The present invention relates to a composition for permeable structures capable of sliding plants, such as moss and eggs, on the surface, and a method for producing a structure using the same, and more particularly, potted plants capable of sliding surfaces, such as moss, eggs, and papery plants, The present invention relates to a composition capable of producing permeable structures such as accompaniment, artificial stone, landscape stone, landscape sculptures, landscape blocks, and decorative stones for aquariums, and a method for producing a permeable structure using the composition.

In the case where the structure of permeability has been used in the past, there are permeable roads, pavements, and permeable vegetation block structures, but there is no case in which the permeable structure is used for pollen, head, landscaping, and artificial stone.

In general, it is known that there are three important conditions as a soil environment for plants to grow smoothly, which is 50% solids, 25% liquid, and 25% gas. Among them, the solid is soil, the liquid is the water content of the soil, and the gas is the soil breathability.

These three important conditions are also necessary in pots, which are plants for planting plants. However, plastic pots, ceramics pots, and pots manufactured by mixing resins and inorganic fillers, which are generally known as marbles, have a disadvantage of very poor breathability. In some pots, the structure is breathable, but the pots are on the market, but they are not robust and show no satisfactory performance in permeability and breathability. It is impossible to attach moss and paper plants.

Therefore, these ceramic, plastic, and marble pots have very poor ventilation, which plays a very important role in the plant growth environment. Therefore, the roots of the plants may rot and die during long-term cultivation. It acts as a cause of inhibiting plant growth, and in the case of Onggi pot, there is a disadvantage that it is not robust and not enough breathability.

The present inventors have proposed the present invention as a result of repeated studies and experiments to solve the above shortcomings, the present invention gives moisture to the plant roots, as well as moisture retention, drainage, breathability is an important factor for plant growth At the same time, plant can be planted in the inner container, and moss, turbulence, ground cover plants can be grown on the surface, and it can be used as a stone at the same time as a potted stone and artificial stone, head, and landscape stone.

Hereinafter, the present invention will be described in more detail.

The present invention relates to a composition for producing a flower pot, accompaniment, artificial stone, landscaping stone, landscaping sculptures, landscaping blocks, decorative stones for aquariums, and the like, and the following description will mainly be described using a flower pot.

The present invention is to provide a breathable, moisturizing, drainage to the pot at the same time to plant the flowers inside the pot and to grow the plants of the paper species do not require much turbulence, moss, and soil outside the pot. That is, research on the method of manufacturing a flower pot with a structure that allows air to pass through the inside of the flower pot and the outside of the flower pot and leads to continuous voids, and has a water permeability, has made the flower pot into a water permeable structure, thereby providing a breathable function to the flower pot. It provides moisturizing function and drainage function at the same time, and gives the plant outside and the upper edge of the pot with the function of stone cropping, which is a method of attaching the plant to the stone. Likewise, it has developed a pollen, moisture permeability, and breathable form because of its very strong and continuous porosity.

Materials for producing such pots include cement, fine aggregate, slag powder, calcium sulfur aluminate cement, anhydrous gypsum, high performance water reducing agent and the like.

The cement may be used singly or in combination of general port cement, white port cement, slag cement. These cements play the same role as adhesives for adhering aggregates, and if the content is less than 30% by weight, the product is applied to water permeability such as flowerpots and heads, artificial stones, landscaping stones, landscaping sculptures, landscaping blocks, and decorative stones for aquariums. There is a problem in the durability, and if it exceeds 45% by weight, there is a problem in forming the porosity due to the increase in cement fine powder, it is added in a ratio of 30 to 45% by weight.

The fine aggregate may be used alone or in combination with the selected particle size volcanic stone, silica sand, lightweight aggregate. In the case of the fine aggregate, in order to give a continuous porosity between 20 and 40%, the average particle size is more preferably between 1 and 10 mm, and may be partially removed and additionally added according to the thickness, shape, and function of the permeable powder to be produced. Can be. These fine aggregates are present between the cement adhesives to form permeable voids and act as fillers. If the content is less than 50% by weight, there is a problem in forming sufficient permeable voids. Due to the problem of durability of the manufactured product, it is added at a ratio of 50 to 63% by weight.

The slag powder plays a role of long-term durability enhancement, if the content is less than 1% by weight, there is a problem in generating long-term durability effect, when the content exceeds 5% by weight, there is a problem that the water / cement ratio is increased, 1 ~ 5% by weight Add in proportion.

The calcium sulfur aluminate cement plays a role of crack suppression and dry shrinkage reduction, if the content is less than 3% by weight, there is a problem that the shrinkage reduction efficiency is lowered, and if it exceeds 5% by weight, it may cause cracking due to overexpansion. There is a problem and it is added at a rate of 3 to 5% by weight.

The anhydrous gypsum reacts with calcium sulfur aluminate cement to play a role of crack suppression. If the content is less than 2% by weight, there is a problem of less effect of crack suppression, and if it exceeds 5% by weight, there is a problem of excessive expansion and durability deterioration. Therefore, it is added in a ratio of 2 to 5% by weight.

The high performance reducing agent may be used alone or in combination of polycarboxylate-based, lignin-based, naphthalene-based, melamine-based. The high performance water reducing agent reduces water / cement ratio to enhance the durability of products using water permeability and facilitates workability when mixing materials. When the content is less than 0.05% by weight, the water / cement ratio is secured to the required level. If there is a problem, if the content exceeds 1% by weight, the raw material cost rises and there is a problem that a material separation phenomenon occurs due to excessive water-reducing effect, and is added at a ratio of 0.05 to 1% by weight.

In addition to the above components, pigments of various desired colors may be further added, including black pigments and red pigments. It is more preferable to add the pigment added at the ratio of 1 to 5 weight% at this time.

Preferred examples of the method for producing a structure using the materials having the composition ratios described above can be performed in the same order as shown in FIG.

That is, to prepare a water-permeable structure, first, the composition is mixed in proportion. It is preferable to mix the material as described above more homogeneously in the ratio as described above.

In addition, water is added to the mixed mixture. At this time, the ratio of water / cement (weight ratio) is preferably 0.25 to 0.40. If it is less than 0.25, the workability is considerably deteriorated, which causes problems in strength expression and durability. This is because the continuous porosity, which is a structure through which the outer surface can pass, is not generated and a problem of deterioration in durability occurs.

In addition, the mixing step is followed by sufficient mixing. It is preferable to use a mixer, and the said mixing can be performed using a mixer normally used.

In addition, the mixed material is subjected to a step of putting in the mold prepared in advance. The mold is prepared in advance in the shape and size of the desired structure, such as potted plant, head, artificial stone, landscape stone, landscape sculpture, landscape block, decorative stone for aquarium.

In addition, after the mold is put in, it undergoes a curing period of about 3 to 7 days and undergoes demolding. The curing period is preferably about 3 to 7 days, but the reason is that when the inorganic cement is cured at about 20 ° C. for more than 3 days, 40% or more of compressive strength is expressed. Curing for 5 days can shorten the manufacturing period and secure durability.

In addition, after demolding, a neutralization treatment is performed. Planting plants without performing the neutralization treatment has a negative effect on the growth of plants due to the excessive alkali component of cement-based binders. In the present invention, a step of neutralization treatment is performed to prevent this, and the neutralization treatment is more preferably performed using an aqueous ammonium diphosphate solution.

According to the present invention as described above, at the same time as the function of the general potted plants, such as planting plants in the inner space and high continuous porosity is ensured more water permeability, breathability, water retention in the potted plant, and at the top and outside of the potted plant Turbulent, moss, papery plant roots can be easily slid to obtain multifunctional flower pots that can simultaneously perform the functions of stone-loading stones, and also include heads, artificial stones, landscaping stones, landscaping sculptures, landscaping blocks, and aquarium stones There is also an effect that can be utilized.

Embodiments according to the present invention can be modified in many different forms, the scope of the present invention is not limited to the embodiments described below.

<Examples>

After homogeneously mixing the materials in the ratio shown in Table 1 below, water was added so as to have a water / cement ratio as shown in Table 1 below, followed by mixing sufficiently using a mixer. After mixing, the mixture was put into a potted mold having an outer diameter of 200 mm, an inner diameter of 150 mm, and a height of 130 mm, then cured for 5 days, and demolded, and neutralized using an aqueous ammonium diphosphate solution to prepare a pot.

Physical properties such as compressive strength (5 days) and continuous porosity of the prepared pollen were carried out and the results are shown in Table 2 below. In this case, the physical property test was carried out by the KSF 2405 concrete compressive strength test method for the compressive strength, and the porosity test was carried out by a measuring method according to the Japanese Concrete Institute (porosity test method (draft) of Poros concrete). Porosity calculation was performed by the following equation.

In the above formula, W1 is the weight of the test body, W2 is the weight of the test body, and V1 is the volume of the test body.

Inventive examples 1 and 2 satisfying the conditions of the present invention among the pots manufactured as described above have a structure that allows air to pass through without blocking the inside and outside of the pot, and leads to continuous pores, which is permeable to the pot. It was given the moisturizing function and drainage function at the same time.

In addition, as can be seen in Table 2, in the case of Inventive Examples 1 and 2, the compressive strength is 10N / mm ² or more, the porosity is 30% or more, so that the permeability through securing the durability and porosity as a plant pot to be pursued in the present invention Castle, breathability and water retention could be given to pots, heads, artificial stones, landscaping stones, landscaping sculptures, landscaping blocks, and aquarium decorative stones. Compressive strength of 10N / mm ² or more can be seen to secure a very solid level of durability compared to the general flower pot and may vary in durability depending on the type of pot, but if the compressive strength of the level of the invention examples 1 and 2 above the pot and water permeability described above It is evaluated at the level of durability that has no problem in constructing the structure.

On the contrary, in Comparative Example 1, the compressive strength, which is the index of durability, was very high due to the large number of cement components serving as binders, but the porosity was too low due to the excessive amount of finely divided cement components, thus departing from the spirit of the present invention. In Comparative Example 2, the porosity was excellent because the cement component serving as a binder was too small, but the compressive strength as a flower pot was low, and the durability was poor.

Plants were actually planted in the pots of Inventive Example 1 as shown in the photograph of FIG. 2, but the outer side of the pots and the upper edges of the pots were easily slid of the plant roots, thereby making it possible to attach the plants to the stones.

On the other hand, using the same compounding ratio materials as in Inventive Example 1, water / cement ratio was 0.20 and 0.45, respectively, to prepare the same pot. The strength and porosity of the manufactured pollen were investigated. As a result, when the water / cement ratio was 0.20, the workability was remarkably deteriorated, resulting in problems of strength expression and durability, and when the water / cement ratio was 0.45, There was a problem in that durability was not generated without continuous porosity, which is a structure that allows the inner and outer surfaces to pass.
