The different types of reinforced concrete

Reinforcing cement or concrete combines the relative strength of concrete with the higher tolerance to tensile strain, fatigue and impact resistance, and ductility of the material included in the composition. Because of this characteristic, reinforced concrete has been used extensively in the construction industry.

Below are some of the common types of reinforced concrete:

Glass fiber reinforced concrete (GFRC)

For more than two decades now, glass fiber materials have been used to reinforce concrete. Glass fibers, which consist of 200 to 400 individual filaments, are relatively inexpensive and have high resistance to corrosion. Because of its ductility, the structure of GFRC can be manipulated into big panels or intricate shapes. This makes GFRC one of the most conducive types of concrete for decorative applications.

Steel fiber reinforced concrete (SFRC)

Another common reinforcement for concrete is steel fiber, which comes in many forms (round, flat sheet, or deformed) and diameter or thickness (0.25 to 0.75 millimeters). SFRC is created by mixing hydraulic cement with steel fibers that are dispersed at random and placed along the cross-section of the concrete. The composite material has plenty of applications in construction.

Polypropylene fiber reinforced (PFR) mortar and concrete

Among the available polymers in the industry, polypropylene is not only one of the most inexpensive and abundant in amount, its physical and chemical properties also make it compatible with concrete and applicable in the construction setting.
