Nowadays, the use of concrete in the modern Australian construction industry has become prevalent. It is now a staple material across all types of construction projects in the country.
Concrete is used to build countless houses, commercial buildings, and other types of spaces, and it is the most commonly used material for laying the foundations of these structures. Manufacturers and researchers continuously discover new ways to optimise the inherent properties of concrete, so it’s safe to say that it will only bring even more progress in decades to come.
However, as great as concrete’s durability and utility may be, the one flaw with it is that it’s strong in compression but relatively weak in tension. This means that it is prone to cracks and yields, leading to a risk of structures falling apart. To maintain the stability of concrete structures, the construction industry relies on rebars.
What Are Rebars?
Reinforcement steel bars, commonly referred to as rebars, improve concrete’s innate tension and structural strength. Rebar compensates for the fact that concrete is weak in tension. With the use of rebar, you can ensure that your structure gains greater tensile loads and can withstand decades of stress.
Rebars are made exclusively from steel because its thermal expansion coefficient (elongation due to heat) is almost equal to concrete. When these two structures unite, there is much less potential for cracks and other types of damage.
How Do Rebars Add Strength to Concrete?
Manufacturers that provide steel reinforcing—such as Phoenix Reinforcing—follow a specific process to ensure safety and dependability at all costs. Concrete is evenly poured onto rebar frames, cages, or mats. Upon pouring, the concrete hardens and locks the stone or gravel in concrete while falling in place shortly after that.
This process results in a strong, mechanical bond where the concrete is locked with rebars well enough to ensure a much greater level of tensile strength. This means that any concrete sample will have excellent resistance against standard iterations found on the market today!
Can Rebars be Welded?
These forms of rebar can be welded:
Alow-alloy steel rebars: Alow-alloy steel rebars have a steel-to-carbon ratio that makes them optimal for welding. These welds can stay together under a significant load when sealed in concrete.
Welding rebars: Next to alow-alloy steel rebars, welding rebars have a rigid and strong structural connection that ensures feasible transportation and improved strength. When using these rebars, these practices and standards must be followed:
- Selecting the correct type of rebar
- Determining if it is necessary to preheat it
- Selection of the appropriate filler (welding wire or rod)
- Selection of a proper weld, preparation of metal, and the correct placement
- Selecting the best type of rebar for your needs
If you want to provide your structure with the greatest amount of strength and durability, there’s no doubt that reinforcement steel bars can pay dividends when executed correctly. With the help of these structural reinforcements, you can avoid problems concerning the foundation, walls, and pillars of your structures for decades to come!
