Concrete basins are widely used for various purposes such as sedimentation, aeration, etc. in industries. Concrete basins are made of a combination of cement-based concrete and iron bars. Cement, as the base of various structures, has a lower price and easier processing than other materials. However, due to its chemical structure, cement undergoes rapid changes and decreases in its properties when it reacts with other materials.
For example, in the vicinity of alkaline and acidic fluids, cement reacts with these substances and, in other words, undergoes corrosion. With regard to the scientific support and numerous work records in this field, Farasath Zarfam Company offers various coating solutions such as composite to the respected employers. With the corrosion over time and the fall of the concrete surface, the corrosive fluid reached the reinforcing bars of the reservoir, which leads to the threat of structural strength and the possibility of sudden destruction of the basin and the spread of dangerous fluid in the environment.
Also, the reactivity of metal rebar by being in the vicinity of acidic alkaline corrosive fluids causes severe corrosion, which requires very expensive and time-consuming traditional repairs, during which the basin must be taken out of service. This type of destruction consists of the destruction of concrete and rebar, which is repaired by using modern methods.
The mentioned problems lead to numerous financial, time and environmental damages to the users. Therefore, Farasath Zarfam Company, using the state-of-the-art knowledge, has decided to use composite materials that include polymer bases and reinforcing fibers to solve the above problem. As mentioned, these types of basins are in the vicinity of acidic and alkaline fluids, so when choosing the type of polymer base to be used, a polymer will be selected that can withstand the acidity (PH) of the desired fluid and also has a suitable adhesion to the concrete surface.
Besides, temperature conditions are also very effective in determining the polymer resin. In addition to the anti-corrosion polymer base, long and felt-like fibers from materials such as glass, carbon, kevlar, etc. are used to strengthen the base and the entire composite. The selection of fibers is also based on the acidity and alkalinity of the working environment. In general, the composite is used for the two purposes: preventing corrosion and strengthening the surfaces against incoming loads. With the use of composite, concrete reservoirs exposed to acid and base will be protected from damage to a great extent, and according to the design of the repair composite, its mechanical strength will also be significantly improved.
Increasing the service life and significantly reducing the total repair time and cost of this category of basins are other advantages of using the surface coating with composite materials of Farasath Zarfam Company. With its operational and know-how, Farasath Zarfam Company is always ready to provide operations and advice on repairing concrete basins in the shortest possible time.
