Figure 2C illustrates the structure 102 coated with the coating agent 100, according to an embodiment of the present disclosure.The cement / concrete is responsible for constructing buildings / any other structures etc., which plays a major role in development at a large scale. Thus, the structure 102 formed by cementitious material should be protected from various factors, for example, corrosion, permeability, etc., to ensure the longevity of the constructions made by the cementitious material. The coating agent 100 as disclosed may be adapted to coat the structure 102 formed by the cementitious material to ensure longevity of the structure 102, without departing from the scope of the present disclosure.In an embodiment, the coating agent 100 includes, but is not limited to, the solid contact material 202, and a lubricant oil 204, details of which are explained in subsequent paragraphs.In an embodiment, particles of the solid contact material 202 may be sieved by a sieve.

In an embodiment, the sieve may be a 75-micron sieve, without departing from the scope of the present disclosure.In an embodiment, prior to sieving the solid contact material 202, the solid contact material 202 may be adapted to be burnt at a predetermined temperature range for a predefined time duration. In such embodiment, the predetermined temperature range may be between 500 degrees Celsius and 600 degrees Celsius. Further, the predefined time duration ranges between 3 hours and 6 hours, without departing from the scope of the present disclosure.In an embodiment, the lubricant oil 204 may be adapted to be mixed with the sieved solid contact material 202 to form the coating agent 100. In an embodiment, the lubricant oil 204 may be an engine oil, without departing from the scope of he present disclosure. In an embodiment, the sieved solid contact material 202 may be also referred to as the solid contact material 202, without departing from the scope of the present disclosure. Further, the solid contact material 202 and the lubricant oil 204 may be mixed at a ratio of 1:1 to form the coating agent 100 where the coating agent 100 may be coated on the structure 102 formed by the cementitious material.In an embodiment, the structure 102 may include one or more steel bars 104 embedded within the cementitious materials. Further, the coating agent 100 may be coated on the structure 102 and may be adapted to reduce permeability and corrosion in the structure 102.Further, efficiency of the coating agent 100 is also verified experimentally which is explained in subsequent paragraphs.For checking reduction in the permeability, a sample cube of the structure 102 made of the cementitious material is considered. The sample cube may have a predetermined dimension of 150mm.Further, a mixture of the cementitious material is prepared in accordance with IS10262:2019 using a mixture of cement, fine aggregate, coarse aggregates, and water in a predefined proportion. Further details of each component are provided below:For the cement, OPC grade 43 is used for the experiment. The codes referred here are IS: 8112-1989 and IS 4031:1963. The detail of the cement is provided below:Table 1For the fine aggregates, river sand of Zone II is considered. The code for the river sand as used is IS 383:1970. Further, a predefined quantity, i.e., 1000gm of river sand is considered to perform sieve analysis and a predefined quantity of 500 gm is considered to perform a specific gravity test. The detail of the fine aggregates is provided below:Table 2For the coarse aggregates, crushed aggregates having a predetermined dimension of 16mm are considered. The code for the coarse aggregates used is 383:1970. The detail of the coarse aggregates is provided below:Table 3The water used for mixing as well as curing the cement is portable water. Further, the portable water having pH 6.9 is used for curing and mixing the cement. The concentration of water in cement influences many fresh and hardened properties of the cement which include permeability, workability, durability, weathering, water tightness, compressive strength, drying shrinkage, and cracking prospective. Thus, the concentration of water is regulated while mixing the cement to improve the constructability and service life of the cement.Further, the one or more steel bars 104 of the structure 102 may have a predetermined length of 15cm, a predetermined breadth of 15cm, and a predetermined height of 80cm and have a grade of M20.Further, approximately 20 sample cubes are cast, where 10 sample cubes are without the coating agent 100 and remaining 10 sample cubes are coated with the coating agent 100.Once, the sample cubes of the structure 102 are cast, the coating agent 100 is coated on an outer surface of the sample cubes. Particularly, the solid contact material 202 having a predefined weight of 100gms are used with the lubricant oil 204 having a predefined weight of 100ml to coat the outer of the sample cubes.Further, the sample cubes without the coating agent 100 and the sample cubes coated with the coating agent 100 are immersed in the water for 28 days for the curing / curing process. Further, each of the sample cubes is placed in a room temperature for approximately 62 days. Now, after the curing and placing each sample cubes at the room temperature, the permeability checking is carried out for each of the sample cubes as per IS:3085-1965. Particularly, a water pressure of 10kg / cm^2 is applied on each of the sample cubes for approximately 72 hours through a water permeability test apparatus and then, the permeability of each sample cube is recorded. Further, each sample cube is immersed in the water for 73 hours, after approximately 90 days. Thereafter, the water absorption for each sample cube is recorded. Further, the changes in weight of the sample cubes without the coating agent 100 and the sample cubes with the coating agent 100 are observed and provided below:Table 4Thus, the above-mentioned Table 4 indicates a substantial increase in the weight of the sample cubes without the coating agent 100 as compared to the weight of the sample cubes with the coating agent 100. The coating agent 100 prevents the water from percolating inside the structure 102, thus reducing the permeability of the structure 102.Further, for checking corrosion resistance, 6 steel bars are cast, where 3 steel bars are coated with the coating agent 100 and the remaining 3 steel bars are without the coating agent 100. Further, each steel bar is immersed in a saline water with having Sodium Chloride (NaCl) concentration of approximately 3.5%, and subsequently, the curing is carried out for 90 days. After the curing, each steel bar is taken out and further, a half-cell potentiometer test is performed on each steel bar as per ASTM C876-15. After performing the test, 5 readings are recorded for each steel bar. The details of the readings as recorded are given below:Table 5As evident from the Table 5, there is a high risk of corrosion in each steel bar without the coating agent 100 as compared to each steel bar having the coating agent 100. Particularly, the coating agent 100 reduces the permeability of the structure 102 which in turn prevents an ingress of the chloride ions which is responsible for accelerating the rate of corrosion in the structure 102.The present disclosure also relates to a method 300 to form the coating agent 100 as shown in Figure 3. The order in which the method steps are described below is not intended to be construed as a limitation, and any number of the described method steps can be combined in any appropriate order to execute the method 300 or an alternative method.
