It can, however, contain other additives which might change the steel's properties.
Steel has the same strength in tension as it has in compression, unlike concrete.
We will perform two tests which can be related to steel. We will be using small aluminum beam specimens to simulate steel beams. The mechanics are the same only aluminum is more flexible than steel, so it is easier to see deflections with aluminum. We will perform the tensile test first. A cylindrical coupon made of steel will be placed in the tensile testing apparatus.
