Abstract – Ferro cement is one the advancement that is
happening in the field of civil engineering. It has low self-
weighted, and thus gives fewer loads on to the structures. In
this paper, we have studied different properties of the
Ferrocement like tensile behavior, cracking, compression, fire
resistance and impact Resistance. Based on Tests performed,
various applications and its benefits over normal cement will
be identified.
Key Words: Ferrocement, cement, tensile behaviour,
Material, Sustainable Development.
1. INTRODUCTION
Reinforced concrete is the most widely used construction
material in present age. Ferro-cement can be considered as
the origin and the first application of reinforced concrete.
Ferro-cement also called as Ferrocement was invented by a
Frenchman, Joseph Louis in 1848. Basically at that time
Joseph wanted to create urns, cisterns and planters without
the expense of kiln firing. Ferro-cement relates to type of
thin reinforced concrete consisting of large amount of small
diameter wire meshes distributed uniformly throughout the
cross section and cement mortar. Ferro-cement is a highly
versatile form of reinforced concrete possessing unique
qualities of serviceability and strength which cannot be
matched with any other thin construction material. Though
being the oldest and first of its kind use of Ferro-cement was
limited and not widely accepted. One of the reasons it was
not adopted widely was that the production technology
which was available at that time (19th century) was not
efficient to produce small diameter wires and meshes. There
production was more expensive as compared to large
diameter iron rods and thus a setback was created. During
world war reinforced concrete was used to manufacture
boats due to shortage of materials, particularly steel. As the
amount (volume) of steel required in Ferro-cement is more
as compared to reinforced concrete and as a result its use
was completely forgotten. During ͳ94Ͳ’s a known Italian
architect Luigi Nervi revived the original concept of Ferro-
cement, he found out components of Ferro-cement produced
material which have approximately homogeneous
mechanical properties and high resistance to impact. And
with time the durability and serviceability of Ferro-cement
ascertained and finally started achieving acceptance.
2. COMPONENTS OF FERRO-CEMENT
Ferro-cement primarily consists of cement, sand, wire
meshes and various admixtures. The main difference
between reinforced concrete and Ferro-cement is the scale.
Reinforced concrete uses larger size reinforcing bar as
compared to wire/meshes in Ferro-cement. Reinforced
concrete consists less volume of the metallic part as
compared to that of the Ferro-cement. It does not contain
large size aggregate as used in reinforced concrete only
cement mortar is used. Sometimes depending on the
requirement Ferro-cement may consists of large size bars
along with wire mesh. The number of layers of wire mesh to
be provided depends on the applications for which it is going
to be used. Typical cross sections of Ferro-cement are shown
in (fig. 1)
2.1 Mortar Composition
Portland cement is generally used in Ferro-cement. But the
type of cement to be selected should depend on its
application where to be used and in which environment to be
used. The sand to cement ratio is usually in the range of 1 to
2.5 by weight. And water to cement ratio is in the range of 0.4
to 0.6 by weight. In order to enhance the properties of cement
in wet and hardened state fly-ash, slag and silica fume should
be used. These minerals will also act as fine filler material.
Well graded sand from salt free source should be used. In
order to make sand penetrate in the reinforcement mesh the
maximum size of the sand particle should be one third of the
opening of the mesh. I
