SHOTCRETE COMPOSITION
A shotcrete composition comprising a) a cementitious binder; b) an ettringite formation controller comprising (i) a glyoxylic acid condensate and/or a glyoxylic acid adduct; and c) an alkali-free, aluminum-based shotcrete accelerator. The invention further relates to a process comprising providing a cementitious composition comprising a) a cementitious binder, and b) an ettringite formation controller comprising (i) a glyoxylic acid condensate and/or a glyoxylic acid adduct; admixing an alkali-free, aluminum-based shotcrete accelerator to the cementitious composition to obtain a shotcrete composition; and applying the shotcrete composition onto a surface to obtain a shotcrete structure and allowing the shotcrete structure to harden. The invention also relates to a hardened shotcrete structure obtained by this process.
