Description

Manufacturing method of loess mortar {Manufacturing method of functional yellow clay malt}

The present invention relates to a method for manufacturing a functional loess mortar, and by increasing the density of loess mortar and securing an action reaction area to prevent the contraction action of loess during solidification, thereby supplementing mechanical properties such as cracking to produce a cement in which harmful chemicals are discharged. It relates to a method for producing loess mortar that has continuity in beneficial actions such as cation exchange ability.

From the past until recently, the functions of loess have been gradually revealed, and attempts to use loess as various building materials are increasing. It has been used as a building material since ancient times, and everyone knew that loess is a building material and has beneficial effects.

On the other hand, despite the beneficial effects of loess as described above, the use of loess as a building material has been discarded as buildings become taller and larger in modern times. Modern buildings are composed of concrete, and when concrete is used instead of ocher, air permeability is very low, and mold is generated due to this. Fungi create a favorable environment for pests to thrive. In addition, the nanogas emitted from the concrete accumulates and has a harmful effect on the human body.

In order to solve the above problems, research to replace concrete and increase the environmental friendliness of loess is ongoing. For example, Korean Patent Publication No. 2001-0083811 discloses the technical idea of 'loess extract for building materials and loess tiles, loess mortars, loess bricks and loess balls using the same as raw materials, and their respective manufacturing methods'. This technical idea has advantages in terms of using building materials as raw materials for loess extract, but it seems that the effect of loess extract itself cannot be sustained semi-permanently.

In addition, by supplementing the strength through porous feldspar, only the environmental friendliness function is emphasized in the prior art, and the loess used in the field can be utilized as a building material.

1 is a flowchart configured according to a preferred embodiment of the present invention;

Hereinafter, with reference to the accompanying drawings, it will be collectively described for the configuration of the present invention and the resulting action and effect.

Advantages and features of the present invention, and a method for achieving them will become apparent with reference to the embodiments described below in detail in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various different forms, and only this embodiment serves to complete the disclosure of the present invention, and common knowledge in the technical field to which the present invention pertains It is provided to fully inform those who have the scope of the invention, and the present invention is only defined by the scope of the claims. In addition, like reference numerals refer to like elements throughout the specification.

The present invention improves the mechanical properties such as cracking by increasing the density of loess mortar and securing the action reaction area to prevent the contraction action of loess when solidified, thereby replacing cement from which harmful chemicals are discharged, and beneficial actions such as cation exchange ability. It should be noted that it relates to a method for manufacturing loess mortar with continuity.

To this end, as shown in FIG. 1, starting material generation step (S100) of collecting loess, drying it, pulverizing it to a set size to form fine loess, and selecting porous rocks and then crushing them to a set size (S100) ; By stirring the fine loess and the basic material so that the fine loess flows into the microcavities existing in the basic material, a mixture with a controlled reaction area and density is created, and by stirring the liquid additive in the mixture, the fine loess is absorbed into the microcavities A composition generating step (S200) of generating a composition in an attached state; In order to control the moisture of the composition, the drying step (S300) of natural drying in a state of blocking direct sunlight without applying artificial force to control the moisture of the composition; There is a characteristic.

The starting material generating step (S100) has the purpose of collecting loess and porous rocks. In particular, for porous rocks, microcavities corresponding to or larger than the particle size of loess should be taken. In this case, the term porous rock refers to porous feldspar.

Feldspar is generally kaolinized, pyrolized, chlorinated, or montmorillonite through weathering or hydrothermal alteration, and the alteration of feldspar is accompanied by changes in mineral composition as well as surface texture. Microcavities are observed on the weathering surface of rocks, and these cavities increase the specific surface area related to the reaction area and are related to the elution and adsorption of ions. The porous feldspar employed in the present invention is a weathered feldspar porphyry which will be filled with secondary mineral clay minerals in the process produced by weathering. Due to this porous structure, the specific surface area and cation exchange capacity are increased.

As a whole, the mixing of loess and porous feldspar increases the specificity of clay minerals and benefits to the human body.

The composition generating step (S200) is a step of inducing compression between the basic materials consisting of crushed and crushed fine loess and crushed porous feldspar to achieve the above-mentioned purpose. In the stirring operation, the fine loess naturally flows into the pores of the microcavities of the porous feldspar and is attached to the surface by the clay minerals inside the microcavities of the porous feldspar to create a mixture. In other words, the fine loess is introduced into the microcavity of the porous rock to increase the density, thereby guaranteeing strength during solidification, and the reaction area is increased to improve the cation exchange capacity.

At this time, even if the fine loess is attached to the inside of the microcavity of the basic material, it will not be possible to remove all the pores. So, the liquid additive is stirred into the pore area of the basic material and fine loess to penetrate into the pore area. In terms of the overall bonding state, loess is inflowed between the microcavities of the porous feldspar, and additives are infiltrated between the microcavities and the loess.

The drying step (S300) forms the composition in a dry state by removing moisture from the liquid additive. The loess mortar produced in this way has excellent environmental compatibility and actively prevents cracking due to the strength and bending properties of porous feldspar and loess due to the combination of loess and the shrinkage that occurs when the loess solidifies.

A more detailed description is as follows.

The starting material generating step (S100) includes a loess drying step (S110) of collecting and drying loess sediment; loess grinding step (S120) of grinding the dried loess to a set size to form fine loess; Including consisting of; a basic material generation step (S130) of selecting a porous rock and crushing it to a set size to generate a basic material, wherein the composition generation step (S200) is present in the basic material by stirring the fine loess and the basic material Mixture generation step (S210) of producing a mixture with a controlled reaction area and density by allowing micro-loess to flow through the microcavities: Additives that produce a composition by stirring a liquid additive in the mixture to attach micro-loess to the microcavities stirring step (S220); This includes adding a solidifying agent to the composition in a state of adding an eco-friendly solidifying agent to the composition and stirring it so that the solidifying material is in close contact with the surface of the composition (S230).

The composition generating step (S200) further includes a solidifying material addition step (S230), which includes adding a powdery solidifying agent in which alumina silicate and calcium oxide are mixed. It is an inorganic solidifying material for loess. Since the solidified material does not generate rapid heat during hydration reaction, it is safe to handle, does not generate dust or odor due to high heat, and its alkalinity tends to be lower than that of general cement.

The additive stirring step (S220) stirs an additive made of crude vinegar vinegar in the mixture. At this time, it is natural that more water can be added to control the amount of crude vinegar.

When bamboo is heated in an enclosed space (charcoal kiln or carbonization furnace) in the presence of dilute oxygen, it pyrolyzes to obtain bamboo charcoal and at the same time produces white smoke. This is called carbonization of bamboo, and when the generated smoke (gas and water vapor containing various components) is cooled, a blackish-brown liquid is obtained. If this liquid is left alone, a yellowish oil floats on the surface, a transparent yellowish-brown liquid is formed in the middle part, and a black oily liquid is obtained at the bottom. At this time, the transparent yellowish-brown liquid in the middle is the crude bamboo vinegar (crude bamboo vinegar).

The present invention is characterized in that it promotes odor purification by using crude bamboo vinegar, which has less tar than wood vinegar, is transparent and has a soft smell. In order to produce crude bamboo vinegar, bamboo is carbonized, and there are several methods for carbonization, such as the celebration coal refining method, the simple coal refining method, and the mechanical coal refining method. The crude bamboo vinegar produced in this way is disinfected and purified by the action of 13 kinds of rare elements such as 200 kinds of organic acids and minerals. In particular, it improves the cation exchange capacity of porous feldspar and loess while continuously purifying odors.

In order to examine the mechanical properties and environmental compatibility of loess mortar subjected to the steps presented by the present invention, a specimen was prepared as follows, and compressive strength, cation exchange capacity, purification ability, etc. were tested.

<Production of specimen>

In Example 1, a composition consisting of 55 to 60% by weight of fine loess, 27 to 30% by weight of porous rocks, 8 to 10% by weight of powder solidifying material, and the remainder of crude bamboo vinegar was produced, and in Example 2, 65 to 70 fine loess by weight. A sample was prepared through a drying step (S300) by creating a composition consisting of weight%, porous rock 17-20% by weight, powder solidifying agent 8-10% by weight, and the remainder, crude bamboo vinegar, and sold on the market as Example 3 Samples were prepared with loess mortar. Samples of Examples 1, 2, and 3 were mixed in a 1:1 ratio with water to prepare a specimen according to KS L ISO 679.

<Compressive strength test method>

It was carried out in accordance with KS L ISO 679, and f = P/A (P: Maximum load (N), A: The maximum load displayed by the testing machine was divided by the cross-sectional area of the specimen by the calculation formula of the test ^{cross-sectional area (mm 2 ) in contact with the platen to be obtained in MPa.} Compressive strength was tested at 14 days of age.

division Compressive strength (MPa) Example 1 16 Example 2 14 Example 3 9

<Comparison table of bending strength>

As shown in Table 1 above, Example 1 prepared at the preferred weight % suggested by the present invention had the highest compressive strength of 16, and Example 2, which had a different ratio of loess and porous rock, was compressed even though the mixing ratio of loess was increased. The strength decreased, which is considered to be due to the contraction action of the loess itself. It was confirmed that the commercially available loess mortar has a compressive strength of 9 MPa.

Meanwhile, in Table 1 above, the compressive strength at 14 days of age was compared, but the compressive strength at 28 days was 19 MPa in Example 1, 17 MPa in Example 2, and 10 MPa in Example 3. It can be seen that the preferred embodiment 1 of the present invention has excellent mechanical properties.

<Cation exchange ability experiment>

Cation exchange capacity indicates the total amount of adsorbed cations in a form that can be exchanged with other cations by electrical attraction at a specific pH, and is related to material change, migration, and mineral weathering in an open environment. For this, an experiment was performed using the 1N-ammonium acetate leaching method using the samples of each example without preparing a specimen.

division Cation exchange capacity (meq/100g) Example 1 131.4 Example 2 129.5 Example 3 110.2

<Comparison table of cation exchange capacity>

As shown in Table 2 above, the cation exchange capacity of loess itself is judged to be excellent, but it was confirmed that the cation exchange capacity was rapidly increased by the porous feldspar presented by the present invention. In particular, it was confirmed that even if the loess ratio was increased as in Example 2, the cation exchange capacity decreased as the porous feldspar decreased.

<Purification ability experiment>

After destroying the specimen and spraying it on the manure of a general livestock facility, the ammonia (NH ₃ ) reduction ability was tested over time.

Measurement time (hr) Example 1 Example 2 Example 3 0 2.7 2.7 2.7 3 4 4 5.6 5 4.3 5 6.5

<Ammonia (NH ₃ ) reduction capacity comparison table>

Example 1 of Table 3 above _{is confirmed to have an excellent effect on ammonia (NH 3} ) reducing ability, which is determined to be due to the purification ability of crude vinegar. _{Other examples also showed excellent results in ammonia (NH 3} ) reduction ability than artificial samples such as cement, but there is a problem in that the problem to be solved by the present invention cannot be solved. In Example 1, the action of loess and crude bamboo vinegar penetrating into the microcavities of the porous rock is expressed as the measurement time elapses, so that a continuous purification action can be performed.

Based on the results of all the above experiments, the composition of the present invention is a powder solidifying material in which 55-60 wt% of fine loess, 27-30 wt% of porous rock, alumina silicate and calcium oxide are mixed. It is preferable to consist of 8 to 10% by weight, and the remainder, crude bamboo vinegar.

As described above, the present invention guarantees the continuity of beneficial actions such as the ability to exchange ambidextrous rocks by utilizing the advantages of loess, crude bamboo vinegar, and secondary clay minerals remaining inside the microcavities of the porous rock. In addition, by supplementing the strength through porous feldspar, only the environmental friendliness function is emphasized in the prior art, and the loess used in the field can be utilized as a building material.
