I was just thinking, is their a way to make steel qualities inherent in concrete, therefore eliminating the need for re bar?
There is an iron powder reinforced concrete flooring that improves abrasion resistance. However, you cannot get the tensile strength enhancement that is possible with rebar.
Mixing hot steel with liquid concrete would be very hazardous to your health. Steal in a molten state would flash the water in the concrete mix into steam and the steam would blow concrete and steel out of your mold. This would be about like being shot with a shotgun. This occurred in a steel mill near me some years ago on a rainy day when some steel splashed from a ladle and landed on a puddle of water, part of the siding was blown off the building and one worker sent to the hospital.
