pdf Shotcrete as a good looking final finish—it is possible! Popular

ABSTRACT: Shotcrete has long been used in civil works for free-form structures such as swimming pools and vertical construction of embankment walls and slope stabilisation. The majority of this type of work is still applied by hand. One of the chief limitations to shotcrete being used as a final finish is the aesthetic quality of the finished product. To overcome this, a variety of surface finishes have been developed by leaders in the industry including trowelled, coloured and sculptured finishes. However, due to some well documented examples of poor shotcrete construction many urban planners, government departments, builders, consultants and perhaps also the general public, consider shotcrete to be an unattractive final finish. This paper examines the recent history of the use of shotcrete in public infrastructure in Australia and examines how the correct application of skill and technique can avoid these problems.

pdf Shotcrete research and practice in Sweden—development over 35 years Popular

ABSTRACT: In 1973 a large research project on shotcrete in hard rock tunneling was started by the Royal Swedish Fortifications Administration (FortF) and the Swedish Rock Mechanics Research Foundation (BeFo). That project was also the starting point for me on a long journey through a totally new landscape—the underground. In this paper the development of shotcrete practice in Sweden and its connection to research will be described. In 1973 neither bond testing, rock anchored reinforced shotcrete, fibre reinforced shotcrete or modern accelerators were known. Nor were high speed trains creating considerable loads from under- and overpressure on tunnel linings. The mode of action of shotcrete drains was not explored either. Today there is an increased need for better methods of crack prevention and improved knowledge regarding shotcrete subjected to blasting vibrations and the time-ependent development of material properties in shotcrete.
