The American Concrete Institute, through the work of ACI Committee 506, has released ACI PRC-506-22: Shotcrete—Guide. The newly introduced guide provides information on materials and properties of both dry-mix and wet-mix shotcrete and covers most facets of the shotcrete process including application procedures, equipment requirements, and responsibilities of the shotcrete crew.
As a companion document to ACI SPEC-506.2: Specification for Shotcrete, the Guide also discusses preconstruction trials, craftsman qualification tests, materials tests, finished shotcrete acceptance tests, and equipment.
The document is written such that the numbering of all sections between the Guide and Specification documents are aligned, allowing ACI PRC-506-22 to serve as a non-mandatory commentary on the mandatory specification provisions.
“The newly revised ACI PRC-506-22: Shotcrete—Guide is an excellent primer for anyone interested in learning more about shotcrete materials, equipment, crews, placement techniques, curing, and protection,” commented Simon Reny, current Chair of ACI Committee 506. “The guide also details the benefits of shotcrete placement’s inherently improved sustainability. “
ACI Committee 506’s mission is to develop and report information on the use of shotcrete. Committee 506 has written and maintains several guides, materials, specifications, reports, and technical notes on the use of shotcrete in structural concrete applications. The main goal of Committee 506 is to develop better guidance for the acceptance of shotcrete on projects.
