Rebar plays a vital role in boosting the life span of concrete. It has been used for many decades as a strengthening agent for concrete. Rebar is manufactured from various types of alloys and grades of steel. You can buy top grade steel from the very popular steel suppliers Brisbane. The exteriors of all the steel rods include ridges. The presence of ridges allows concrete to stick to the rebar. It also prevents concrete from sliding around inside the slab. Concrete may be strong under compression but it has weak tensile power. And, rebar can effectively boost the tensile strength of a particular structure.
Given below are some properties which makes rebar a great choice for reinforcing concrete constructions:
1. Smooth Expansion:
Soon after embedding in the concrete, rebar becomes thermal coefficient which is very much similar to concrete. Concrete and rebar must expand and contract at a similar rate. It is because concrete offers weak tensile power. Spilling may take place in case there is tension between rebar and concrete due to a difference in expansion rates. You should take into consideration the expansion while implementing rebar into concrete. And, always use rebar which offers strong protective features to bring down or eliminate corrosion or rust.
In case you spot rusting on rebar, do not panic. A little amount of rust should not be a cause of worry. However, you should notice if the rust is leading to a huge amount of corrosion in a bar. If it is so, the rebar may not be usable. Rebar reinforcement should be effective and satisfactory irrespective of the rust on the external side of the bar. The rebar reinforcement should meet the laid down standards in the industry. Check the standards of reinforcing mesh Brisbane. The level of rust should also come under the specified requirements for brush testing. If you notice rust on rebar, then follow the available standards before embedding in the concrete.
Though rebar is manufactured from metal, the real electrical conductor in a foundation is concrete. And, the concrete must always be grounded. The ideal way to ground the concrete is possible only by using rebar. It is also known as Ufer Ground. The key element is that rebar remains in close contact with the earth. In the absence of close contact with the earth, rebar will not be able to ground the foundation. Make sure you check all the guidelines before using rebar for grounding the concrete slab.
4. Low Magnetic Field:
Stainless steel rebar can effectively bring down magnetism and ensures that procedures or machinery within the building receives no disruption. It has emerged ideal for hospital, toll booths with electronic pass detection, laboratories, and medical facilities with MRI machines. You can contact leading stainless reinforcing mesh Brisbane to procure stainless steel rebar.
Concrete has emerged quite robust in compression but a little weak in tension. In order to compensate for this imbalance in concrete’s nature, rebar is cast into it. By casting rebar into steel, it can easily carry huge loads. The most common rebar in the industry is carbon steel. It consists of rolled shape round bars with deforming shapes. The other types of rebar may include stainless steel, composite bars manufactured from glass fiber or carbon fiber.
