Bridge waterproofing method using fine activated carbon powder

Hereinafter, a bridge waterproofing method using a fine activated carbon powder according to an embodiment of the present invention will be described in detail.

1 schematically shows the construction steps of a bridge waterproofing method according to an embodiment of the present invention.

According to an embodiment of the present invention, there is provided a bridge waterproofing method using a fine activated carbon powder, comprising: forming a primer layer 10 by applying a primer on a concrete top plate; forming a coating film waterproofing material layer 20 by applying a coating film waterproofing material including asphalt, a modifier, a viscosity modifier, a tackifier, and a filler on the primer layer 10; and disposing a protective layer 30 impregnated with asphalt on the coating film waterproofing layer 20 .

As shown in Figure 1, the bridge surface waterproofing method is a step of forming a primer layer 10 on a concrete top plate (C) (S110), applying a coating waterproofing material to form a coating waterproofing material layer 20 (S120) , disposing the protective layer 30 (S130), and laying asphalt on the protective layer 30 to form an asphalt pavement layer (A) (S140).

That is, in one embodiment of the present invention, the bridge surface waterproofing layer 1 can be formed on the concrete top plate C by the bridge surface waterproofing method including the construction step as described above.

The step of forming the primer layer 10 on the concrete top plate (C) (S110) corresponds to the step of forming the primer layer (10) by applying a primer on the concrete top plate (C).

At this time, the primer layer 10 can improve the adhesion between the waterproofing coating layer 20 and the concrete top plate (C). That is, the step (S110) of forming the primer layer 10 on the concrete top plate (C) corresponds to a pre-treatment operation step preceding to construct the bridge waterproofing layer (1) on the concrete top plate (C).

On the other hand, the step of forming the coating film waterproofing material layer 20 by applying the coating film waterproofing material (S120) is applying a coating film waterproofing material comprising asphalt, a modifier, a viscosity modifier, a tackifier, and a filler on the primer layer 10. Corresponds to the step of forming the coating film waterproofing material layer (20).

At this time, the coating film waterproofing material layer 20 may serve as a waterproofing layer capable of preventing foreign substances such as moisture from penetrating into the concrete upper plate (C). Specifically, the coating film waterproofing material layer 20 formed by applying the coating film waterproofing material may serve as a waterproofing layer by implementing a waterproofing function by the composition constituting the coating film waterproofing material.

The coating film waterproofing material according to an embodiment of the present invention may include asphalt as a main component, and may include a modifier, a viscosity modifier, a tackifier, and a filler.

Preferably, the asphalt according to an embodiment of the present invention includes at least one of straight asphalt and blown asphalt, the modifier includes at least one of SBS rubber and EVA resin, and the viscosity modifier is a process oil, and at least one of paraffinic oil, the tackifier includes at least one of natural rosin and a thermoplastic resin, and the filler includes fine activated carbon powder, fine ferronickel slag, and calcium carbonate. .

In addition, the coating film waterproofing material according to an embodiment of the present invention, based on the total weight, 50 to 70% by weight of asphalt, 5 to 15% by weight of the modifier, 5 to 10% by weight of the viscosity modifier, 2 to 5% by weight of a tackifier, and 10 to 20% by weight of a filler.

Preferably, the coating film waterproofing material according to an embodiment of the present invention, based on the total weight, 50 to 70% by weight of straight asphalt, and at least one of blown asphalt, 5 to 15% by weight of SBS rubber, and EVA resin 1 or more, 5 to 10% by weight of process oil, and 1 or more of paraffinic oil, 2 to 5% by weight of natural rosin, and 1 or more of petroleum resin, and 10 to 20% by weight of activated carbon fine powder, ferronickel slag fine powder, and calcium carbonate.

In this case, the filler according to an embodiment of the present invention may include 2 to 8% by weight of the activated carbon fine powder, 2 to 8% by weight of the ferronickel slag fine powder, and 1 to 10% by weight of calcium carbonate.

The composition range of the coating film waterproofing material as described above corresponds to a range in which resistance according to temperature can be improved.

Conventional asphalt is prone to breakage at low temperatures, and there is a problem in that it is vulnerable to temperature changes, such as plastic deformation at high temperatures. The coating film waterproofing material according to an embodiment of the present invention can implement temperature resistance suitable for preventing plastic deformation at low and high temperatures by including the above components and compositions.

The composition range of the coating film waterproofing material as described above corresponds to a range in which the coating film waterproofing material layer 20 having excellent elasticity and waterproofness can be implemented.

Preferably, as 5 to 15% by weight of the modifier is added to the waterproofing coating, the elasticity and waterproofing properties of the coating waterproofing layer 20 may be improved. More specifically, when the modifier is added in an amount of less than 5% by weight, the elasticity and waterproofness of the coating film waterproofing material layer 20 may be reduced, and when it is added in an amount of more than 15% by weight, the coating film waterproofing material layer 20 of The elasticity is excellent, but the workability may be deteriorated.

The composition range of the coating film waterproofing material as described above corresponds to a range capable of improving salt damage resistance and waterproof function.

Preferably, as 2 to 8% by weight of the activated carbon fine powder is added to the waterproofing film, the components constituting the waterproofing film can be adsorbed and uniformly mixed, so that a watertight coating film waterproofing layer 20 can be implemented.

The composition range of the above coating film waterproofing material corresponds to a range that can provide an economical bridge surface waterproofing method.

Preferably, fine activated carbon powder 5 times lighter than calcium carbonate can lower the specific gravity of the coating film waterproofing material, so that when the coating film waterproofing material layer 20 having the same thickness is formed, compared to the coating film waterproofing material to which the activated carbon fine powder is not added The amount of construction can be reduced. For example, to form a waterproofing coating layer 20 having a thickness of 2 millimeters by applying a coating waterproofing material (specific gravity = 1.25 ton/m ^{3 ) to which no activated carbon fine powder is added, 2.5 kg of coating waterproofing material is used, while activated carbon} 2.3 kg of the waterproofing coating material may be used to form the coating waterproofing material layer 20 having a thickness of 2 millimeters by applying the fine powder-added waterproofing material (specific gravity = 1.15 ton/m ^{3 ).}

In addition, when melting to construct the waterproofing coating, the fine activated carbon powder added to the waterproofing coating can prevent the calcium carbonate from sinking down. Accordingly, it is possible to reduce the number of times of cleaning the sunken calcium carbonate in the case of constructing the coating waterproofing material compared to the coating waterproofing material to which the activated carbon fine powder is not added, thereby providing a more economical bridge surface waterproofing method.

As described above, as the coating film waterproofing material according to an embodiment of the present invention utilizes a combination of fine activated carbon powder and fine ferronickel slag powder, physical properties such as tensile performance, shear adhesion performance, and tensile adhesion strength are improved as well as excellent flame resistance It is possible to exert the effect of providing a bridge waterproofing method with decomposition properties.

In one embodiment of the present invention, the activated carbon fine ^{powder may correspond to a powder having a specific surface area of 500 to 900 m 2} /g, a density of 0.35 to 0.5 t/m ³ , and a particle size of 70 to 110 micrometers. That is, as the coating film waterproofing material includes the above fine activated carbon powder, the coating film waterproofing material layer 20 having excellent adsorption power can be formed.

In addition, in an embodiment of the present invention, the ferronickel slag fine ^{powder corresponds to a powder having a fineness of 3,000 to 5,000 cm 2} /g, and has a specific gravity of 2.8 to 3.3 g/cm ^{3 , -0.6 to -0.8} It corresponds to a powder having a loss on ignition of %. Preferably, the fine ferronickel slag powder corresponds to a powder having a fineness of 4,450 to 4,850 cm ^{2 /g.}

Meanwhile, the coating film waterproofing material according to another embodiment of the present invention may include fine activated carbon powder and calcium carbonate as fillers.

That is, the coating film waterproofing material of the present invention may include a filler including a fine activated carbon powder, a fine ferronickel slag powder, and calcium carbonate, or, according to an embodiment of the present invention, a fine activated carbon powder, and a filler including calcium carbonate may include

In this case, by the characteristics of activated carbon as described above, it is possible to adsorb and uniformly mix the components constituting the coating film waterproofing material to form a watertight coating film waterproofing material layer, and to adsorb and remove compounds that cause harmful and unpleasant odors. possible effect can be exerted. In addition, as the relatively light activated carbon fine powder is added to the coating film waterproofing material, the amount of construction of the coating film waterproofing material can be reduced, thereby exhibiting the effect of providing an economical bridge surface waterproofing method.
