Check this read on commonly used corrosion-resistant construction materials
When metal is exposed to moisture, air, saltwater and other environmental factors, it causes them to degrade and weaken over time – and this process is known as corrosion. Construction companies prefer corrosion resistant construction materials because corrosion can impact the structural integrity of a structure and can lead to complete failure. When construction materials are exposed to harsh environmental conditions, they can corrode, leading to structural damage and safety hazards. This is particularly concerning for infrastructural projects such as buildings, dams, bridges and other construction that need to withstand harsh environmental conditions. Over here we discuss some of the common corrosion resistant construction materials :
- Stainless Steel: Due to its high chromium content, stainless steel forms a protective oxide layer that resists corrosion. Stainless steel is highly durable and strong. It is widely used in structural constructions such as columns, beams and braces. Stainless steel sheets are also used in cladding and roofing to enhance the aesthetic appeal of the construction. Their durability and resistance to adverse climatic conditions also make them a popular choice for building bridges, handrails and facades.
- Aluminium: Construction companies use aluminium due to its lightweight and its corrosion resistant properties. resistance to corrosion. Aluminium forms an oxide layer on its surface when exposed to air, which protects it from natural corroding substances such as moisture, salt and acidic substances. It is popularly used for roofing, gutters, and siding. Aluminium is also used in beams, columns, and trusses due to its light weight and strength. In addition to roofing and cladding, aluminium is widely used to manufacture doors and windows. Since aluminium is easy to work with, it is used to build curtain walls, which are non-load bearing walls that let in natural light while also maintaining optimum insulation throughout the year.
- Galvanised Steel: Galvanised steel is coated with a layer of zinc, which makes it an excellent corrosion-resistant material. It is widely used in different outdoor applications, such as fencing, roofing, handrails, balustrades and lighting poles. Galvanisation is the process of coating galvanised steel with a layer of zinc. The zinc coating acts as a sacrificial anode and corrodes first when exposed to moisture and harmful chemicals, protecting the underlying steel from corrosion. The process of galvanisation makes galvanised steel a popular choice for construction and industrial applications.
- Concrete with corrosion-resistant additives: Concrete is not inherently corrosion-resistant. However, when special additives are used in the correct proportions and under the right conditions, they can significantly improve the corrosion resistance of concrete. A few of these additives are:
- Corrosion inhibitors: Corrosion inhibitors are added to concrete mix or applied to the surface after concrete has been poured. They reduce the rate of corrosion by inhibiting the chemical reactions causing it.
- Waterproofing agents: It reduces the amount of water that penetrates the concrete, helping to prevent corrosion caused by moisture.
- Silica fume: A fine powder that is added to improve the strength and durability of concrete.
- Fly ash: A byproduct of coal-fired power plants, fly ash can be added to the concrete mix to improve its strength and durability.
- Stainless steel fibres: These fibres are added to the concrete mix to improve its strength and durability.
- Polyvinyl Chloride (PVC): PVC is made of plastic material and is commonly used in piping systems due to its inherent corrosion resistance property. It is a popular choice for construction applications due to its corrosion resistance, durability and environmental friendliness. PVC is resistant to corrosive chemicals, including acids and alkalis, thus making it ideal for use in chemical plants, water treatment facilities and underground pipelines.
- TMT bars: In recent years, the use of TMT bars with improved corrosion resistance has become increasingly popular in construction. In India, TMT bars are often referred to as “saria” in the local language. High-quality TMT bars are highly ductile, strong and are corrosion resistant. TMT bars owe their corrosion resistance to the presence of a protective layer of oxide on their surface. During their manufacturing, TMT bars are subjected to high temperatures and rapid cooling. It causes the outer layer of the TMT bar to harden. Also, due to the cooling process, a layer of oxide forms on the surface of the TMT bar. This oxide layer acts as a natural barrier that prevents air, moisture or other corrosive materials from penetrating to the underlying steel.
