BACKGROUND OF THE INVENTION 1. Field of the Invention < RTI ID = 0.0 > [2] < / RTI >

Concrete products that are used in contact with soil or water such as conventional shore blocks, artificial fish candles, sofa blocks, bench plumes, and tetrapods have been evaluated as the main performance indexes of compressive strength and durability. However, It is difficult to call the conventional concrete products as "environmentally friendly ".

In recent years, interest in waterside and aquatic environments has increased, and it has been urgently required to develop a technology for conserving and activating waterfront and aquatic ecosystems in producing concrete products by giving great value to environment-friendly ones. Korean Patent No. 10-0944238 and the like exist as a prior art which expresses environmental friendliness, but such prior art does not have a substantial environment-friendly property on the waterside and aquatic ecosystem.

Korean Patent Registration No. 10-0944238 (issued February 22, 2010).

The present invention has been developed in order to meet the desperately needed needs in the above technical field and is a concrete product used in contact with water such as a shore block, A concrete composition and an environmentally friendly concrete product manufactured using the same.

 In order to achieve the above object, the present invention provides a concrete composition comprising a binder, an aggregate, and a cementitious binder, wherein the byproduct of agricultural processing comprises not less than 0.5 parts by weight and not more than 5 parts by weight Or less. Preferably, the by-product of agricultural processing is contained in an amount of 1 to 5 parts by weight based on 100 parts by weight of the binder, and more preferably 3 to 5 parts by weight with respect to 100 parts by weight of the binder .

In the present invention as described above, the agricultural processing by-products are powdery residues left after the processing of one or more raw materials selected from the group consisting of corn, sesame, soybean, cashew nut, sugar cane, kapok, cotton, rice and barley . At this time, it is preferable that the maximum particle of the powder of the agricultural processing by-product is 30 mu m or less.

In particular, the agricultural processing by-products may be lysine CMS, which is a fermentation by-product of sugar cane, or soybean extract powder made from residue left after processing soybean.

As another means for achieving the above object, the present invention provides a concrete product made of the concrete composition of the present invention. The concrete product of the present invention can be applied with a mixed solution of soybean extract powder on the surface thereof after the concrete is cured. When the weight of water is 100 parts by weight, the soybean extract powder is mixed with 0.1 part by weight to 1 part by weight It is mixed with water as part.

In the case of the concrete product according to the present invention, the growth promoting material contained in the agricultural processing by-products mixed in the concrete composition of the concrete product and the soybean extract powder mixed on the surface of the product is eluted, It is active and grows briskly. That is, according to the present invention, the effect of activating and activating the growth of waterside and aquatic plants, the concentration of aquatic organisms and supplying nutrients can be exerted.

Therefore, according to the present invention, when a concrete product used in contact with water, such as a revetment block, an artificial fish supple, a sofa block, etc., is produced, water and an underwater ecosystem can be preserved and activated.

Hereinafter, preferred embodiments of the present invention will be described. However, this is described as an embodiment, and the technical idea, core structure, and operation of the present invention are not limited thereby.

In the present invention, in the production of a concrete composition for producing concrete products and a concrete product using the same, agricultural processing by-products containing a large amount of nutrients (amino acids, proteins, enzymes, minerals, etc.) necessary for water- . Specifically, the concrete composition according to the present invention comprises the binding water, the aggregate and the cement based binder, and when the binder is 100 parts by weight, the agricultural processing byproduct is added in an amount of 0.5 to 5 parts by weight, To 5 parts by weight, more preferably 3 parts by weight or more and 5 parts by weight or less.

In the present invention, the agricultural processing by-products contained in the concrete composition for accelerating biological growth may be obtained by treating one or more raw materials selected from the group consisting of corn, sesame, soybean, cashew nut, sugar cane, Which is obtained by processing (for example, residues left after the liquid is extracted while making oil, alcohol, etc.) by pressing or fermenting. That is, the agricultural processing by-products used in the present invention are obtained by squeezing or fermenting the above-mentioned raw materials, and then making the residue left after the processing such as making oil, alcohol or the like. At this time, it is preferable that the powder of the by-product of agricultural and marine processing has a maximum particle size of 30 탆 or less.

The components contained in the residue left after processing such as sugarcane and soybean fermentation and squeezing are useful for biological growth such as rooting of plants, promotion of growth, promotion of growth during lack of sunshine, . Such post-processing residue still contains a variety of nutrients necessary for biological growth, so that it exhibits the intended performance of the present invention, but is relatively inexpensive relative to the raw material. Accordingly, when the byproduct of agricultural processing corresponding to the residue after processing is used, the concrete composition according to the present invention can exhibit a desired performance, while greatly reducing the cost, thereby improving the economical efficiency.

As the by-product of agricultural processing as above, lysine CMS (Condensed Molasses Solubles), which is a fermentation by-product of sugar cane, is the most preferable. When lysine CMS is produced as fermentation byproducts in sugarcane fermentation, the lysine CMS generally contains 41 to 43% by weight of crude protein, 10 to 13% by weight of monocotyledonous nitrogenous compounds, 15 to 30% by weight of silkworm nitrogenous compounds, And a chemical composition containing 15 to 30 wt% of nitrogen water. In the present invention, such lysine CMS can be used as a by-product of agricultural processing. One of the preferable agricultural byproducts used in the present invention is a "soybean extract powder" made by drying and pulverizing the residue left after processing the soybean.

In the concrete composition of the present invention, the agricultural processing by-product, which is a bio-growth promoting material, is contained in an amount of 0.5 to 5 parts by weight based on 100 parts by weight of the binder. Preferably, the by-product of agricultural processing is contained in an amount of 1 to 5 parts by weight based on 100 parts by weight of the binder, more preferably 3 to 5 parts by weight with respect to 100 parts by weight of the binder . This makes it possible for plants or aquatic plants to grow easily around the concrete product itself or on its own, and to exert an advantageous effect of easily attracting fish or aquatic life to concrete products.

If the content of byproducts of agricultural processing is less than 0.5 part by weight, various nutrients necessary for biological growth will not be sufficient, and the plant growth promoting effect, the fish attracting effect and the activation effect of aquatic organisms can not be expected at all. The processing by-products must be contained in an amount of 0.5 part by weight or more based on 100 parts by weight of the binder. In particular, when the byproduct of agricultural processing is contained in an amount of 1 part by weight or more based on 100 parts by weight of the binder, the concrete product made of the concrete composition exhibits more excellent compression strength, When the composition is contained in an amount of 3 parts by weight or more based on 100 parts by weight of the binder, further improved plant growth promoting effect is exhibited.

 On the other hand, when the content of agricultural processing by-products exceeds 5 parts by weight with respect to 100 parts by weight of the binder, there arises a problem of lack of strength and durability of the concrete product made of the concrete composition, There is a problem that the odor becomes excessive.

On the other hand, the concrete product according to the present invention is manufactured from the concrete composition of the present invention as described above. After the concrete is cured, a mixture of soybean extract powder is applied to the surface of the concrete product. The soybean-extracted powder mixture is a mixture of soybean-extracted powder made of residual residue after processing soybean with water, and when the weight of water is 100 parts by weight, soybean extract powder is mixed with 0.1 part by weight to 1 part by weight of water . Thus, the soybean extract powder mixture is applied to the surface of the finished concrete product, dried, and finally produced as a concrete product.

Hereinafter, the present invention will be described in more detail by way of examples. It is to be understood, however, that the following examples are provided for illustrative purposes only, and are not intended to limit the scope and spirit of the present invention.

≪ Examples 1 to 9 >

In order to test the strength of the environmentally friendly concrete for bio-growth promotion in the present invention, each composition component was blended so as to have the composition as shown in Table 1, and then put into a mold for vibration molding to prepare a cylindrical concrete specimen having a size of? 100 × h 200 mm Respectively. In the embodiment of the present invention, the lysine CMS or the soybean extract powder as a by-product of agricultural processing is used alone or in combination of two, and the maximum particle size of these agricultural processing by-products is 30 탆. Lysine CMS was purchased from the market, and soybean extract powder was prepared by fermenting soybeans.

As set forth in Table 1 above, lysine CMS was used as the by-product of agricultural processing in Examples 1 and 6, and soybean extract powder was used as the by-product of agricultural processing in Examples 2 and 7. In the case of Examples 3 to 5 and Examples 8 and 9, lysine CMS and soybean extract powder were both used as agricultural byproducts. In the case of Examples 8 and 9 in particular, (Example 8), 100 parts by weight of soybean extract powder was mixed with 100 parts by weight of water (Example 9) to prepare a soybean extract powder mixture And then dried.

In the case of the comparative example, except that lysine CMS and soybean extract powder were not mixed into the concrete composition at all and the soybean extract powder mixture was not applied to the surface, the concrete specimen was prepared in the same manner as in Example 1 Respectively.

<Evaluation of compressive strength of concrete specimen>

Table 2 shows the results of measuring the compressive strength of the concrete specimens of Examples 1 to 9 and Comparative Examples. For example, the standard for the compressive strength of concrete shore blocks is EN745. Blocks, tiles, and panel materials, specimen size 100 × 100 × 100mm, type 1 20.58 N / mm ² (part above water surface of river or sea) or 2 kinds 23.52 N / mm ² However, if considering the use of the concrete shore block to the waterside and the underwater, it is desirable that the compression strength standard of the concrete is 30.58 N / mm ² or more multiplied by 1.3 times the standard of compressive strength.

Referring to Table 2, it can be seen that the concrete specimens of Examples 1 to 9 according to the present invention, to which the biosynthesis accelerating material is added, all have a compressive strength of at least the reference standard.

In addition, it was confirmed that the compressive strength of concrete specimens produced by Examples 1 to 7 decreased as the amount of the biosynthesis accelerating material was increased. In Examples 1 to 4, Example 8 and Example It can be seen that the concrete specimen produced by the method of the present invention has a compressive strength of 30.58 N / mm ² or more, which is the desired compressive strength for a concrete shore block.

The concrete specimens produced by Examples 5 to 7 exceeded the reference compressive strength of 23.52 N / mm ² , which is required for the concrete shore block. However, since the compressive strength is less than 30.58 N / mm ² , Is used in an amount of more than 5 parts by weight based on 100 parts by weight of the binder.

From the results of the compressive strengths of the concrete specimens produced by Examples 1 and 2 and Examples 5 to 7, it can be seen that the incorporation of the two materials as the byproduct of agricultural processing, Of the total amount of water.

The concrete composition having the composition of the present invention and the concrete product manufactured using the above-mentioned composition of the present invention can be used as a bio-growth promoting material, It has been confirmed that excellent durability and long-term stability can be secured when installed in the waterfront and underwater.

<Sensory evaluation of odor of concrete specimen>

Sensory evaluation of specific odors of concrete and biological growth promoting materials were conducted for two types of concrete specimens prepared by Examples 1 to 9 and Comparative Examples, The results are shown in Table 4 based on Table 3 based on the panel list. The value of the odor sensory evaluation result is odorless at a value between 0 and 1, a fine odor at a value between 1 and 2, a slight odor at a value between 2 and 3, and a strong odor at a value between 3 and 4 .

According to Table 4, it was found that the concrete specimens produced by Examples 1 to 4 and Comparative Examples did not have the odor of the concrete itself and the odor peculiar to the biosynthesis accelerating material, and had odorless or very fine odor , It was found that the concrete specimens produced by Examples 5 to 9 had a slight odor.

In addition, in the case where the mixture of soybean-extracted powder was further coated on the surface of the concrete specimen (Example 8 and Example 9), the soybean-extracted powder mixture solution The more the amount of soybean extract powder contained in the soybean powder was, the stronger the odor of the biological growth promoting substance was.

In the case of the concrete specimens produced by Examples 5 to 7 and Example 9, a slight odor peculiar to the biosynthesis accelerating material was slightly generated, whereby the agricultural processing by-products were used in an amount exceeding 5 parts by weight based on 100 parts by weight of the binder It is not preferable to incorporate soybean extract powder in an amount exceeding 1 part by weight based on 100 parts by weight of water.

The specific odor of the bio-growth promoting material can be adjusted to an appropriate level by controlling the content of agricultural processing by-products and the mixing amount of the soybean extract powder in the soybean extract powder mixture in the production of the concrete product using the concrete composition according to the present invention.

<Evaluation of Plant Growth Performance of Concrete Specimens>

The concrete specimens prepared in Examples 1 to 4 and Example 9 and Comparative Example were buried in general soil and seeds of Kentucky Bluegrass, a type of grass, were sown thereon, The results are shown in Table 5. &lt; tb &gt; &lt; TABLE &gt;

According to Table 5, when the degree of leaf growth of Kentucky bluegrass sown in the vicinity of the concrete specimen prepared according to Examples 1 to 4, 9 and Comparative Examples was compared, the results of Examples 1 to 4 and It was found that the growth rate of Example 9 was faster than that of Comparative Example, which means that it was affected by biodegradation promoting materials inside and outside the concrete specimen.

In the case of the concrete specimens produced by Examples 1 and 2, the growth rate was slightly faster than that of the Comparative Examples, so that the agricultural processing by-products were mixed at less than 0.5 part by weight with respect to 100 parts by weight of the binder, It can be seen that the effect of the by-product can hardly be exerted.

In the case of the concrete specimen prepared in Example 9, the degree of leaf growth of Kentucky bluegrass was the fastest. Therefore, the surface application of the biosynthesis accelerating material easily diffuses into the surrounding soil and the Kentucky bluegrass Of the total population.

<Performance evaluation of underwater algae adhesion of concrete specimen>

Table 6 shows the result of measuring the attachment state of underwater birds by immersing the concrete specimen manufactured in Example 4 and Comparative Example in a river.

According to Table 6, it was confirmed that a lot of algae adhered to the surface of concrete specimen at the first month of immersion, and in case of the concrete specimen manufactured by Example 4, the algae were continuously adhered even after a lapse of time.

Particularly, in the case of the concrete specimen manufactured by Example 4, the amount of attached algae per each period was 2 to 3 times as many as that of Comparative Example. This shows that algae were actively grown and grown by dissolution of the growth promoting material incorporated into the concrete test body according to the present invention.
