Description

The ocher ready mixed concrete and the ocher ready mixed concrete {The ready- mixed concrete and product method of the ready- mixed concrete from loess}

The present invention relates to a method for manufacturing ready mixed concrete by mixing clay, which is a clay mineral having excellent far-infrared radiation, and particularly, a process of preparing clay concrete by attaching processed ocher powder obtained by firing ocher fine powder together with cement in manufacturing ready mixed concrete. The present invention relates to a method for producing ocher ready mixed concrete and its ocher ready mixed concrete to neutralize and affect the human body with far infrared rays emitted from ocher concrete.

In general, ocher is a coarse, pale yellow or pink sediment that is coarse and more viscous than kaolin or clay.

Therefore, in order to make the description of the present invention easier, general matters related to loess are described first.

Our country's loess is composed of yellow sands that have flown for hundreds of thousands of years from mainland China. The loess contains four kinds of enzymes: catalase, diphenol oxidase, saccharase, and proteases. It plays a role in decomposing power, fertilizer element, and purification.

In particular, catalase is known to show the highest activity among the elements of soil at present, and this enzyme removes hydrogen peroxide, which provides toxins to organisms, and makes metabolism in the human body. When the toxin called lipid peroxide occurs during the process, aging occurs. If you put the body in good quality loess, it absorbs and dilutes lipid peroxide, which is a toxin in the body, with the strong absorption power of the soil, thereby suppressing aging and maintaining youth. .

Then look at in more detail to distinguish the efficacy of the ocher is as follows.

First, loess has an excellent efficacy of Duhan fever. In other words, natural ocher has the effect of infinite foot heat to draw down the heat described above to cool the head and warm the feet. In addition, it is very beneficial to health because a large amount of far infrared rays, infinite life energy is emitted.

Second, there are 200 million microorganisms beneficial to the human body in ocher, and the energy of far-infrared rays generated from ocher is very beneficial to the human body as a life force.

Third, natural ocherite has excellent automatic humidity control by absorbing when the humidity is high and diverging when drying.

Fourth, it is good for anti-aging, promoting blood circulation, relieving stress, beauty of skin, neuralgia, low back pain, and chronic fatigue with high rate of far-infrared radiation.

Fifth, large amounts of negative ions are released. Because of this effect, in today's buildings, there is a lot of movement to use the loess and loess stone as the present invention for blocking the toxins and environmentally harmful substances of cement. Therefore, if the building is built with such natural ocher, it provides a comfortable living environment by maintaining the most suitable moisture (compatibility) to maintain body temperature.

Sixth, it quickly cleanses other harmful smells such as toilet smell, food smell, and tobacco smell.

Seventh, the interior of the building is comfortable with antibacterial, deodorant, and moisture control to induce a comfortable sleep.

Eighth, to prevent the growth of fungi and various fungi harmful to the human body.

Ninth, it acts to neutralize lipid peroxide, a poison that is bad for the human body.

In other words, loess stone exhibiting many effects as described above has long been proved to be effective, and efforts to utilize as building materials with the trend of well-being have been increased. I know that you have been away.

The reason is that, like ocher-land cement, when it is put into water, it turns into qualitative state, and it is applied to a wall or floor, and when it dries over time, it has strong rigidity.

However, in the case of cement, once hardened, the hardness does not weaken, but in the case of loess, the hardness is weakened and peeling occurs frequently.

Therefore, it was difficult to use the ocher mixed with ready mixed concrete.

The present invention, which solves the above-mentioned problems, relates to a method for producing ready mixed concrete by mixing clay, which is a clay mineral having excellent far-infrared radiation, and particularly, a process for preparing processed clay powder prepared by processing ocher fine powder. In addition to this, it is intended to provide a method of manufacturing ocher ready mixed concrete and ocher ready mixed concrete to neutralize the poison of semen and to have a beneficial effect on the human body by far infrared rays emitted from ocher concrete.

Therefore, the present invention in the ready-mixed concrete manufacturing process, the first step: ocher fine powder is calcined for 1-3 hours in 850 ℃ ± 100 ℃ after cooling, the powder degree 3500 (cm ² / g) ± 500 (cm ² / g) processed ocher powder manufacturing step, the second step: coarse aggregate (37-45%) and fine aggregate (30-40%) to the batch plant, the third step: cement and Injecting mixture A (10-20%) and fly ash (0.5-2%), which is a mixture of processed ocher powder processed in the first step, into a batch plant, and the fourth step: admixture and AE reducing agent (0.03- 0.5%) and water (5-9%) to produce a mixture B, and step 5: mixing the mixture B as a whole to produce a yellow clay ready mixed concrete harmless to the human body but its robustness To provide a high ocher ready mixed concrete manufacturing method.

In addition, the processed ocher powder of the mixture A of the third step, which is the main part of the present invention, is to provide a method for producing ocher ready mixed concrete prepared by selectively adding 10-55%.

In addition, the present invention

The present invention is similar to the conventional one in that it is a ready mixed concrete manufacturing process.

However, the process of the present invention will be described in detail because the processed ocher powder, which is plastically processed together with cement, is added to the ready mixed concrete, and thus far infrared rays are released to neutralize harmful toxicity to the human body.

First, the present invention is the first step: ocher fine powder is calcined for 1-3 hours in 850 ℃ ± 100 ℃ after cooling, processing so that the powder degree 3500 (cm ² / g) ± 500 (cm ² / g) Process the processed ocher powder.

That is, the fine powder loess is cooled by calcination for about 2 hours at 750-950 ° C.

Therefore, the loess of the present invention is to be able to maintain the firmness even when the water soaked after being cured by virtue of this plastic working.

And processing the plastic processed ocher powder to 3500 (cm ² / g) ± 500 (cm ² / g) to prepare a processed ocher powder.

Next, the present invention, the second step: coarse aggregate (37-45%) and fine aggregate (30-40%) is subjected to the step of the batch plant.

In other words, the size of the coarse aggregate (gangjagal, crushed stone and other aggregates, etc.) is preferably mixed about 13-40mm, fine aggregate (sand) is used to satisfy the particle size distribution prescribed by KS standards It is desirable to.

The present invention is a third step: the mixture A (10-20%) and fly ash (0.5-2%) which is a mixture of cement and processed ocher powder processed in the first step is subjected to a batch plant.

This step is the most important step in the present invention. As is applied to all ready mixed concrete, cement makes each material of concrete into a solid element by water and hydration, and fly ash also serves as a substitute for cement. Is a strength enhancer.

In addition, the ocher powder processed in the first step refers to the processed ocher powder.

In addition, the mixture A refers to a mixture of cement and the processed ocher powder, and means that 10-20% of the mixture A in the combined state is added by weight.

For reference, the percentages indicated above are all weight ratios.

Next, the present invention undergoes a fourth step: admixture, AE reducing agent (0.03-0.5%) and water (5-9%) to produce a mixture B.

Here, the AE reducing agent reduces the amount of water used in the ready mixed concrete to increase the strength of the concrete and improve the fluidity of the concrete to improve the site pour work of concrete.

Finally, the present invention is the fifth step: the mixture of the mixture B as a whole through the step of producing the ocher ready mixed concrete is harmless to the human body, but the high rigidity is to manufacture the ocher ready mixed concrete.

That is, all of the above configuration requirements are properly stirred.

This stirring is done through a separate mixer or stirrer,

The mixing time of the mixture is preferably mixed for 36-60 seconds in the mixer when the slump (about the dough) is less than 8cm, it is useful to mix for 25-35 seconds when the slump is 8cm or more.

Meanwhile, the ocher ready mixed concrete manufactured by the manufacturing method of the present invention is moved to a ready-mixed truck or used directly in the field.

That is, the prepared ocher ready mixed concrete can be used to move to the site using a ready-mixed concrete truck.

In the present invention, the processed ocher powder of the mixture A of the third stage, which may be the main part, may be prepared by selectively adding 10-55% of various types of ocher ready mixed concrete.

In other words, the meaning of 10-55% of the processed ocher powder refers to the processed ocher powder contained in the mixture A.

In other words, when the mixture A is viewed at 100%, 10-55% can be selectively administered in the process of coarse clay powder compared with other components cement.

Of course, the strength of the ocher ready-mixed concrete according to this distribution will be explained in detail later in the table.

In addition, the present invention can be prepared by the coarse aggregate of the first step, the machstone aggregate 10-50%.

That is, as described above, coarse gravel or crushed stone is generally used for the coarse aggregate, which means that 10-50% of elvan aggregate is added to improve its functionality.

Of course, the case of this 10-50% elvan rock aggregate refers to the numerical value compared with the coarse gravel or crushed stone when the coarse aggregate introduced is 100%.

Eventually, the ocher ready mixed concrete produced as described above will be listed below, ie, the result of measuring the strength using the ready mixed concrete carried out at the above composition ratios (loading rate of processed ocher powder), but the loess of the present invention The higher the amount of fine powder, the higher the far-infrared radiation energy, the E. coli and Pseudomonas aeruginosa showed 99.8% reduction, and the antifungal effect was excellent.

And the present invention does not only claim the method for producing the ocher ready mixed concrete.

The ocher ready mixed concrete made through the manufacturing method of the present invention described above is also subject to the claims.

Then, in order to explain the ocher ready mixed concrete of the present invention, the conventional standard formulation table and the ocher fine powder of the present invention are mixed with the ratio of the weight of the cement by about 10, 20, 30, 40 and 50% of the mixing ratio. Tables and figures show the results of the strength test of the various examples of the ready mixed concrete.

<Table 2> Standard Specification for Ready Mixed Concrete

The standard specification table of ocher ready mixed concrete of Table 2 is concrete produced by the mixing ratio according to the present invention.

The important point here is that the mixing of each of the components were added so that the 100% by weight ratio, the numerical value in () shown in Table 2 indicates the weight ratio of the added components.

Of course, the composition ratio is all within the numerical value defined in the Claim of this invention.

Then, the table is described in detail as follows.

In the above table, the cement and the processed ocher powder represented by the bold type are defined in the present invention as "mixture A" in a mixed state.

And in the ocher ready mixed concrete manufacturing method of the present invention has been limited to the input amount of the mixture A to 10-20%.

By the way, in the example of Table 2, the input amount of the mixture A was selected to 14.27%, and if the cement is added 12.77%, the fine clay powder is 1.50%.

And in the case of the processed ocher powder of the present invention 10-55% can be selectively added compared to the mixture A, the experiments and specifications according to it are shown in Table 2 above.

That is, in the division, about 10% substitution of the division column refers to the ocher ready mixed concrete containing about 10% of the processed ocher powder contained in the mixture A.

That is, when the mixture A, which is a mixture of cement and processed ocher powder, is 100%, and the processed ocher powder is about 10% compared to the cement, it is classified as about 10% substitution in the column of Table 2. If the compared processed ocher powder is about 20%, it is described in the section called about 20% substitution.

As a result, to accurately analyze the "about 40% substitution" in the table according to an embodiment of the present invention, the mixture A is regarded as 100% in the mixture A added at about 12.27% in the total composition ratio.

In other words, the cement is 193 (kg / m ³ ) is mixed and the processed ocher powder is 140 (kg / m ³ ) is blended to form 14.27% to form ocher ready mixed concrete.

And the processed ocher powder 140 (kg / m ³ ) is 42.04% of the input compared to the cement 193 (kg / m ³ ) is divided into "about 40% substitution" in this division.
