Description

Permeable sidewalk block using eco-friendly materials {PERMEABLE SIDEWALK BLOCK USING ENVIRONMENT-FRIENDLY MATERIAL}

The present invention relates to a permeable sidewalk block using an environmentally friendly material that can be effectively permeated with water, and more particularly, by using the aggregate having a certain particle diameter to have a constant porosity to improve the permeability effect and at the same time natural loess stone And it relates to a permeable sidewalk block using an environmentally friendly material that can reduce the whitening phenomenon of the color using the dolseok powder.

Generally, parks and roads have various forms of sidewalks for people to walk safely. Such sidewalks are manufactured in various forms so that pedestrians can walk more comfortably and safely. For example, cement, asphalt, urethane, etc. are poured directly onto the ground to form sidewalks, or concrete or synthetic resins are used. Formed sidewalk blocks are manufactured by forming the sidewalk blocks flat on the ground to form sidewalks.

However, when guiding cement, asphalt, urethane, etc. directly to the ground to form sidewalks, the surface is integrally formed and structurally stable, but the form and color are monotonous. In addition, the water is not permeable at all, causing a lot of sewage.

Therefore, recently installed India has been gradually increasing the production of a variety of patterns and colors while at the same time using the sidewalk blocks to ensure permeability. However, the pigment added to express the color on the sidewalk block, the whitening phenomenon of the color due to sunlight or friction is rapidly progressed, there is a problem that is not visually impaired.

The present invention has been made in order to solve the conventional problems as described above, the object of the present invention, by using an aggregate having a certain particle size to exhibit a certain void, it is possible to improve the permeability effect, natural loess and mudstone It can reduce the whitening phenomenon of the color using powder, and relates to a permeable sidewalk block using environmentally friendly materials capable of far-infrared emission, soundproofing, and humidity control.

The mixing is to maintain the voids in the finishing layer 13 at 5-8%. Here, if the particle size of the fine aggregate is less than 2.5mm, the porosity is significantly reduced and no permeability is achieved, and when the particle size exceeds 4.5mm, the surface of the finishing layer 13 is not smooth and is formed unevenly. That is, the use of the particle size of the fine aggregate is 2.5 ~ 4.5mm is to make the surface uniformly while ensuring the permeability of the finishing layer (13).

The binder is environmentally friendly and natural ocherite powder, mokseok powder, steel slag and slaked lime are mixed to ensure sufficient bonding strength, natural ocher, mokseok, steel slag and slaked lime 1 ~ 1.5: 1 ~ 1.5: 0.8 ~ 1: It is mixed by the weight ratio of 0.3-0.5. At this time, it is preferable to use the mokseok, the particle size of 100 ~ 150mesh gray wood and red mokseok in a weight ratio of 1: 1.5. In the present embodiment, it is described that the mixture of the lumber stone and the red lumber stone in a certain ratio, but may be used by mixing any one selected from the lumber stone or red tiger stone in the binder.

In addition, when curing the finishing layer 13, the mixing of the natural ocherite powder and the thick wood powder to the binder when the curing of the finishing layer 13, the finishing layer 13 by the natural ocherite powder and the neck of the stone powder as it is This is to reduce the whitening phenomenon of the color by giving a color. In addition, far-infrared rays and anions are generated from the natural ocherite powder and the mudstone powder, so that the permeable ocher block 10 becomes more environmentally friendly.

On the other hand, the coarse aggregate of the base layer 11 and the fine aggregate of the finishing layer 13, at least one selected from among the waste materials, waste tiles, waste tiles, waste panels, which are construction waste materials, the specific gravity is 2.4 It is preferable that it is to 2.6. In addition, the water absorption is preferably 10.0% or less, and the wear rate is preferably 22% or less.

The following Table 1 and Table 2 show the chemical composition of red wood tiger and lumber stone, CaO component of red wood tiger reacts with hydrated lime to increase the strength of the finishing layer 13, the silica-based component of the wood lumber By increasing the viscosity of the binder to prevent material separation of the base layer 11 and the finishing layer 13, promotes initial hydration.

According to the present embodiment, the ratio of chemical composition of red mudstone is as shown in Table 1 below.

In addition, when water is permeated by the natural ocherite powder and the mudstone powder, adsorption and filtering of contaminants are performed, so that water that has passed through the pitcher footpath block 10 is naturally purified.

In addition, natural ocherite powder and mudstone powder adsorb and decompose contaminants and heavy metals.

In addition, since the permeable sidewalk block 10 has a moisturizing effect containing water by the pores of the base layer 11 and the finishing layer 13, it also shows the effect of maintaining humidity.

~ 19.4 N / mm

The strength of the sidewalk block was secured, and the flexural strength was also improved compared to the standard. In addition, the coefficient of permeability was 10 to 20 times higher than that of ordinary yellow blocks and concrete blocks. Heavy metal elution was not detected in all of the present examples, ordinary ocher blocks and concrete blocks, and the far-infrared wavelength was also 5 μm to 15 μm, which is contained in large amounts in ocher and mica stones, which are the most beneficial wavelengths for the human body. Penetrate up to 3 ~ 4cm) to promote cells to increase body temperature. Moisture-absorbing rate was found that the specimen according to this embodiment is superior to the general ocher block or concrete block.

 As a result of measuring the surface release amount of whitening occurrence, the surface area of calcium hydroxide was measured in the state exposed to the surface for more than 6 months, and as shown in [Table 3], this embodiment showed 8 ~ 10 times more than whitening phenomenon compared to Comparative Examples 1,2. It has been shown to slow down or prevent.

This is because the silica-based component of SiO ₂ , which contains a large amount of bran, forms calcium calcium hydrate (Calcium-Silicate-Hydrate (CSH)) by combining calcium ions with silica by a pozzolanic reaction, and this type of hydrate is amorphous. It is formed in a solution mixture of silica and calcium hydroxide. These amorphous silicas from the thirsty react with more than 95% of calcium hydroxide and reduce the amount of calcium hydroxide coming out to suppress or delay whitening.

This mechanism is very important because it can work efficiently depending on the dispersion state of silica particles, and a large amount of water reducing agent is required to overcome the influence of surface forces and to fully fill the solid particles. In addition to the mixing, the proper order of feeding the materials into the mixer is also very important.

On the other hand, the permeable block consisting of the base layer and the finishing layer, as in the present embodiment, can be used as a building interior material by manufacturing in a panel form, when manufacturing the building interior material to increase the strength of the base layer and the finishing layer and reduce the porosity The amount of the steelmaking slag cement used in the base layer and the binder used in the finishing layer may be increased by 10 to 20% so as to be blended. Then, the porosity of the base layer and the finishing layer is reduced to 3-4% to have sufficient strength as a building interior material.

What has been described above is only one embodiment for carrying out the present invention, and the present invention is not limited to the above-described embodiment, and the present invention is made without departing from the gist of the present invention as claimed in the following claims. Anyone with ordinary knowledge in this field will have the technical spirit of the present invention to the extent that various modifications can be made.
