What Are the Properties of Ferrocement?
Ferrocement's properties distinguish it from conventional concrete. Few materials combine flexibility, thinness, and strength like ferrocement, making it an excellent option for curved structures or lightweight roofing systems.
Here are some of its key features:
1. High tensile strength due to multiple layers of steel reinforcement
2. Crack resistance and durability
3. Lightweight compared to conventional concrete slabs
4. Easy to mold into different shapes
5. Requires skilled labour for proper mesh placement and mortar application
What Are the Advantages and Disadvantages of Ferrocement Slab?
Every construction material has advantages and disadvantages, and ferrocement is no exception.
Advantages
Lightweight and easy to transport
Uses less cement and coarse aggregates
High resistance to cracking and impact
Ideal for thin-shell structures and retrofitting work
Cost-effective for specific applications like tanks and covers
Disadvantages
Labour-intensive; requires skilled workmanship
Susceptible to corrosion if the steel mesh is exposed
Not suitable for very large load-bearing structures
Difficult to repair once damaged
Requires precise quality control during application
Tips for Homebuilders Using Ferrocement Slab
Follow these tips to use ferrocement slabs effectively and boost durability and cost-efficiency in your home construction.
Ensure Skilled Labor: Hire skilled workers with experience handling steel mesh and applying mortar uniformly.
Protect Against Corrosion: Since steel mesh is prone to rust, ensure it's properly coated or that waterproofing is added, especially in humid environments.
Keep It Thin, But Strong: The appeal of ferrocement lies in its thin profile. Don’t overdo the mortar thickness; it defeats the purpose.
- Inspect Regularly: Early cracks or rust exposure should be repaired promptly to avoid long-term damage.
