Shotcrete is used in retrofit work principally because it

  • A.is very much stronger than any concrete that can be placed in conventional formwork
  • B.requires no reinforcement of any kind behind the sprayed layer of material
  • C.adds no mass to the structure to which it is applied during the works
  • D.can be applied to irregular surfaces without formwork

Answer: D

Correct answer: can be applied to irregular surfaces without formwork

Existing buildings are irregular, and formwork against an old wall or an odd-shaped column is slow and expensive. Shotcrete is sprayed onto the prepared surface and the reinforcement behind it, following whatever shape is there. Its strength is comparable with placed concrete rather than superior.
