ACI SP-45:1974 PDF Download

ACI SP-45:1974 is a standard that was discussed at the Engineering Foundation Conference in June 1973. It is a compilation of 25 papers, 7 session summaries, opening remarks, a keynote address, the conference program, and a list of participants. The standard explores the use of shotcrete for underground structural support from the perspective of the owner, designer, and contractor.

The topics covered in the standard include the development of shotcrete for metro construction, shotcrete practices at the Henderson Mine, shotcrete applications in the Americas, European shotcreting practices, practical aspects of shotcrete application, shotcrete safety and environmental control, shotcrete design practices, selection/design of shotcrete for temporary support, geologic considerations in shotcrete design, and the use of special cements in shotcrete.

Furthermore, the standard discusses quality control and application of shotcrete, new developments in in-place testing of shotcrete, Corps of Engineers studies on shotcrete, early age strength properties of shotcrete, instrumentation to monitor behavior of shotcrete support systems, shotcrete durability and strength, shotcrete for structural rehabilitation, polymer shotcrete, and shotcrete case histories and specialties.
