The cement-based matrices for ferrocement may be subjected to modifications, e.g. by admixtures of polymers and resins to the fresh mix or by impregnation of hardened ferrocement. The modifications are aimed at particular improvements of the final product, mainly an increase of strength or impermeability. 

Crack control and resistance against local loads in ferrocement is improved considerably by the addition of fibres and polymers into the matrix com-...
