EMBODIMENT OF THE INVENTION Hereinafter, the structure of this invention is demonstrated in detail.

In the manufacturing method of soil concrete or soil concrete block using the swelling agent or the repairing agent according to the present invention, one selected from the group consisting of clay soil containing clay or clay sand including clay soil, paper sludge, constant sludge and stone powder soil The above soil components can be used. At this time, the soil component to be used varies depending on the place or condition of the calculation, but contains about 5 to 15% of moisture and the content is not constant, so mixing with other admixtures to absorb moisture and homogeneous is essential for the process. .

The admixture used in the present invention is characterized in that at least one selected from an inorganic admixture including blast furnace slag, slaked lime, gypsum, fly ash, clay silicate, volcanic ash, siliceous powder and silica fume, the inorganic admixture is used to improve the bonding strength do. At this time, it is preferable to use lime-based for the initial strength enhancement, slag for the later strength enhancement, and gypsum for the formation of ettringite. In addition, the admixture is added in an amount of 20 to 60 wt% based on the soil component.

In addition, an expansion agent is added to offset the dry shrinkage due to the decrease in the binding force due to the addition of the soil, wherein at least one selected from the inorganic system containing sodium Calcium Sulfur Aluminate (CSA) -based expansion cement or sodium alginate 1-10 parts by weight of one or more selected from natural oils is added to the soil component.

In addition, a water refining agent is added to homogenize and reduce the content of water, and at this time, 5 to 30 parts by weight of one or more selected from natural organic admixtures including agar and agar are added to the earthen ingredients.

In the present invention, as a coarse aggregate, aggregates of all sizes used in ordinary ready-mixed concrete can be used, but since soil particles are fine, it is preferable to use crushed aggregates having a size of 13 mm or less which is not used in conventional ready-mixed concrete in terms of physical properties and economics. desirable. At this time, 20 to 50% by weight of crushed aggregates are usually used in 20 to 50% by weight of the soil mixture, and about 10 to 40% by weight of steel sand having a low absorption rate is used as fine aggregates (sand). Can be reduced.

It is preferable to use ordinary portland cement or slag cement within 5 to 15% by weight depending on the addition of soil, and to use the soil mixture at about 20 to 50% by weight in terms of color, texture, fluidity and strength.

The mixed water is adjusted to a water / binder (cement and soil mixture) ratio in the range of 40 to 100% by weight so that the slump is 5 cm or more. At this time, if the slump is increased, the moldability is improved, but it is not preferable in terms of water absorption and strength due to excessive moisture addition.

In addition, in order to improve workability and resistance to frost resistance, a water reducing agent may be further added, wherein the water reducing agent may include one or more high-melting agents selected from the group including naphthalene-based and melamine-based or vinsol-based and modified lignin-based. One or more AE water reducing agents selected from the group can be used, which is added in an amount of 0.5 to 1.5 parts by weight based on the mixture (excluding water).

At this time, by applying at least one resin selected from the group consisting of polyethylene resin, polystyrene resin, polypropylene resin, melamine resin and fluorine resin that can improve the surface wear resistance and gloss on the form surface, water-soluble after pouring It improves durability and freezing resistance by promoting the formation of etringite on the surface without using acrylic or the like. Here, the ettringite is a compound having a chemical formula of 3C ₃ A · CaSO _{4 ·} 32H ₂ O to constrain the water molecules of 32 molecules, consequently to restrain the movement of soil particles to strengthen the bond.

In the present invention, in the preparation of earthen concrete blocks, 20 to 60 parts by weight of permeable concrete is poured on the mixture, and given by spherical and surface vibration.

In addition, when molding given the concrete vibration and surface vibration, the vibration molding uses a shaking table that can give left and right and up and down vibration, and for the first agitation, the concrete vibration with an amplitude of 30 to 100 mm and a vibration speed of 2 to 5 hz is used. After 10 to 20 seconds, surface vibrations of 5 to 20 mm in amplitude and 10 to 20 hz oscillation are performed for 20 to 30 seconds for the second moisture rise and densification. It is because it is uneconomical and stirring is difficult if it is less than the said minimum range.

The mixture was adjusted to 600 g of mixed water (53% of water / binder ratio) so that the slump was about 5 cm, and kneaded by adding 1% (21.25 g) of naphthalene-based high-fatting agent (Powercon 1000) except water.

As a result of the experiment, there was no entanglement in the mixing using soil, and a good dilution was obtained in mixing, water was well infiltrated, and the mixing was good. However, hydration and strength development were slow and shrinkage was relatively high. The hygroscopicity of the specimen was excellent in the repeated process of wetting and drying, and the compressive strength was about 20 kg / cm ² .

<Example 3>

In order to compensate for the decrease in strength of soil-containing soil concrete, an experiment was conducted to add sodium alginate, a natural organic admixture, as an inorganic admixture and an expanding agent. At this time, the top soil of the same natural state as that of Example 1, namely, ocher was used as the main component of the soil concrete.

First, after collecting the natural yellow soil, add 50g of lime, 50g of fly ash and 50g of gypsum (50 parts by weight of non-organic admixture), and 30g (6 parts by weight) of sodium alginate as a swelling agent for 500g of soil. One soil mixture was put into a rotary ball mill and ground and mixed in advance so as to obtain a homogeneous powder.

The mixture was adjusted to 400 g of mixed water (water / binder ratio 40%) so that the slump was about 5 cm, and kneaded by adding 1% (20.3 g) of naphthalene-based high-fatting agent (Powercon 1000) except water.

As a result, as shown in Table 1, it was possible to obtain a very good dilution for kneading, the water quickly soaked and blended well, the hydration and strength expression is rapidly progressed, and a certain amount of expansion appeared. There was little hygroscopicity of the specimen during the repeated wetting and drying, and the compressive strength was about 240 kg / cm ² .

<Example 4>

In order to compensate for the decrease in strength of soil-containing soil concrete, an experiment was conducted to add agar, a natural organic admixture, and sodium alginate as a swelling agent. At this time, the top soil of the same natural state as that of Example 1, namely, ocher was used as the main component of the soil concrete.

First, take the natural yellow soil, and then 50g of lime, 50g of fly ash and 50g of gypsum (50 parts by weight of inorganic-free admixture), 30g of sodium alginate (6 parts by weight) as a scavenger, and agar as a repair agent. 125 g (25 parts by weight) of the added mixture was put into a rotary ball mill and ground and mixed in advance so as to obtain a homogeneous powder.

The mixture was adjusted to 700 g of mixed water (water / binder ratio 60%) so that the slump was about 5 cm, and kneaded by adding 1% (21.55 g) of naphthalene-based high-fatting agent (Powercon 1000) except for water.

As a result, as shown in Table 1, it was possible to obtain a good dilution in the mixing, the water is well infiltrated and well blended, the hydration and strength was rapidly developed. Shrinkage was also very small moisture absorption of the specimen was born receive almost no iterations from the wet and dry compressive strength was about 120 kg / cm ^2.

<Comparative Example 1>

As a comparative example, a strength reduction test was carried out when sandy soil was added to ordinary concrete. In this comparative example, sandy soil, which can be easily collected from the surroundings, was used as the main component of the soil concrete.

First, after collecting the natural sandy soil, 100 g of lime, fly ash 150 g and 100 g of gypsum (58 parts by weight of non-machined admixture) are mixed with 600 g of sandy soil, and then crushed in advance to make a homogeneous powder. And mixing.

950 g (45.23%) of the soil mixture thus obtained is mixed with 580 g (27.61%) of crushed aggregate (gravel) of 13 mm or less, fine aggregate (420 g (20%) of fine sand), and 150 g (7.14%) of Portland cement. It was done. The mixture was adjusted to 800 g of mixed water (73% water / binder ratio) so that the slump was about 10 cm, and kneaded by adding 1% (21 g) of the total weight except water to naphthalene-based high softening agent (Powercon 1000). See Table 1).

As a result, as shown in Table 1, it was not well rubbed, the tangling phenomenon appeared in the formulation using the soil was clear. Hydration and strength development did not progress well, so it was difficult to measure the strength and showed very high shrinkage.
