Steel reinforcement alternatives Part-I

For the past 100 years, reinforced steel bars have been dominating and still dominates the construction industry. The prime reason for that can be attributed to the properties of steel itself which is it’s high tensile strength and ductility ratio. Along with that steel has an almost similar thermal coefficient of expansion to that of concrete. There are many other advantages such as recycling that makes steel the preferred choice for reinforcement of building structures.

Why the alternatives

Usually, alternatives for a particular activity or procedures are introduced because either it introduces newer better ways to achieve the target or the new methods may be economically feasible than the current method for completing an objective. Here in the case of reinforced steel, certain alternatives have been proposed for the construction building structures.

Why do we need alternatives for something efficient and dominating as steel reinforcement?

Well, one thing to know is that steel production is not something that is cheap. It requires a lot of resources in the form of raw materials and money. With the recyclability factor of steel, it saves cost greatly, but sometimes the alternatives offer unique ways for achieving the target goal.

What are the alternatives

Some of the alternatives for steel reinforcement are Basalt reinforcement and Bamboo steel reinforcement. Now, let’s look at these two reinforcement alternatives and how do they differ in terms of benefits than steel.

Basalt reinforced bars

It is a type of reinforcement procedure in which Basalt rebars are used instead of steel for reinforcing concrete. Basalt rebars are generally tougher and stronger than reinforced steel thus having higher tensile strength. Basalt rebars are manufactured from basalt fibers by pultrusion technology. The surface is profiled and sanded. This results in better adhesion to concrete. Basalt rebars are 89 per cent much lighter than steel.

There are many reasons that make Basalt rebars as an alternative to steel reinforcement. Some of the reasons are it’s natural resistance to organic factors like alkali, rust and acids. The most interesting fact is that basalt rebar has the same thermal coefficient expansion as of concrete.
Another advantage of basalt rebar is that it doesn’t conduct electricity or induce fields when exposed to RF energy, which benefits MRI’s or data buildings. It is perfect for environments where corrosion is a serious concern. Basalt rebar is available in the following diameter sizes mainly 4mm, 6mm, 8mm, 10mm, 12mm and 25mm. Even with this much advantages, why is not commonly used as steel for construction of buildings,
