While concrete has compressive strength, it lacks tensile strength. Without tensile strength, concrete structures would fall apart under certain forces. Rebar is embedded to ensure stability and allows concrete to withstand more force. Rebar comes in various grades with one of the highest being 100. Simply put, 100 grade rebar can carry 100,000 psi before experiencing its yield strength. There are several situations where 100 grade rebar would make the most sense, such as constructing a tall, slender column or beam that will experience a lot of tension force. In a slender structure, there may not be enough space to properly lay out a lesser grade. As seen in the image below, the structure is tall and slim. It would be difficult and inefficient to place several lower grade rebars. The higher the grade, the less rebar that needs laid. In a structure where space is limited but tension force is high, grade 100 rebar would be the best fit. ![](https://blog.krbmachinery.com/hs-fs/hubfs/33779-115084.png?width=413&name=33779-115084.png)![](https://blog.krbmachinery.com/hs-fs/hubfs/33779-115079-1.png?width=480&name=33779-115079-1.png) *The image on the left shows a slim structure where lower grade rebar would cause too much congestion. The right is an example of inefficiently laid rebar.* Grade 100 offers several other benefits. As previously mentioned, less rebar is needed when a higher grade is used. This results in lower placement cost and lower labor costs. Workers can get the job done quicker as they are handling less materials. ![](https://blog.krbmachinery.com/hs-fs/hubfs/33779-115081.png?width=802&name=33779-115081.png) *The high strength rebar on the right requires less material, resulting in less labor* Additionally, there is more efficient bar placement. Lower grade rebar needs placed closer together than higher grade. Arranging bars closely together can lead to crowding, slower construction, and difficulty placing concrete. ![](https://blog.krbmachinery.com/hs-fs/hubfs/33779-115077.png?width=863&name=33779-115077.png) *The above image shows how grade 100 rebar is the most space efficient and has the least congestion * Furthermore, Grade 100 will also deform less under pressure while carrying significantly more weight compared to other grades. Grade 100 allows for concrete structures to withstand high levels of tension while optimizing space and labor.
