ACI Releases New Shotcrete Guide


The American Concrete Institute recently released a new guide to provide information on materials and properties of both dry-mix and wet-mix shotcrete.

Additionally, ACI PRC-506-22: Shotcrete—Guide reportedly covers most aspects of the shotcrete process including application procedures, equipment requirements and responsibilities of the shotcrete crew.

“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.”

According to ACI, the guide acts as a companion document to ACI SPEC-506.2: Specification for Shotcrete, discussing preconstruction trials, craftsman qualification tests, materials tests, finished shotcrete acceptance tests and equipment.

The document is reportedly 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.

ACI PRC-506-22: Shotcrete—Guide was released through the work of ACI Committee 506, which writes 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.

Previous Publication, Upcoming Conference

In December 2020, the ACI announced that it had released an updated version of its “Shotcrete for the Craftsman” publication.

The document provides professionals with an understanding of basic concrete technology and describes and illustrates how to properly place quality shotcrete. ACI reports that the content serves as the source content for the ACI Shotcrete Nozzleman and Nozzleman-in-Training certification programs and has since been combined with ACI 506.2, “Specification for Shotcrete,” and ACI 506R, “Guide to Shotcrete."

In the updated workbook, readers are be met with updated photographs, full-color figures, and a rearranged structure of the content highlighting the similarities and differences between concrete and shotcrete.

Last month, registration opened for the ACI Concrete Convention in San Francisco from April 2-6. Throughout the in-person event, ACI is expected to hold over 300 committee meetings, more than 50 technical sessions, an industry trade exhibition, networking events and more.

Technical and education sessions will reportedly be presented live with on-demand viewing available afterwards. Additionally, the sessions will be available to both those that registered for the in-person event or Virtual Technical Sessions.

Registration is currently open online and discounted rates are offered until March 31. A full convention preview can be found here.
