The guide provides information on materials and properties of both dry-mix and wet-mix shotcrete. Most facets of the shotcrete process are covered, including application procedures, equipment requirements, and responsibilities of the shotcrete crew.
Other aspects, such as preconstruction trials, craftsman qualification tests, materials tests, finished shotcrete acceptance tests, and equipment, are also discussed.
“The guide is an excellent primer with numerous pictures and figures covering the entire shotcrete process for engineers, architects, contractors, inspectors, testing firms, material and equipment suppliers, educators, and students,” says Charles Hanskat, executive director, American Shotcrete Association and member of ACI committee 506, Shotcreting.
“A wide variety of applications and details of the shotcrete placement process are covered including history, equipment selection, material requirements, formwork, crew composition and qualification, proper placement techniques, types of finishes, QA/QC testing, and sustainability.”
Michael Tholen, managing director, Engineering and Professional Development, says the new guide, together with ACI 506.2-13, Specification for Shotcrete, provides the most up-to-date information available today, enabling the shotcrete specialist to complete projects in an efficient and safe manner.
“ACI Committee 506, Shotcreting, worked very hard to incorporate all the latest innovative practices into this document,” Tholen says.
“ACI’s role as a recognized leader in concrete knowledge dissemination is highlighted with this new guide.”
