Aug 03, 2016 · Well, that is far from the truth. In fact, corrosion can directly affect mechanical and structural properties of components. Corrosion can affect the global response of the structure. In this article, we will review some of the main structural effects of corrosion on steel structures and reinforced concrete structures. Read More
The chloride ions in sea water can also corrode steel bars to accelerate the damage of concrete. The anti-corrosion of concrete is improved by selecting appropriate cement varieties and enhancing the density of concrete. It is difficult for surrounding water to permeate the concrete with good density and closed pores, namely good anti-corrosion.
Anti-corrosion services for concrete plants and structural steel must ensure that their coatings meet the environmental demands in which the structure lies. Such coatings provide long term protection for structural steel, hence leading to steel reinforcement. Chemical Resistance coating for pits and similar applications

Jun 17, 2016 · Reinforced concrete is everywhere. But unlike plain concrete, which can last for centuries, reinforced concrete can deteriorate in decades as the reinforcing bars succumb to rust. The problem with ...
In a sound concrete the pH value of the cement paste is about 12-13, offering a protection to steel by the formation of a thin layer of bonded and insoluble oxide, which stops the reaction of oxidation. The corrosion is possible with a lower pH of cement paste, in the range of 8 to 9.
Jiangsu Zhongtai Steel Structure Co. Ltd.（ZTSS）is located in the most vigorous Yangtze Delta Area of East China, close to the northern side of Jiangyin Yangtze Highway Bridge, the company covers nearly 1000M riverside of Yangtze and possesses a heavy vertical-faced wharf of 5000 ton.
Galvanic cathodic protection of steel in concrete is a practical way to inhibit rebar corrosion in reinforced concrete structures. For more info contact us!
Modern reinforced concrete can contain varied reinforcing materials made of steel, polymers or alternate composite material in conjunction with rebar or not. Reinforced concrete may also be permanently stressed (concrete in compression, reinforcement in tension), so as to improve the behaviour of the final structure under working loads.

ANTICORROSION PROTECTION OF STEEL AND CONCRETE STRUCTURES We are specialised in the application of anti-corrosion coatings in accordance with ISO 12944 and high technological systems for painting and metallization.
The steel rebar used in concrete strengthens the structure by providing a solid tensile strength concrete normally lacks. When the steel begins to rust and produce pits or holes in its surface, a reduced strength capacity is seen, which negatively affects the structure’s viability.
Even though both the pipe and support are steel, the metallurgical differences can still provide a small potential difference to create a corrosion cell. The corrosion mechanism It is a common misconception that metal-to-metal contact coupled with water entrapment is the major cause of corrosion at these points.
Aug 30, 2019 · The steel rebar used in concrete strengthens the structure by providing a solid tensile strength concrete normally lacks. When the steel begins to rust and produce pits or holes in its surface, a reduced strength capacity is seen, which negatively affects the structure’s viability.
The corrosion of structural steel is an electrochemical process that requires the simultaneous presence of moisture and oxygen. Essentially, the iron in the steel is oxidised to produce rust, which occupies approximately six times the volume of the original material.
TYPES OF CONSTRUCTION TYPE I – This concrete and steel structure, called fire resistive when first built at the turn of the century, is supposed to confine a fire by its construction. This type of construction in which the building elements listed in IBC Table 601 are of non-combustible materials, such as concrete and steel.
make the repairs. While the corrosion of reinforcing steel is not the only cause of structural deficiencies in bridges in the United States, it is a significant contributor, and therefore a matter of major concern (Virmani and Clemena 1998). 1.2 BACKGROUND Until the late 1960s, reinforced concrete bridges performed reasonably well,

Corrosion is not a concern when steel is enclosed by building finishes, coated with a contact-type fireproofing or in contact with concrete. In these cases, the steel does not need to be primed or painted. This covered condition applies to the majority of steel building applications, which leaves only a few special conditions where steel needs to be protected.
