In general, the sidewalk block can be attributed to the continuous arrangement of sidewalks in India, starting from the boundary between the roadway and the sidewalk. In consideration of economic problems and mass production, these sidewalk blocks are mainly made of concrete molded products to a predetermined size and shape.

Most of the sidewalk blocks as described above are formed by stone or cement according to the place and use, and these sidewalk blocks are formed in various shapes and thicknesses, and one sidewalk block and another neighboring sidewalk block are formed. It is installed on the sidewalk by the method of being connected to each other continuously.

On the other hand, the sidewalk blocks as described above are variously installed in India, such as parks and apartment complexes, since the sidewalk blocks are arranged in India on the basis of a boundary line separating the road and the sidewalk. The sidewalk block according to the prior art focuses on the convenience of pedestrians, but recently, the convenience of pedestrians as well as the aesthetics of streets, parks, and apartment complexes are considered.

As described above, the sidewalk blocks are sequentially arranged to face each other in order to pave the floors of sidewalks, sidewalks, housing complexes, plazas, parks, parking lots, etc. in consideration of urban aesthetics and ease of walking in urban planning. Some granite or marble blocks are used, but most of them are blocks that are molded from concrete materials.

In particular, in recent years, a variety of colors, shapes, or shapes are modified to pursue aesthetics or to add a function such as anti-slip or far-infrared emission has been gradually expanding the range of use.

As mentioned above, in recent years, as apartments such as apartments or promenades have been gradually advanced, many functional blocks are used for sidewalks, parks, and promenades in the complex. There is no situation.

The present invention has been made to solve all the problems of the prior art, the block is formed of a structure consisting of a base layer and a surface layer, but the surface layer by forming a fragrance capsule formed with a fine microcapsule containing the fragrance when passing pedestrians and vehicles It is to provide an eco-friendly fragrance block that provides a pleasant environment by releasing a pleasant fragrance like natural fragrance by bursting the fragrance capsule by friction.

In addition, the technology according to the present invention is to form a block structure consisting of a base layer and a surface layer to reduce the amount of sand used by using the recycled aggregate in the base layer.

Figure 2 is a flow chart for explaining the manufacturing process of the eco-friendly fragrance block of the present invention.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the eco-friendly fragrance block of the present invention.

1 is a perspective view of a partially cut into the eco-friendly fragrance block according to an embodiment of the present invention.

As shown in FIG. 1, the eco-friendly fragrance block of the present invention is located at least in two upper and lower layers, for example, the base layer 10 and the upper portion in consideration of moldability and the degree of friction with the fragrance capsule. It may be made of two or more layers of the surface layer 20 to be exposed, the blending component and the ratio of the base layer 10 and the surface layer 20 is made differently as will be described later.

On the other hand, in the configuration of the eco-friendly fragrance block according to the present invention as described above, the base layer 10 is composed of cement, sand, recycled aggregate, water and admixture in a predetermined ratio, but the sand 220 to 240 weight by weight based on 100 parts by weight of cement It is mixed in a proportion of 190 to 210 parts by weight of recycled aggregate, 15 to 30 parts by weight of water and 0.2 to 0.6 parts by weight of admixture.

And, in the composition of the eco-friendly fragrance block according to the present invention, the surface layer 20 is composed of a back cement, white stone powder (# 14-24), PS Ball, sand, water, admixtures and fragrance capsules at a predetermined ratio. 250 to 270 parts by weight of white stone powder (# 14-24), 90 to 95 parts by weight of PS Ball, 35 to 45 parts by weight of sand, 24 to 30.67 parts by weight of water, 0.4 to 1.33 parts by weight of admixture and fragrance capsule The composition is mixed at a ratio of 0.27 to 0.67 parts by weight.

Table 1 and Table 2 below shows the ingredients of each of the base layer 10 and the surface layer 20 in the eco-friendly fragrance block of the present invention, Table 1 and Table 2 in the base layer 10 and the surface layer ( 20 shows the actual mixing ratio. At this time, the water and admixtures of Table 1 represent the weight percent, respectively, and the cement and the water and admixture capsules of Table 2, respectively, represent the weight percent of the cement.

As can be seen from Tables 1 to 4, when the curing is completed, the base layer 10, which is located on the floor and does not affect the aesthetics, uses general cement instead of back cement. Large amounts of recycled aggregates are used to reduce usage. In addition, sand is used. The base layer 10 may be formed in a range of 1/3 or more, more preferably 1/2 to 5/6 from the bottom surface based on the bottom surface of the block.

On the other hand, in the case of the surface layer 20 in consideration of the recent application of a variety of colors to the surface of the block or to form the unevenness or shape on the surface of the cement instead of using a relatively good aesthetic and formability back cement Also, instead of circulating aggregate, Baekseok powder (# 13-24) and PS Ball are used.

The right column in Table 1 to Table 4 shows the weight ratio of water, admixture and fragrance block to the back cement. Admixture is used for the purpose of improving the properties before and after hardening of concrete. In addition to the aggregate, the material that is intentionally added to the concrete is used so that its amount does not affect the volume calculation of the concrete.

In addition, the circulation aggregate is used only for the base layer 10, and considering the thickness of the block, it is preferable to use the residual circulation aggregate having a diameter of 5 mm to 13 mm.

Next, the fragrance capsule is a microcapsule, which has a hole in the outer wall of the capsule, and has a sustained-release microcapsule, which is broken by friction with the sustained-release microcapsule. Destructive microcapsules are used. These fragrance capsules can preserve the fragrance in the capsule for more than one year without breaking the capsule. Therefore, the fragrance capsule is gradually destroyed and disintegrated from the surface exposed to the landfill by friction during walking or driving. Can give off incense. The fragrance included in the fragrance capsule may be natural, such as phytoncide, aroma or various fruit flavors.

In addition, PS Ball (Precious Slag Ball) refers to the weathered slag aggregate having a particle size of 1 to 2 mm, which is contained only in the surface layer to impart the anti-slip effect and the friction to the fragrance capsule. Here, the wind-chain slag is collectively treated with a technique called slat atomization technology (SAT) which rapidly cools molten steel slag and converts it into a stable molecular structure.

2 is a flowchart illustrating a manufacturing process of an eco-friendly fragrance block of the present invention.

As shown in FIG. 2, first, in step S10, the collected waste concrete is pulverized to have a particle size distribution of 5 to 13 mm or less and a residual circulation aggregate is removed.

Next, in step S20, the remaining recycled aggregate and the cement, sand, water, and admixture thus removed are added to the base mixer according to the mixing ratio set in Table 1, followed by sufficient stirring. At the same time, in step S30, the back cement, white stone powder (# 14-24), PS Ball, sand, water, admixtures and fragrance capsules are added to the surface mixer according to the mixing ratio set in Table 2, and then stirred sufficiently. Dilute the amount of fragrance capsules to water, add them to the water and then add them to the surface mixer.

Then, in step S40, after filling the mixing mixture, that is, the base mixture in the mold of the vibration compactor formed in the block shape in a predetermined shape in the step S40 by applying a vibration for a predetermined time to improve the density and flatten the surface.

In the state as described above, in step S50 in step S40 immediately after step S40 or after a predetermined time elapses before the base layer 10 is cured, the blend, that is, the surface layer blend, is stirred by a predetermined amount on the base of the mold of the vibration compactor. Vibration is applied for a predetermined time after filling to improve the bonding strength and density with the base layer and to make the surface flat.

Finally, in step S60, the block molding is separated from the mold, and then transferred to a drying chamber for curing (drying).

Of course, after curing, a finishing process, such as spraying colored paint, may be added.

Eco-friendly fragrance block of the present invention is not limited to the above-described embodiment can be carried out in a variety of modifications within the scope allowed by the technical idea of the present invention.
