Currently the testing sprayed concrete (or shotcrete), both in the fresh and hardened state, is covered by European Federation of Producers and Applicators of Specialist Products for Structures (EFNARC), European specification for sprayed concrete, available from www.efnarc.org
and by
BS EN 14488, Testing sprayed concrete, which is divided into 7 parts as follows:
Part 1: Sampling fresh and hardened concrete Part 2: Compressive strength of young sprayed concrete Part 3: Flexural strengths (first peak, ultimate and residual) of fibre reinforced beam specimens Part 4: Bond strength of cores by direct tension Part 5: Determination of energy absorption capacity of fibre reinforced slab specimens Part 6: Thickness of concrete on a substrate Part 7: Fibre content of fibre reinforced concrete.
