Abstract:
Many factors such as mix design, batching, mixing and application influence the durability and strength of shotcrete. A shortcoming in any one factor can result in low quality shotcrete.

A comprehensive field research program is in progress to evaluate practical aspects of the behavior of conventional and experimental shotcretes. The experimental shotcretes are regulated-set shotcrete and steel fiber shotcrete, both of which have been considered promising for several years (Parker, et al 1971). Steel fiber shotcrete contains millions of one ince (25 mm) long steel needle-like fibers which provide improved flexural strength and considerable post-crack resistance.

An economic need necessitated the experimentation and development of a high production nozzle that had a low maintenance factor. With commercial nozzles, as production increased, the maintenance factor accelerated and the nozzle itself proved to be a limiting factor for higher production. The shotcrete was used for rock support in an 18' horseshoe tunnel and was used primarily by itself to make the rock support itself in lieu of using shotcrete with rock bolts or steel sets. All of our equipment is rail-mounded with a sliding floor, and a "California Switch" in each heading.
