Repair of Bridge Elements Using Shotcrete

This article presents the essential elements nec­essary for successful remediation of bridge elements. It should be noted that all struc­tural elements whether f om bridges or other struc­tures can have certain commonality. However, with bridges, there are certain environmental character­istics that enhance the potential for distress. Bridge elements have a certain sensitivity to damage caused

Shotcrete Reinforcement

Before the 1970s, shotcrete was reinforced either with conventional reinforcing steel welded wire mesh fabric, or in some in­stances with chain-link mesh or even chicken mesh. In the early 1970s the con-Dr. D.R. (Rusty) cept of steel fiber reinforced shotcrete

Rehabilitation of Sanitary and Storm Sewers Using Shotcrete

The infrastructure of the United States is crumbling above, below, and around us. A considerable segment of the public and private engineering community is currently engaged in solving a geo­metrically increasing problem with geometrically decreasing funds. The problem is often compounded since maintenance of public works facilities must be paid for using public funds. This article will introduce a process for solving these problems that has actu­ally been around for many years-the process of using shotcrete or gunite to rehabilitate old, damaged, or otherwise substandard existing sewers.

Dry, Pre-mixed Shotcrete Supply for Tunnels and Mines

Tunneling and mining projects use shotcrete primarily as a means of ground support. Immediate application of shotcrete provides stability of the working face, prevent­ing loose rock from initiating movement and thus permit­ting incremental advances of underground openings even in the worst ground conditions (type V rock) or clays.
