Grouting is the application that we utilize a mix of cement
and sand along with other material (such as epoxy) to fill
the spaces that may result during some construction
operation. for example, one type of prestressing in
concrete is the post tensioning process. In this process we
install tubes in concrete beam or slab then we cast
concrete, after concrete hardening we insert steel strands
inside tubes for prestressing. the space that will result
between steel strands and inside wall of the tube is filled
afterwards by grouting.
Grouting is mainly used for filling the spaces rether than
to hold any main stresses.
