is also widely used in infrastructure rehabilitation and seismic retrofit. The fundamentals behind such shotcrete design and construction, complemented by case history examples from different shotcrete projects on which the presenter has worked, will be presented in this course.

Learning Objectives

  • Basics of the wet-mix and dry-mix shotcrete processes.
  • Required characteristics of shotcrete making materials, including cements, supplementary cementing materials (fly ash, slag, silica fume, metakaolin, etc.), aggregate quality and gradation, fibre reinforcement (including steel and synthetic fibres), and chemical admixtures.
  • Fundamentals of shotcrete mixture design and performance requirements in the plastic and hardened phases.
  • Details of shotcrete equipment, supply and application.
  • Mass shotcrete construction methods and control of heat of hydration to satisfy peak temperatures and differential temperature gradients.
  • Use of the "Hybrid" (shoot and vibrate) construction method to construct complex heavily reinforced structural shotcrete walls and other elements with embedments.
  • Learn from case history examples of shotcrete use in construction of structures such as:
    • Structural shotcrete parkade walls.
    • Underground mass shotcrete station walls.
    • Permanent tunnel linings.
    • The many and various uses of shotcrete in underground mining.
    • Construction of curvilinear structures such as domes, shells, and bobsleigh/luge tracks.
    • Infrastructure rehabilitation of bridges, dams, and marine structures.
    • Seismic retrofit of historic masonry structures and other buildings.
    • Water retaining structures such as water tanks, canal lings, swimming pools, and spas.
    • Architectural shotcrete in artificial rockscapes, zoos, aquariums, monumental structures, and sculptures.

Target Audience

Civil engineers, structural engineers, materials engineers with concrete technology experience, architects, academics (undergraduate and graduate students and professors), concrete inspection, and testing technologists. Contractors specializing in reinforced concrete construction Tunnel and mining engineers.
