What is the Difference Between Ferrocement and Reinforced Concrete?

The main difference between ferrocement and reinforced concrete lies in the specific surface of reinforcement. Ferrocement has a much larger specific surface of reinforcement compared to conventional reinforced concrete. Here are the key differences between the two materials:

• Reinforcing Material: Ferrocement uses wire mesh as the reinforcing material, while reinforced concrete uses steel bars.
• Tensile Strength and Ductility: Reinforced concrete has low tensile strength and ductility, whereas ferrocement is a thin-wall reinforced concrete that is commonly constructed using hydraulic-small wire mesh.
• Construction: Ferrocement is created by applying reinforced mortar or plaster over an "armature" of Metal mesh, woven, expanded metal, or metal-fibers, and closely spaced thin steel rods such as rebar. Reinforced concrete, on the other hand, is a composite material made of cement, sand, water, and steel bars.
• Applications: Ferrocement is used to construct relatively thin, hard, strong surfaces and structures in various shapes, such as hulls for boats, shell roofs, and water tanks. Reinforced concrete is widely used in construction projects for structures like buildings, bridges, and roads.

Comparative Table: Ferrocement vs Reinforced Concrete

Here is a table comparing the differences between ferrocement and reinforced concrete:

Ferrocement is a type of thin-wall reinforced concrete that uses small wire mesh as its reinforcing material, while reinforced concrete uses steel bars. Ferrocement has a higher specific surface of reinforcement, making it stronger and more durable than reinforced concrete. Additionally, ferrocement has a lower self-weight and does not require skilled workers or frameworks, making it a suitable construction material.
