Mix Design Hints for Shotcrete| Concrete Construction …
difference between a typical 3000 PSI mix and a typical 4000 PSI mix is that there is approximately 100 pounds more of cementious material and approximately 85 pounds less sand in the 4000 pound mix. Cement is the sliding agent in concrete; while sand is abrasive which therefore, makes the 4000 pound mix pump easier.
Concrete vs. Shotcrete, What’s the Difference? | Yoder
a major pump/line blockage can be very significant. It is the role of the engineer to design better concrete mixtures that will be easier to pump or pump over longer distances. The difficulty however, lies in defining what is a pumpable mixture or what are the mechanisms behind the transport of concrete under pressure in a tube.

CG-86 – Construction-Grade Grout – W. R. Meadows
Concrete is discharged from a ready-mix truck, placed on the ground or in forms and then must be vibrated for compaction. By contrast, the shotcrete process, whether using wet or dry material feed, does not require forming or compaction thereby enhancing design creativity and application flexibility, often resulting in a savings of time or money
