However, the effect of this rust preventive coating is limited by the permeability of the coating and the state of the concrete, and it requires a large area of coating, and the efficiency is low.

When the hydrogen-based material is hydrogen-rich water, the hydrogen-rich water is directly added into the concrete for use when the cement base material is used for manufacturing the concrete. The amount of hydrogen-rich water is calculated according to the amount of water required for concrete production. Generally, the amount of hydrogen-rich water is equal to the amount of water required for concrete production.
When the hydrogen-based material is hydrogen generating powder, 2-6 g of hydrogen generating powder is added into 1000g of gel material, and the hydrogen generating powder and the gel material are uniformly mixed to be used as a cement base material. The cement base material of the present invention is used for producing concrete according to a conventional method.

In addition, hydrogen can be attached to the surface of the steel bar, so that various chemical substances are prevented from entering, and the purposes of rust prevention and corrosion prevention are achieved. Furthermore, a large amount of tiny pores are formed after the concrete is cured, redundant hydrogen can be stored in the tiny pores to block the pores in the concrete, so that capillary channels are sealed, the invasion of various chemical substances is further prevented, and the purposes of rust prevention and corrosion prevention are achieved.
In the invention, when the hydrogen-based material is hydrogen-rich water, the hydrogen in the water can be attached to the surface of the steel bar and filled into the pores of the concrete, thereby achieving the same purposes of rust prevention and corrosion prevention.
