Ferrocrete is derived from the words i.e. ferrous and concrete.
Ferrous means anything made from iron and concrete is made from cement, fine aggregates (i.e. sand), coarse aggregates (i.e. trap metal or broken pieces of stones), and water.
Here we will learn about ferrocrete, properties of ferrocrete & much more.
Introduction to ferrocrete:
Ferrocrete is sometimes referred to as ferrous concrete or rebar-reinforced concrete, combination of iron or steel and concrete, serves good complementary properties.
Iron or steel has a really excessive tensile strength which retains the ferrocrete from being stretched or bent to the breaking point, whereas concrete protects the construction from crushing because it has a really high compressive strength.
The primary component of concrete is Portland cement, ferro-crete is a higher early strength Portland cement.
Portland cement which is particularly suitable for:
- Facilitating the early de-moulding, handling and use of the precast concrete unit.
- Maintaining production in cold weather
- The early striking of formwork.
Properties of Ferrocrete:
Following are the various properties of ferrocrete as follows:
- Ferrocrete is chemically similar to Procem i.e. Portland cement.
- It is more finely grounded than Procem, hence it give-higher early strength properties.
- Also, stiffens and sets at a similar rate to Procem.
- It does not comprise any added accelerators or admixtures.
- Its colour is like Procem from the same works and different properties are much like Procem.
Advantages of Ferrocrete:
- It is less weighty than fiber-reinforced plastic (fiberglass), aluminum, or steel frameworks.
- It has lower strength and lower durability than standard RCC construction.
- Also, they are mechanically overloaded, it will bend rather than crack or break.
- It is 10 to 25% of the weight of a comparable construction made of bricks.
- The sleek sections make it more aesthetically attractive.
- It can be made in any size, so biological shape is possible.
Disadvantages of Ferrocrete:
- Construction is labour intensive.
- Skilled labour requires.
- Structures are less strong.
Applications of Ferrocrete:
- It produces high early strength in a wide variety of concretes, mortars and grouts.
- It facilitates the early de-moulding, handling and use of all kinds of precast concrete products.
- Also, reduces formwork putting instances.
- It helps to take care of normal concrete manufacturing throughout the cold climate.
Use of Ferro-crete Technology:
1. Ferrocrete purlins are designed as a logical alternative to factory-built systems.
The construction of the ferrocrete channel with simple modifications made into an extra viable, environment friendly and applicable building materials used along with MCR tiles.
2. Ferrocrete building likes floors, ceilings and walls for residential places and workplace buildings.
These ferments are fabricated using column, beam and panel systems that assist in the relaxation of cement and metal consumption.
3. Ferrocement ducts are appropriate for circulation of cool or hot air and they are structurally sturdy.
In addition, these are able to resigning atmosphere damages and they are superior to many of the conventional ones.
4. Ferrocement plated RCC structure is a heterogeneous material with voids and capillaries.
These are crammed with water causing spalling of concrete crack formations.
5. Ferrocrete water storage tanks are constructed using ferrocement plates of 25 mm to 30 mm thick.
The buildings are strong like metal plates and are completely waterproof.
6. Footbridge that is used to cross a road, rail track, these bridges are fabricated with supporting columns, stairs, roof and so on, as per requirement
7. Manhole covers which are superior in high quality and sturdiness as compared to the standard ones.
Heavy-duty as well as light-weight cover makes them excellent for busy locations.
It has the ability to stand for thousands of years, once set in high density.
