What Is The Primary Benefit To Construction Using Ferroconcrete? Ferroconcrete is a material in construction that has been around since the 1920s.
It’s made from steel and concrete which helps to make it durable and strong. This means it can be used for construction, as well as protecting other materials like fuel or oil in cases of emergency disasters.
There are many benefits to using ferroconcrete in both commercial and residential applications and this blog post will go over those benefits with you now!
What Is Ferroconcrete?
Ferroconcrete is a composite material that combines concrete and steel. In which both these materials participate in bearing.
François Coignet, a French industrialist, is considered a pioneer in combining ferroconcrete and precast concrete. Then, Coignet was the first to use iron for concrete when building civil buildings.
However, at this time, the purpose of Coignet when combining these two materials is just to help the concrete walls stand upright, not tilted, topple, not to increase tensile strength for concrete.
It wasn’t until the mid-nineteenth century that an English construction contractor named William B. Wilkinson gradually discovered the use of increasing tensile strength when combining steel and concrete.
However, it is Joseph Monier, a French gardener, who is known as the main inventor of ferroconcrete. Since then, ferroconcrete has been widely used in construction from small housing projects to large public works.
What Is The Primary Benefit To Construction Using Ferroconcrete?
Ferroconcrete is a popular construction material because of its strength, ease of application, adaptability, flexibility, durability and affordable price.
This material is commonly used for the construction of foundations for buildings, highway construction, floating structures, hydroelectric tunnels, irrigation canals, culverts and other prefabricated structures.
Ferroconcrete has good strength, tension as well as high compressive strength. Ferroconcrete composition is very popular all over the world, so the production cost is low.
Besides, maintenance costs are also low due to its high durability and good resilience.
Ferroconcrete can be cast in various shapes such as shutter configurations, formwork to form structures of desired shape, surface and size at construction sites. Fresh concrete in its liquid state should conform to architectural requirements.
Ferroconcrete structures are highly durable if properly designed and installed. These materials are not affected by the weather and they can last for hundreds of years.
Characteristics Of Ferroconcrete In Construction
Concrete shrinkage greatly affects the structure of ferroconcrete.
The steel bar will hinder the free contraction of the concrete as it hardens, causing tensile stress in the concrete and compressive stress in the steel bar.
The creep of the concrete will cause a redistribution of stress between the steel bars and the concrete, increasing the deflection in the flexural components of the reinforced concrete.
These properties of concrete must be considered when designing reinforced concrete structures. Only then can we create the strongest structure.
Due to the low ultimate tensile strength value of concrete (about 0.15 mm/m) and shrinkage of concrete, cracks are likely to occur in the tensile zone of the component in reinforced concrete.
To avoid concrete cracking and reduce crack width, prestressing method can be applied. Practice has proven that under normal environmental conditions, cracks with a width of less than 0.3 mm will not reduce the bearing capacity and durability of reinforced concrete.
In the temperature range of -40 to 60°C, the physical and mechanical properties of concrete and steel rods will not change significantly.
Therefore, reinforced concrete structures can be used in many different climatic conditions. When the temperature is higher than 60°C, the internal structure of the concrete material will be destroyed, its strength will be greatly reduced.
When the temperature reaches 200°C, the strength of concrete decreases by 30 to 40%. Therefore, reinforced concrete structures should not be applied in the environment where the temperature is above 200°C.
When the temperature exceeds 200°C, heat resistant concrete must be used.
What is every other common time period for ferroconcrete?
Ferroconcrete is likewise referred to as strengthened concrete. The time period comes from the Latin phrase for iron, which is “ferro”. It makes use of iron bars, referred to as rebar, to boost it.
What is the purpose of a suspension bridge?
They are best for protecting busy waterways. With any bridge assignment the selection of substances and shape normally comes right all the way down to cost.
Suspension bridges have a tendency to be the most pricey to build. A suspension bridge suspends the roadway from big most important cables, which enlarge from one give up of the bridge to the other.
What are disadvantages of ferroconcrete?
- Low bearing strength, not high ductility.
- The tensile strength of concrete is low and prone to cracking.
- Construction is affected by weather.
- It is difficult to strengthen and repair.
Ferroconcrete is a mixture of concrete and steel fibers. This material provides excellent tensile strength, which means that it can resist great amounts of tension.
It also has good compressive strength, meaning it resists the pressure from gravity or weight bearing forces placed on top of its surface area.
The main benefit to construction using ferroconcrete is the fact that it will not crack over time like traditional concrete does because there are no voids in this type of material for water to seep into and cause damage.
