Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing high-strength concrete in which cracks hardly occur.

[0002]

2. Description of the Related Art Conventionally, various methods have been used to prevent the occurrence of cracks in concrete. As a crack preventing method, there are methods such as adjusting a cement component for producing concrete, mixing various crack preventing agents, and increasing the density of concrete by tamping the cast concrete.

On the other hand, at present, little consideration is given to the water supplied during the production of concrete. That is, when producing concrete, tap water is usually used, but at present, it is used without removing impurities contained therein.

[0004]

However, it is well known that in the production of concrete, water is bound to the cement component by a hydration reaction, and that water is an important factor that influences the binding force with the cement particles. Is a matter of.

[0005] Therefore, in the hydration reaction, if the cement component coagulates or impurities are present, the contact with water becomes incomplete, so that the bonding force between the cement particles and the aggregate is weak and cracks are likely to occur. It becomes concrete.

The present invention has been made based on the above-mentioned circumstances. By changing the characteristics of water supplied to concrete, the binding force with cement components or aggregates is strengthened and cracks are generated. An object of the present invention is to provide a concrete manufacturing method capable of obtaining high-strength concrete that does not have high strength.

[0007]

In order to achieve the above-mentioned object, the method for producing concrete according to the first aspect of the present invention is to provide a mixing and stirring tank of cement and aggregate in which water is passed through a magnetic field of a magnetic material. It is characterized in that high strength concrete is obtained by supplying and stirring.

The method for producing concrete according to a second aspect of the present invention is the method for producing the concrete according to the first aspect, in which a magnetic field is provided on the outer periphery of the pipe for supplying water to the mixing and stirring tank of cement and aggregate. The feature is that water is magnetized by providing a body.

Further, the method for producing concrete according to claim 3 of the present invention is the method for producing concrete according to claims 1 and 2, wherein the outer periphery of a pipe line for supplying water to a mixing and stirring tank of cement and aggregate. It is characterized in that an S-pole magnet and an N-pole magnet are arranged opposite to each other.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below.

In the method for producing concrete of the present invention, water is magnetized by passing a magnetic field of a magnetic material, and this water is supplied to a mixing and stirring tank of cement and aggregate to stir, whereby high strength concrete is obtained. Is to get.

As one example thereof, as shown in FIG. 1, by arranging a magnetic body 2 on the outer circumference of a conduit 1 for supplying water to a cement / aggregate mixing and stirring tank 4, water is magnetized. The magnetized water is supplied to the mixing and stirring tank 4 and stirred together with the cement and the aggregate.

In this structure, the water supplied to the mixing and stirring layer 4 is obtained from tap water as in the conventional case.
Since the amount of water supplied by ordinary tap water is limited, tap water is stored in the water tank 3 and the water tank 3 and the mixing and stirring tank 4 are stored.
And a magnetic body 2 are provided on the outer circumference of the pipe 1.

The conduit 1 is made of a non-magnetic material such as a vinyl chloride pipe, a copper pipe, a stainless steel pipe or the like. This is done so that the magnetic force of the magnetic body 2 provided in the conduit 1 does not leak, as will be described later.

As an example of the magnetic body 2 provided in the conduit 1, as shown in FIG. 2, magnets of S pole 5 and N pole 6 are arranged opposite to each other on the outer circumference of the conduit 1 formed of a non-magnetic material. , S like this
A desired magnetic flux density is obtained by combining a plurality of poles 5 and N poles 6.

In the experiment, a strong magnet having a magnetic flux density of tens of thousands of gausses was used as the above-mentioned magnetic material, so that a concrete having a dense and strong tenacity that had never been found could be obtained.

However, it is necessary to judge how much magnetic force is desired for the above-mentioned magnetic material, together with how much strength is expected of the concrete after hardening or the problem of fluidity related to workability of concrete. There is.

Next, the magnetized water obtained by the above method is transferred to the mixing and stirring tank 4 and supplied in a shower shape from above the mixing and stirring tank 4, and the cement and the aggregate mixed in the tank are stirred. I was able to get very tenacious concrete. In addition, the hardened concrete has very high strength.

As the mixing / stirring tank 4, a concrete mixer is used in actual concrete production.

By the way, by using the magnetized water in the production of concrete as described above, a very viscous concrete can be obtained, and one of the reasons why the hardened concrete has high strength is water. It is considered that the magnetism caused a considerable amount of impurities such as chlorine, calcium, and nitrogen in the water to disappear, and the binding force between the water and the cement particles and the aggregate was enhanced by this.

It is also considered that magnetizing water causes the PH value to rise above that of normal water, thereby approaching the alkali value of the cement component, thereby improving the familiarity with the cement component.

In any case, the magnetizing of water strongly affects the hydration action of the cement component, and the contact efficiency of the water with the cement component and the aggregate is improved, so that the water, the cement component and the bone are improved. The binding force with the material increases,
A very dense and viscous concrete was obtained, and the unevenness of concrete density and the impurities that were the cause of cracks in the cement were reduced, resulting in a very high strength concrete after hardening.

In the above description, the magnetic substance for magnetizing the water is provided on the outer circumference of the conduit from the water storage tank to the mixing and stirring tank. However, it is provided in the water supply process in the previous stage of the water storage tank. Good.

[0024]

As described above, according to the method for producing concrete of the present invention, water is magnetized by passing the magnetic field of the magnetic substance, and this water is supplied to the mixing and stirring tank of cement and aggregate. By doing so, it is possible to obtain highly dense concrete that is extremely dense and is unlikely to cause cracks.

In the present invention, the conventional water pipeline is utilized by magnetizing the water by providing a magnetic material on the outer circumference of the pipeline for supplying water to the cement / aggregate mixing and stirring tank. Then, magnetized water can be produced, the cost burden is light, and high-strength concrete can be easily obtained.

Therefore, according to the method for producing concrete of the present invention, it is not necessary to use a crack preventing agent as in the prior art, and the magnetic substance for magnetizing water can be used semipermanently. It is possible to obtain a high-strength concrete manufacturing method that is cost-effective.
