Concrete strength is an important point in the
building. Several materials have been used as an addition
to the common concrete mix to strengthen it, such as but
not limited to crumb rubber, polypropylene fibers, steel
fibers, and so on. The size of mixed material will not matter
much except for joint construction. Joint construction on
reinforced con-crete has a narrow material workspace
which makes the size of mixed material matter. This paper
will evaluate the strength of steel fiber over a narrow
space. From this evalua-tion, we conclude that increasing
the number and the length of the wire will rise concrete
pull strength but will lower its workability.
