Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an inorganic chloride gel and a method for producing the same, and more particularly, to an inorganic chloride gel which can be suitably used as an inorganic soil hardener and a method for producing the same.

[0002]

2. Description of the Related Art As a conventional soil hardening agent, there is, for example, Portland cement. However, such a conventional cement-based soil hardening agent has a problem that in order to use it as concrete, the required strength cannot be obtained unless aggregates such as sand and gravel are used. . There is also a problem that cement cannot be expected from sludge and incineration ash with cement.

The present invention has been made in view of such conventional problems, and an object of the present invention is to provide a novel inorganic chloride gel which is useful as an inorganic soil hardening agent and a method for producing the same. The purpose is to do.

[0004]

According to the first aspect of the present invention,
An inorganic chloride gel is prepared by mixing equal amounts of an aqueous solution A of a mixture of potassium chloride, silicon chloride and rubidium chloride and an aqueous solution B of a mixture of sodium chloride, potassium chloride, calcium chloride, cobalt chloride and bromine chloride at the same concentration. It is characterized by becoming. The invention according to claim 2, wherein the method for producing an inorganic chloride gel comprises an aqueous solution A obtained by dissolving potassium chloride, silicon chloride and rubidium chloride in water at 50 to 60 ° C; An aqueous solution B obtained by dissolving a mixture of potassium chloride, calcium chloride, cobalt chloride and bromine chloride in water at 50 to 60 ° C. and an aqueous solution B of the same concentration are mixed in equal amounts. The invention according to claim 3 is characterized in that, in addition to the above composition, the composition ratio of the inorganic chloride in the aqueous solution A is 89% by weight of potassium chloride, 10% by weight of silicon chloride, 1% by weight of rubidium chloride, and the aqueous solution B Wherein the composition ratio of the inorganic chloride is 55% by weight of sodium chloride, 30% by weight of potassium chloride, 10% by weight of calcium chloride, 3% by weight of cobalt chloride, and 2% by weight of bromine chloride. .

[0005]

According to the present invention, when a hardened material composed of inorganic chlorides such as potassium chloride, sodium chloride, calcium chloride, cobalt chloride, rubidium chloride, bromine chloride and silicon chloride, Portland cement and water are stirred. In addition to the hydration reaction of Portland Cement, needle-like crystals due to anion binding are generated, and the organic and inorganic substances can be combined by a reaction that changes into a crystal without moisture beyond hydration A good modifier is obtained. Accordingly, the cement for hardening has excellent effects such as chemical resistance, heat resistance, water resistance, electric resistance, weather resistance, etc., which exceed the hardening effect of the hydration reaction of the hardening cement, and maintains the hardening properties for a long time.
Also, without using aggregates such as sand and gravel necessary for conventional concrete, it can be solidified using the soil at the site as it is, and sludge that hardens with ordinary Portland cement can not be expected, There is an effect that incineration ash and industrial waste can be solidified.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments.
In Examples, parts and percentages are by weight unless otherwise specified.

EXAMPLE 1 2 kg of a mixture of inorganic chloride consisting of 89% of powdered calcium chloride, 10% of silicon chloride and 1% of rubidium chloride
Was dissolved in 18 liters of water at 50 to 60 ° C. to prepare an aqueous solution A. Similarly, sodium chloride 55%, potassium chloride 30%, calcium chloride 10%, cobalt chloride 3
2k of a mixture of inorganic chlorides consisting of 2% bromine chloride and 2% bromine chloride
g was dissolved in 18 liters of water at 50-60 ° C to prepare an aqueous solution B. An equal amount of the two aqueous solutions at a temperature of 50 to 60 ° C. was mixed to form an inorganic chloride gel. This gel is mixed with Portland cement about 10%,
For example, it can be used for sludge hardening containing harmful substances such as heavy metals.

Example 2 1 kg of a mixture of inorganic chloride consisting of 89% of powdered calcium chloride, 10% of silicon chloride and 1% of rubidium chloride
Was dissolved in 18 liters of water at 50 to 60 ° C. to prepare an aqueous solution A. Similarly, sodium chloride 55%, potassium chloride 30%, calcium chloride 10%, cobalt chloride 3
1k of a mixture of inorganic chlorides consisting of 2% bromine chloride and 2% bromine chloride
g was dissolved in 18 liters of water at 50-60 ° C to prepare an aqueous solution B. An equal amount of the two aqueous solutions at a temperature of 50 to 60 ° C. was mixed to form an inorganic chloride gel. This gel can be used in a cement method which does not require solidification of incinerated ash and washing of sea sand by mixing about 10% with Portland cement.

[0009]

As described above, the present invention has the following advantages. (1) It shows a state completely different from the result of hardening of the conventional Portland cement. That is, the present invention is a novel organic / inorganic mixture-improving agent which is improved to change into a crystal without water, which exceeds the hydration reaction stage. (2) Since the aggregate is not selected, the soil at the site is solidified as well as sand (including sea sand) gravel, as well as volcanic ash, incineration ash, livestock dung, sludge, clay, shirasu, black soil, sludge, and other industrial waste. I can do it. (3) It has a deodorizing effect by solidifying harmful substances, preventing secondary pollution and removing odors. (4) In the case of road pavement work, the construction is simple because no roadbed material such as gravel or crushed stone is required unlike the conventional case.
