Durability has always been one of the main problems faced by reinforced concrete structures. In the traditional structure, the surface of ordinary concrete is naturally exposed, and its durability is low. At present, about 50% of the houses in our country have entered the aging stage, that is, 2.34 billion square meters of buildings are facing durability problems.

The easy cracking of ordinary concrete will not only affect the normal work of hydraulic structures, but also affect their durability. Sexuality and service life, seriously even affect the safe operation of the structure. The above points have always been difficult problems to solve in the construction and use of industrial and civil building structures, hydraulic structures, and harbor and sea structures.
