This document is applicable to sprayed concrete to be used for repair and upgrading of structures, for new structures and for strengthening of ground. This document covers: – classification related to consistence of wet mix; – environmental exposure classes; young, hardened and fibre reinforced concrete; – requirements for constituent materials, for concrete composition and for basic mix, for fresh and hardened concrete and all types of fibre reinforced sprayed concrete; – specification for designed and prescribed mixes; – conformity. This document is applicable to wet mix as well as dry mix sprayed concrete. The substrates to which sprayed concrete can be applied include: – ground (rock and soil); – sprayed concrete; – different types of formwork; – structural components constituted of concrete, masonry and steel; – drainage materials; – insulating materials. Additional or different requirements may be needed for applications not within this document, for instance-refractory uses.<\/p>\n
