Description

Solidifying agent composition for soft ground containing polysilicon sludge and iron dust and construction method using the same {Solidifying Agent Composition for Soft Ground Containing Polysilicon Sludge and Iron Dust and Construction Method Using Thereof}

The present invention relates to a solidifying agent composition for soft ground containing polysilicon sludge and iron dust and a construction method using the same. More specifically, it relates to a solidifying agent composition for soft ground containing polysilicon sludge and iron dust and a construction method using the same. More specifically, it relates to a solidifying agent composition for soft ground containing polysilicon sludge and steel dust, and a construction method using the same. It relates to a solidifying agent composition for soft ground containing polysilicon sludge and iron dust that can develop a certain strength when strength is developed.

In general, ground solidification agents include Portland cement and/or slag cement.

In particular, as a conventional ground solidification agent, Portland cement is used as the main raw material and some pozzolan material is added to it. Ca(OH) ₂ generated through the hydration reaction of cement reacts with the pozzolan material to increase long-term strength and It improves durability and is an appropriate mixture of several stimulants. It can be used in powder form, but as described above, it is mainly used as a paste to maximize the agitation effect.

However, when these solidifying agents are mixed with soil, there is a problem that a large amount of solidifying agent must be used to obtain the desired compressive strength.

In order to solve the above problems, solidifying agents containing crushed blast furnace slag fine powder, anhydrous gypsum, or alkali metal salt compounds have been introduced, but it is difficult to secure sufficient initial strength when the solidifying agent is mixed with soil, and long-term strength is low. And there is a problem that durability is reduced.

In addition, in order to solve the above problems, a method of excessively adding alkali metals is being considered. However, if the alkali metals are excessively added, work becomes difficult due to reduced fluidity, and long-term strength and durability are reduced, so it is necessary to solidify the alkali metals. The amount of substance used must be increased.

Therefore, the general soil solidification agents known to date not only have strength problems in the early and mid- to long-term, but also have the problem of requiring the use of an excessive amount of solidification agent.

In particular, when the solidifying agent is used excessively, there is a problem in that heavy metals such as hexavalent chromium are used in large quantities, which may cause environmental problems.

Meanwhile, the above solidifying agents, especially ground solidifying agents, are often used in coastal areas and coastal areas, and the soil in these areas not only contains a large amount of salt, but also because salt continuously flows in from seawater. When using a general ground solidification agent, the solidification agent expands due to salt, causing problems such as cracks or partial destruction.

In particular, peeling of the surface of a structure or the occurrence of initial defects or cracks facilitates the movement of deterioration factors and accelerates the progress of deterioration. Therefore, to ensure the stability and performance of structures, especially reinforced concrete structures, repair/reinforcement must be carried out in the early stages of deterioration. There is a need to suppress further deterioration and improve durability.

Therefore, after removing the concrete part containing deterioration factors such as delamination or fall-off of the cross-section of the structure due to deterioration of concrete, corrosion of steel, or other causes, filling or spraying cross-section restoration material is required to restore the cross-section to its original performance and form. It is common to carry out repairs after construction.

As a method of reinforcing such structures, specifically concrete structures, it is common to repair/reinforce cracks in concrete structures using packers and repair reinforcements.

As an example of repairing such cracks, a method of repairing/reinforcing the structure by mixing powdered or suspended chemical stabilizers, mainly cement, into the in-situ ground has been used.

However, recently, environmental problems caused by hexavalent chromium in cement have been emerging. This is because if hexavalent chromium contained in cement components is excessively leached into the soil, there is a high possibility that problems of soil contamination will occur. . To solve this problem, it is necessary to minimize the amount of cement containing hexavalent chromium.

Meanwhile, polysilicon is also called poly crystalline silicon. Initially, it was mainly produced for use in CPU boards, and its production was not large, but recently, due to environmental problems such as global warming, it has been replaced with fossil fuels due to restrictions on CO ₂ gas emissions. The solar energy industry, an alternative fuel industry, is developing in order to curb the use of energy and cope with problems caused by limitations of fossil fuel resources. Along with the development of the solar energy industry, the production of polysilicon, a key basic material of the solar energy industry, is increasing. Technology and production are also increasing.

This polysilicon is manufactured through a series of processes of producing metallic silicon from highly refined silica sand (quartz) obtained by refining silica stone and converting it into chlorosilane (also known as monosilane) and trichlorosilane. It is a generally known manufacturing process. The Siemens method, FBR method, and metal refining method are widely known as polysilicon manufacturing technologies.

In addition, waste is generated in the form of sludge from the series of processes for manufacturing the above-mentioned polysilicon. With the development of the solar energy industry, the amount of sludge generated is also increasing due to the increase in production of polysilicon, a key basic material of the solar energy industry. Although it is rapidly increasing, it is being treated as industrial waste and is being discarded as is, without finding an appropriate recycling method. This is causing another environmental problem due to the lack of disposal sites and the increase in disposal costs.

As a recycling technology for various industrial wastes, domestic registered patent publication number 10-0502070, domestic registered patent publication registration number 10-0921334, domestic registered patent publication number 10-0900779, and domestic open patent publication number 10-2009- No. 86862 discloses an industrial waste recycling technology that mixes cement, etc. with coal ash, blast furnace slag, fly ash, etc. and recycles them as fill materials. The inventors according to the present invention used the sludge generated in the polysilicon manufacturing process to produce a ground solidification agent. When recycled, the water contained in the sludge can be used together with lightweight fluid fillers such as fly ash, steel slag, incineration ash, and steelmaking slag powder to produce a concrete composition without the use of cement, which develops strength through natural curing. Taking this into account, the present invention was completed.
