Lessons Learned from the Design, Construction and Operation of Hydroelectric Facilities
A Thousand Points of Data
Significant cracking was discovered in a multistory parking garage shortly after construction. Was it safe to open? Based on visual inspection, a bridge was down-rated, with potential...

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...
The Influence of Water Glass on the Technological Parameters of Shotcrete
Shotcrete used in tunneling must follow a clearly defined early strength development in order to comply with stresses from rock deformations and drilling and blasting. Accelerators are...
New Advances in Shotcrete Additives: The DELVO System
The DELVO system is a two component, nonchloride chemical system developed to control the dynamics of cement hydration. Concrete, treated with the DELVO system, can be kept in a plastic...
Advances in Dry Shotcrete Technology by Means of Microsilica
During the last decade microsilica has been increasingly used to improve both wet and dry mix shotcrete. In the traditional dry process microsilica is blended in the dry mixture. Since...
An Identity Chart for Steel Fibers
Improvements in ductility and toughness by adding steel fibers to the shotcrete mix are sufficient to enable steel fibers to be used as replacement for steel mesh reinforcements. Steel...
Use of Steel-Fiber Reinforced Wet-Mix Shotcrete in Extreme Rock-Bursting Conditions
If the stresses close to tunnels or caverns exceed the capacity of the surrounding rock, rock-bursting might start. When tunneling in such rock conditions the need for a safe, quick and...
Steel Fiber Reinforced Shotcrete?For Rock Support and Fire Protection
Rapid development in concrete technology and development of equipment has led to a change from dry hand-operated to wet robot shotcreting in Norway. Shotcrete of more than 100 MPa cube...
Steel Fibre Reinforced Wet Shotcrete with Very High Deformation Capacity
Tests have been carried out under site conditions in Norway where the performance of 40 mm long DRAMIX fibres was compared with normally used 30 mm fibres. The fibres were mixed into the...
