Today, concrete structures and parts that have different cement bases are used in the construction of many civil structures in various fields such as building construction, bridge construction, roads and other similar cases. One of the important applications of concrete structures is the construction of storage reservoirs, accumulation, separation, etc. One of the advantages of these reservoirs is the low cost and no need for much knowledge for construction. These reservoirs are generally divided into two categories: above-ground and buried. Above-ground reservoirs are exposed to the effects of weather, damage caused by acid rain, and the effects of mechanical loads. In addition to above-ground reservoirs, buried reservoirs are exposed to internal and external stress from internal and external fluids and soil. According to the mentioned cases, there are problems in the use, maintenance and useful life of this class of reservoirs, which affects its efficiency.
First, we can mention the creation of cracks caused by the shrinkage of concrete in the drying process (hydration), which creates a suitable substrate for the flow of fluid inside the reservoir to the outside. Also, with these cracks in the structure of the reservoir, probably the stored fluids, such as water, which are related to human health, will be contaminated by external fluids that have flowed into the reservoir through the cracks and cause a threat to people’s health. Using the advanced knowledge of composite materials, Farasath Zarfam Company has done several projects regarding the internal and external insulation of these reservoirs, based on the needs of the client, and is ready to cooperate with other respected clients in this field.
Another use of concrete reservoirs is to use them as reservoirs for the accumulation and storage of various materials in various industries. Each industry, according to its needs, begins to build this class of reservoirs with different sizes and shapes. According to the materials inside the concrete reservoir and considering the chemical activity of the concrete itself, the possibility of damage such as corrosion is very high. In order to avoid this problem, Farasath Zarfam Company suggests that before loading the reservoir, it should be reinforced internally with the use of composite coatings in order to prevent this type of damage and consequently increase the working life of the reservoir significantly.
Another group of concrete storage reservoirs have been damaged over the years of their service life and need to be repaired and strengthened. For example, reservoirs that have been exposed to alkaline and acidic fluids, corrosion has even reached the rebars of the reservoir, and any destruction is possible. In addition to corrosive fluids, some reservoirs have been in contact with abrasive materials and have suffered wear over time, and this category also needs to be strengthened and repaired at the same time. The old methods used for repair are very time-consuming and expensive, which require a long deactivation of the reservoir. The methods used in the Farasath Zarfam Company, which is the most advanced method in the world for repairing and increasing the strength of concrete structures, have been used in several successful projects. By using the knowledge available in Farasath Zarfam Company, the ability to provide and perform all types of composite protective and reinforcing coatings for concrete reservoir structures has been provided.
In the end, this company hopes that by relying on our current knowledge and executive power, we will meet the need for insulation, reinforcement and repair of concrete reservoirs of employers in industries such as oil, gas and petrochemical, and metal industries such as copper, iron and aluminum, cement, etc.
