A good concrete or shotcrete repair must possess three prime charÂacteristics: 1) the repair material must be durable in an aggressive environment, 2) the repair must be well bonded to the substrate and 3) the repair must be as crack free as possible to efficiently protect any embedded steel reinforcement from corroding.
Repair of Bridge Elements Using Shotcrete
This article presents the essential elements necÂessary for successful remediation of bridge elements. It should be noted that all strucÂtural elements whether f om bridges or other strucÂtures can have certain commonality. However, with bridges, there are certain environmental characterÂistics that enhance the potential for distress. Bridge elements have a certain sensitivity to damage caused
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 geoÂmetrically 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 actuÂally been around for many years-the process of using shotcrete or gunite to rehabilitate old, damaged, or otherwise substandard existing sewers.
