Which rebar is best for concrete? This article will introduce you in detail which kind of steel bar is most suitable for concrete from many aspects?
Which rebar is best for concrete?
We all know that concrete is one of the most commonly used building materials in the world, widely used in the construction industry because it is low maintenance, durable, fire resistant and easy to work with.
But concrete has a terrible disadvantage that it can easily crack if a certain amount of force is applied to it. At this time, a very good choice is to use steel bars, and this problem is solved. So this creates concrete rebar. Simply put, rebar is used to strengthen concrete. They come in different lengths and thicknesses, threaded and unthreaded, so they bond very well with concrete, but there are many types of rebar on the market. Which material is the best choice? In fact, you can choose the most appropriate steel bar according to the specific use. At present, glass fiber reinforced polymer (GFRP) steel bar is a very popular steel bar. It is the same as carbon fiber , GFRP steel bars will not corrode under any conditions, but due to its high production cost, the price will be higher than other steel bars.
Why don’t we use stainless steel rebar?
Stainless steel rebar is expensive, although stainless steel rebar is about 1,500 times more resistant to corrosion than carbon steel rebar. Stainless steel is incredibly durable and flexible at the same time, but the main problem is that it is also expensive, which makes it rarer than any other type of rebar. But despite this, research has shown that: “Although stainless steel is known for its high corrosion resistance, corrosion can still occur. There are two main types of corrosion: general corrosion and localized corrosion (Gedge, 2008).”
Does fiberglass rebar rust?
Fiberglass rebar will not rust, and fiberglass rebar is corrosion resistant, lightweight, electromagnetically neutral, and a thermal insulator. Can be applied to structures where de-icing salt, seawater or other corrosive agents are used; projects sensitive to weight or heat; projects requiring electromagnetic neutrality and tunneling/drilling applications.
The advantages of fiberglass reinforcement are as follows:
Corrosion Resistant: Will never rust and is unaffected by salt ions, chemicals and the alkalinity inherited in concrete.
Light weight: It is about a quarter of the weight of steel bars of the same size, which greatly saves the cost of placement and use.
Electromagnetic Neutral: Contains no metals and will never interfere with the operation of sensitive electronic equipment such as medical MRI equipment or electronic test equipment.
Thermal Insulator: Efficiently blocks heat transfer.
What is the life span of GFRP?
GFRP has a lifespan of 100 years, and the benefit of using glass fiber reinforced polymer reinforcement is to reinforce a sustainable and long-term alternative that can withstand the corrosive environment where steel has a short lifespan, since it will not corrode.
