Four kinds of fiber reinforced concrete are steel fiber reinforced concrete (SFRC), glass fiber reinforced concrete (GFRC), carbon fiber reinforced concrete (CFRC) and synthetic fiber reinforced concrete (SNFRC).
The first three kinds belong to high elastic modulus fiber concrete, in which carbon fiber has the best reinforcement and toughening effect, but its price is also the highest. Synthetic fiber is generally a fiber with low elastic modulus, which can only resist cracking, toughening, wear resistance and impermeability of concrete. The reinforcement effect is not obvious, but it is cheap and convenient to construct, so it is widely used in various panel projects.
