This determines if the rebar being used meets published specifications, ensuring the quality of the product. There are various factors to be tested that fall into the following categories:
Why do we need different rebar sizes?
Rebar in concrete provides uniform structural integrity, even though concrete material is very strong in compression, it is almost completely devoid of tensile strength. Without reinforcement, this inherent weakness of concrete becomes obvious in the material’s behaviour as it will bend and easily fracture.
What rebar sizes should be used?
For small scale and domestic projects, rebar with diameters of 6mm, 8mm, and 10mm will usually suffice.
Yield Strength
Yield strength is an important consideration when designing rebar. This measurement indicates the overall strength of the steel. High yield steel is best used for heavy-duty rebar and has grade 500 reinforcement has a yield strength of 500 MPa (or N/mm 2 ).
Accuracy in placement and size of rebar
Extra care needs to be taken when placing the rebar before pouring the concrete. The yield strength of the concrete can be severely compromised if the placement is not correct. Precise measurements are crucial, mistakes of just a cm or two in rebar spacing can reduce the tensile strength of the concrete by up to 20%.

What is the maximum tensile strength of rebar?
Heavy duty rebar should be made from high yield steel with grade 500 reinforcement which has a tensile strength or yield strength of 500 N/mm2 (or Mpa). Under British Standard 4449:2005, the maximum yield strength permitted is 650 MPa (or N/mm2). It’s important to be aware, though, that changing the rebar size by increasing its diameter won’t make it doubly strong. While the yield strength will definitely increase, it is the grade of steel which will affect its strength more.
Why use stainless steel rebar?
When choosing reinforcing bars, stainless steel rebars are the best possible choice thanks to their extreme resistance to corrosion. Making concrete considerably more resistant to cracking and failure, stainless steel rebar provides additional tensile strength. This is why it is so important in structural concrete projects since it offers stronger support when compared with reinforcing fibreglass, steel wires or any other products available on the market today since it supplies structural strength itself.

Why use rebars in concrete?
Whether the project includes posts, walls or floor slabs, using rebars can help to prevent cracks from forming that could cause the project to fail. While all concrete will crack, by using reinforced bars, it becomes possible to control the extent of any cracking and where the cracking occurs, whilst providing greater structural strength for the project.
What is reinforced steel used for?
Reinforcement steel is widely used in the construction industry and while not every project using concrete needs rebar, it’s typically used when constructing mas onry and buildings since it supplies strength to the concrete while absorbing tension.
Can you use rebar before concrete?
Additional care must be taken during the placement of rebar before the concrete is poured. The concrete’s yield strength may be compromised severely should the placement be incorrect. It is absolutely crucial to take precise measurements since mistakes of only one or two centimetres when spacing rebars could reduce the concrete’s tensile strength by as much as 20%. Not only that, but choosing an incorrect size of rebar may result in a reduction in reinforcement by up to 35% and this could mean that insufficient reinforcement will be provided for the structure’s integrity and strength.
