Abstract:
In 1974, the German Concrete Association published the DIN 18 551, Spritzbeton (Shotcrete) applying to all shotcrete jobs, especially for tunnel lining and maintenance of reinforced concrete constructions, The use of shotcrete for strenghtening and repairing of load-bearing concrete members was regulated in a special appendix to this norm, Recommendations for the Strengthening and Repairing of Reinforced Concrete Structures by Shotcrete, published in 1976 by the same committee. The application of this standard has brought a net increase in shotcrete quality as well as in the general use of shotcrete in the last few years in Germany.
