The steel corrosion in concrete is one of the major problems of the construction industry in different countries of the world. This has led to high costs, even in developed countries. This problem has been very severe in developing countries as well as the countries bordering the Persian Gulf, and many concrete structures have been corroded and damaged in a short period of time. Studies in these areas show that if the right materials are selected, and the technically and climatically suitable concrete is designed, the skilled people are applied, and finally, if sufficient and appropriate curing is applied, many concrete problems will be solved.

Concrete and steel are two types of materials that are used today more than any other material for building various constructions, and it can be said that without these two, the progress of human societies would not be possible in the present form. They are used alone or as a supplement. Steel is easier to use than concrete because it is produced under carefully controlled conditions and its features and properties are determined and controlled by multiple experiments. However, concrete is produced and used in completely different conditions and based on different parameters such as type of cement, type of materials and weather conditions.

Lack of sufficient knowledge of the properties of concrete components, as well as production and consumption procedures, can lead to irreversible losses. Today, different types of concrete are produced and used with different materials, and each has its own properties and applications. Currently, different types of cement are produced, which contain pozzolan, fly ash, blast-furnace slag, iron furnaces, sulfur, polymers, various fibers, and various additives.

In recent years, limited use of non-metallic reinforcements has begun. However, research is ongoing on their wider application and the long-term performance of this type of reinforcement. These reinforcements, known as Fiberglass Reinforced Plastic (FRP), are made of various fibers such as Glass Fiber Reinforced Plastic (GFRP), Aramid Fiber Reinforced Polymer (AFRP) and Carbon Fiber Reinforced Polymer (CFRP) in sticky resin.
