Description
The present invention relates to an environment-friendly soil packaging composition and a method for constructing soil packaging using the same, more specifically, 50 to 90% by weight of soil such as masato, ocher, clay, and surface soil of mine, and
In general, road pavement is a road structure that is processed to enhance the protection and flatness of the road surface, and to facilitate the passage of people and the driving of the vehicle.
Road pavement is classified into bitumen (asphalt) pavement, concrete pavement and block pavement according to the material of the surface layer. The bitumen pavement is the surface layer is composed of aggregate such as crushed stone by asphalt or tar. It is called as pavement, tar pavement, etc., and currently occupies most of the roads around the world.
Concrete paving is concrete laid on the surface layer.In addition to concrete or ordinary concrete pavement with wire mesh embedded in concrete, there are reinforced concrete pavement and prestressed concrete pavement. Block pavement includes stone, brick, cement, Various blocks such as wood and asphalt are laid on the surface layer, and they are not used for roadways but are used for sidewalks and plazas.
Meanwhile, in recent years, a pavement method using environmentally friendly but not harmful to human body has been applied to bicycle roads and sidewalks. However, most soil pavement methods use cement or polymer as the main binder and use pozzolanic materials such as slaked lime, gypsum, limestone, blast furnace slag, fly ash, metakaolin, silica fume as additives to improve the function. have.
In addition, the conventional cement or asphalt-based pavement method has been installed in many fields with very easy workability and low price, but requires coal or petroleum to produce cement, and consumed coal and petroleum resources are combustion process Since limestone used to generate enormous CO 2 gas and used as a raw material of cement is composed of CaCO 3 is the main raw material to generate CO 2 gas in the production of cement, there is a problem that the use of cement itself causes environmental pollution. That is, CO 2 gas generated from cement production is one of the main causes of environmental pollution and air pollution.
In addition, the pavement layer by paving materials such as cement and asphalt is a pavement that disconnects the underground ecosystem and the surrounding ecosystem, and artificially prevents the release of beneficial substances from the soil, causing rare diseases. Recently, on the basis of many environmental problems arising from such cements, awareness of the reduction of cement usage is spreading internationally. For example, the concept of using a material that does not fire is introduced. Various non-cement materials are being developed. For example, there is a newly developed inorganic binder called geopolymer or mineral polymer or organic polymer. However, there is no packaging material developed by the geopolymer technique.
Cement reduction products and technologies are being developed in consideration of this shift in environmental and industrial awareness. For example, Patent No. 438138 describes a technique for limiting the range of natural soil, cement and solidification composition, and inducing excellent physical properties by controlling the size of particles. It has been described that the clay mixture, coarse sludge, coarse sludge, coarse soil, and clay powder are mixed with soil, expansion agent, water refining agent, soil mixture, cement and aggregate, and the resin is further densified. However, such a technique is still a technique that depends on the adhesion of the cement, it is almost ineffective in improving the environmental problems.
In addition, Patent No. 504987 describes soil reinforcement improving materials composed of admixtures such as fly ash or paper sludge, cement, pigment, slaked lime and silica fume in soil pavement construction. Patent Nos. 789877, 570958, and 581227. Many soil packaging patents, such as US Pat. No. 7,775,360 and the like, are a packaging technology that improves functions through additives to cement as described above.
Soil pavement is a paving material that people often use on the trails, parks, playgrounds, sidewalks, etc., it is preferable to use natural soil or environmentally friendly materials. In addition, natural damage or destruction for the construction of this packaging material is undesirable because it causes secondary environmental pollution. In addition, the soil-only packaging is often damaged by rainwater, the alternative to the alternative material of cement is still insufficient.
Accordingly, an object of the present invention is to solve the disadvantage that the packaging material using only soil is easily damaged, and to provide a durable earth packaging composition that does not use cement and is environmentally friendly and does not harm the human body.
Another object of the present invention is to provide a soil paving composition which neutralizes or weakly alkalizes an acidic soil by a soil paving composition and minimizes destruction of the natural environment.
Another object of the present invention to provide an environmentally friendly earth paving method using the composition of the above object.
In order to achieve the above objects as well as other objects that can be easily expressed, in the present invention, 50 to 90% by weight of soil such as masato, loess, clay, and surface soil of mine,
The soil pavement according to the present invention can suppress the emission of CO 2 gas generated during cement production due to the use of cement, not only can reduce the cost of CO 2 generation by the Kyoto Protocol, but also reduce air pollution, cement As it can block the occurrence of toxic Cr 6+ at the source, it can provide a pleasant environment not only to people using the paved road but also to the installers or neighboring residents without causing environmental pollution. The effect of soil pavement can be obtained.
The soil paving composition according to the present invention is 50 to 90% by weight of soil such as masato, loess, clay, surface soil of mine, and
In addition, the soil pavement method according to the present invention is 50 to 90% by weight of soil such as masato, ocher, clay, surface soil of mine, and
Soils used in the present invention are generally clays such as red mud (red clay) and ocher obtained from the surface of the earth, and sandy soils such as kaolin, white clay and masato, etc., and the type of soil is not particularly limited, but generally, It is preferable that the silt component having a particle diameter of 0.8 to 0.005 mm and the particles of fine granules and granules are suitably mixed in a ratio of 30%: 40%: 30%. In particular, in the present invention, the surface soil generated from the silica mine is mixed with the characteristics of various clay particles. The surface soil has a particle size of less than 212㎛ (average particle diameter is 50㎛) has a range of 30 ~ 50wt%, particles of more than 212㎛ ~ 2mm ranges from 50 ~ 70wt%, the viscosity and sand mixed properly There is a characteristic.
The mineral powder in the binder is C 5-81.7%, O 20-86.7%, Mg 1-67.7%, Al 1-67.7%, Si 3-69.7%, S 0.5-67.2%, Cl 0.5-67.2%, Ca 2- 68.7%, 0.1 to 66.8% of Ti, 0.05 to 66.75% of Mn, 0.05 to 66.75% of Fe, and one having an element composition ratio of In 0.1 to 66.8% are used.
It is preferable to use a mineral powder that does not contain heavy metals that harms the human body, and may contain trace elements in addition to the above components, and some of the above components do not contain or are substituted with other components. Also available. In addition, the elemental composition ratio of the mineral powder is not particularly limited, but C, O, Mg, Al, Si, S, Cl, and Ca must be included, and although the function of each element is not clearly identified, the above elements When each of these is not contained, the effect by this invention cannot be acquired.
The mineral powder is effective to use a particle size of 200 ~ 325 mesh (mesh), when the particle size is less than 200 mesh, there is a problem that the strength of the soil pavement to be constructed is not satisfactory, and when it exceeds 325 mesh It is not economical because manufacturing costs are rising.
Meanwhile, alkali metal chlorides and alkaline earth metal chlorides refer to chlorides of Li, Na, K, Rb, Cs, Si, Al, Fe, Ca, Na, K, and Mg, and at least one of them should be used and clustered. The mineral particles form a colloidal solution by the purified water, and the formed colloidal solution combines with the minerals of the mineral powder to exhibit a function as a binder.
Normally, water is composed of about 35 water molecules, forming a very large cluster. When sulfur dioxide, carbon dioxide, carbon monoxide, and chlorine gas are dissolved in water, they are not only entangled between clusters of water molecules but also entangled. As it is dissolved in water, sulfuric acid, sulfurous acid, carbonic acid, and hydrochloric acid are acidified, and toxic heavy metals such as mercury, lead, cadmium, and aluminum are entangled in clusters. Such a large water cluster containing gas streams or toxic metals to acidify the water not only has a harmful effect on the human body, but also causes a decrease in the binding force in the present invention, thereby preventing the effect to be obtained in the present invention.
Therefore, in the present invention, the clusters of water molecules are subdivided into 5-6 molecules through far-infrared radiation, magnetization, ultrasonication, etc. in the range of 4-14 μm to blow toxic gases entangled between the clusters of water molecules into the air. Heavy metals are precipitated using clustered water with supernatant only.
The clustered water can be prepared by a variety of known methods, it is preferable to use a stabilized by a known stabilization method, there is a problem that the binding force of the binder is lowered when using the non-clustered water in the present invention.
At least one compound selected from the group consisting of alkali metal chlorides and alkaline earth metal chlorides is added to the clustered water for dissolution. At this time, the amount of the at least one compound selected from the group consisting of alkali metal chlorides and alkaline earth metal chlorides is effective to use the amount of 1 to 60% by weight based on the weight of the clustered water, alkali metal chloride and alkaline earth metal When at least one or more compounds selected from the group consisting of chlorides are used in less than 1% by weight, there is a disadvantage in that the binding strength with mineral components derived from the mineral powder is lowered. Weak
A liquid binder is prepared in which water containing a small amount of rare earth elements and a pH adjuster are mixed in a solution in which alkali metal and / or alkaline earth metal chlorides are dissolved in clustered water.
Rare earth elements include lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, turlium, yttbium, ruthenium, scandium, yttrium, etc. Also available. Water containing a small amount of rare earth elements functions as an adjuvant of alkali metals and / or alkaline earth metal chlorides, and at the same time, functions to easily combine minerals and colloidal solutions by sterilization and bacteriostatic action. The content of the rare earth element is effective to use less than 1% by weight based on the total weight of the clustered water, and even in the water containing the rare earth element, water is used as the clustered water.
On the other hand, by using a pH adjuster in the liquid binder to be prepared to make the pH of the product produced is slightly alkaline, the amount of the pH adjuster can be appropriately adjusted according to the required pH.
The liquid binder and the mineral powder prepared as described above are mixed in amounts of 10 to 90% by weight, respectively, to prepare a binder composition for soil packaging. If the liquid binder is less than 10% by weight or the mineral powder is more than 90% by weight, there is a disadvantage that the strength of the soil pavement to be constructed is low, the curing time is long, and the liquid binder is more than 90% by weight If the mineral powder is less than 10% by weight, the strength of the soil pavement is improved, but there is a problem that the construction is not easy.
When the liquid binder and the mineral powder are mixed, the condensation and hardening occur rapidly, so it is preferable to mix immediately before use.
Preparing an earth packaging composition configured as described above; Laying the soil paving composition on a substrate; Compacting using a vibrating roller or a compactor; On the pavement surface, a curing device with a heating device such as an electric blanket is installed and cured or cured by natural curing to perform soil pavement construction.
In the soil pavement construction method using the soil pavement composition of the present invention, the soil pavement composition may be blended according to the above-described composition ratio of dry, semi-dry and wet.
The soil preparation composition preparation step, laying step, compaction step is a method that can be uniformly and completely construction of the soil packaging, is not particularly limited, can be applied by selecting a method commonly used in the art to which the present invention belongs. have.
Curing of the surface layer after the compaction in the soil pavement construction using the soil pavement composition is cured at a temperature of 25 ~ 80 ℃, natural curing is possible in the summer season, but in the period except summer season to promote hardening for fast walking and passage In order to cover the surface layer using commercially available curing cloth or vinyl, it can be cured by using steam or hot air, and more preferably, drying mats (roller type, far-infrared rays) sold by Century Century Co., Ltd. Using a film for heating 80 ℃ heating) can be kept warm for 4 hours or more at 60 ℃ to enable walking after 1 day.
The mechanism of soil pavement construction using the soil pavement composition of the present invention is not clear, but the minerals and the clustered water are strongly combined with the soil to exhibit high strength as well as the soil pavement only without the use of cement or synthetic resin. Construction is possible.
In other words, strong binding force is exerted by the reaction of dissolving → aquasol formation → condensation → gel formation → crystallization in the cloted water. It blocks the harmfulness of the existing cement, and can obtain a pavement base of 10 ~ 30MPa compressive strength.
1 is a schematic diagram illustrating the mechanism of action during construction of the soil pavement according to the present invention.
