Seismic Retrofitting: Spending to Save
Seismic retrofitting work is most often concerned with saving lives. But in cases of infrastructure, or historic structures, saving the structure, and making sure that it can operate after...
Fast-Track Stadium
The project team selected to design and construct Egypt's cable-supported Cairo Stadium Indoor Sports Complex in late 1989 faced a hard-and-fast deadline. Just 18 months later,...
Taming the Urban Underground
When designing and installing excavation support systems at a city construction site, be prepared to deal with the urban jungle. Tunnels and utility cables and pipes clog the underground,...
Masonry Carries the Load
Engineers frequently have preconceived notions about building materials. Masonry, for example, is commonly selected by architects for its color and texture, rather than by engineers for...
Design and Application of Integrated Shotcrete Linings for Underground Openings in Weak Rock Masses
Tunnels and caverns excavated in weak rock masses require special consideration in terms of shotcrete lining design. Shotcrete as a support medium for weak rock provides major benefits...
Guidelines for Shotcrete Support in Hard Rock
The writer is working on a handbook on shotcrete in hard rock. The work is sponsored by the Swedish Power Board, Development Division. The main contents are: Choice of shotcrete support...
Development of Mechanized Wet Mix Shotcrete Application in Norwegian Tunnelling Industry
From 1971 to 1980 wet mix shotcrete won the Norwegian market 100%. In the same period hand held spraying was replaced by hydraulic manipulators. From 1980 to 1986, steel fibre use increased...
Wet Mix Shotcrete Used in Subsea Tunnel Environments
To reject the claim that the use of accelerator in shotcrete reduces the compressive strength with time, lately cored samples were taken from an 18 to 19 years old concrete. A wet mixed...
Guidelines for Shotcreting and Current Development in the Wet-Mix Technique in Finland
Guidelines for shotcreting were written based on the literature survey and shotcreting trials. During shotcreting trials existing Norwegian and Middle-European wet-mix shotcreting concepts...
Austrian Guideline and National Report on the Use of Shotcrete
The purpose of this guideline is the standardization of quality and a uniform procedure for the production and testing of shotcrete from the technical and engineering point of view. In...
Practical Considerations on the Use of Additives for Shotcrete
Shotcrete is mostly used today for securing rock: in this capacity, it has solved many problems and has become a necessary aid. However, thedegree of utilization of the method is still...
