Yes, in fact, there is an alternative that is being worked on and will be adopted in the future, which is replacing (concrete reinforced with iron bars) with carbon concrete
Carbon fibers consist of very fine fibers, with diameters ranging between 0.005 and 0.010 mm, most of which are carbon atoms linked together in microscopic crystals parallel to the fiber axis, which makes the fibers very strong compared to their size
Each thread of carbon fiber consists of a bundle of carbon fibers. The fiber is a tube with a diameter not exceeding 10 microns and consists of carbon only
Scientists and researchers expect a bright future for the new material, especially in the field of rehabilitating concrete bridges and strengthening facilities, and iron-reinforced concrete may be completely replaced in the future by carbon fiber concrete
Properties of carbon fiber
It is not subject to corrosion over time and can last for two hundred years or more
It has very high rigidity relative to its weight
Its coefficient of thermal expansion is low
Its resistance to tension
Very great hardness
A conductor of electricity, and this is a positive and negative property at the same time
Resistant to stresses
Fire resistant
Its ability to conduct heat
