Ferro cement is a type of reinforced concrete consisting of multiple layers of wire mesh embedded in a mortar matrix. It uses cement mortar, steel reinforcement like wire mesh or rods, and has a high ratio of sand to cement. The steel reinforcement provides strength while the cement mortar encases it. Ferro cement is a durable and versatile material with applications like water tanks, floors, pipes, and bridges due to its strength, impermeability, and ability to withstand impacts and deformation.

1. Ferro Cement
Ferro cement is a form of
reinforced concrete using closely
spaced multiple layers of mesh
and/or small diameter rods
completely infiltrated with, or
encapsulated in, mortar.
Material use in Ferro Cement
1. Cement mortar mix
2. Skeleton steel
3. Steel mesh reinforcement or
Fibre- reinforced polymeric
meshes

2. Cement Mortar Mix
 OPC and fine aggregate matrix
is used
 The matrix constitutes 95% of
the composite and governs its
behavior
 sand occupies 60 to 75% of the
volume of the mortar
 Plasticizers and other
admixtures are used
Sand:cementratio(bymass)1.5to2.5
Water:cementratio(bymass)0.35to0.60

3. Skeleton Steel
1. Forms the skeleton of the structure of 3 to 8 mm steel rods are used
2. Used in the form of tied reinforcement or welded wire fabric
3. Used to impart structural strength in case of boats, barges etc
4. Reinforcement should be free from dust, rust and other impurities
Skeleton mesh reinforcement
1. Consists of galvanized steel wires
of diameter 0.5 to 1.5 mm,
spaced at 6 to 20mm centre to
centre
2. Available as woven/interlocking
mesh and welded mesh
3. Welded wire mesh has
hexagonal or rectangular
openings
4. Expanded-metal lath is also used
5. Made from carbon, glass etc.

5. Properties of Ferro cement
1. It is a very durable, cheap and
versatile material.
2. Low w/c ratio produces an
impermeable structures
3. less shrinkage, and low weight.
4. high tensile strength and stiffness
5. better impact and punching shear
resistance
6. undergo large deformations
before cracking or high
deflections
