Ferro cement is a form of
reinforced concrete using closely
spaced multiple layers of meshand/or small diameter rods
completely infiltrated with, or
encapsulated in, mortar.

Chemical admixtures used in ferrocement serve
purposes of
• water reduction, with strength and reduces
permeability;
• Air entrainment, which increases resistance to
freezing and thawing;
• suppression of reaction between galvanized
reinforcement and cement
