Abstract

Disclosed are a sorbent produced by recycling waste paper, which is an eco-friendly recycling paper resource, to adsorb and remove a marine spilled oil and other types of oil and a method of producing the same. The oil sorbent is produced by hydrophobizing a biomass material such as waste paper using a gas-grafting method. Compared to the oil sorbent of the prior art formed of synthetic resin, it is possible to provide excellent oil adsorption selectivity, a high oil adsorption rate, and a low water absorption rate. Therefore, an incineration process for processing the waste oil sorbent after use is easy advantageously. The oil sorbent generates less harmful substances during combustion because the eco-friendly material is used. Since a biomass material is hydrophobized using vegetable fatty acids, decomposition is performed fast within a short time in a landfill process, and there is no risk of environmental pollution.

Abstract

Disclosed is a variable-size sampling method under a data-streaming environment, including: calculating a maximum window size that satisfies a lower limitation of a predetermined uniformity confidence level at all times; inputting a data stream to be sampled; comparing a data stream length input until a current time point with the maximum window size; inspecting a sample size and a sampling fraction if the maximum window size is larger than the data stream length; performing sampling by generating a slot to increase the sample size if the current sample size is smaller than a predetermined percentage (P %) of the data stream; and directly performing sampling without generating a slot if the current sample size is equal to or larger than the predetermined percentage (P %) of the data stream. As a result, degradation of uniformity confidence during variable-size sampling under a real-time streaming environment can be prevented to improve sampling performance.

Abstract

Provided is a method of manufacturing a high-purity lithium phosphate by utilizing a lithium waste liquid of a wasted battery. Lithium phosphate is manufactured and refined by using a minimized amount of sodium hydroxide and by using phosphate, lithium hydroxide, and an optimized pH condition, so that it is possible to manufacture high-purity lithium phosphate from which fine impurities which cannot be removed by cleaning are effective removed. A waste water treatment process of processing waste water as to be immediately discharged is integrated, so that the method is very efficient and environment-friendly. Therefore, since the high-purity lithium phosphate can be manufactured by utilizing a lithium waste liquid discarded in a wasted battery recycling process, the method has an effect in that the method is applied to a wasted battery recycling industry to prevent environmental pollution and facilitate recycling resources.

Abstract

The present invention relates to an apparatus for producing rapid-hardening concrete and a method for producing same, the rapid-hardening concrete being produced by intermixing and dissipating air in normal concrete and adding an early-strength admixture thereto. With respect to forming rapid-hardening concrete, mixed concrete is formed by mixing in a large volume of air bubbles to be discarded, along with an early-strength admixture, to already mixed normal concrete, the early-strength admixture getting evenly dispersed therewithin by means of the ball bearing effect of the air bubbles, and when the mixed concrete is discharged, a rapid-hardening concrete is shotcreted while excess air contained in the mixed concrete is dissipated by means of high-pressure air, the slump which was raised due to the large amount of air bubbles having been reduced to the slump range for normal concrete.

Abstract

The present invention relates to a method for producing a hybrid concrete by after-addition and mixing of foamed fine-pozzolan slurry and latex, wherein a foamed fine-pozzolan slurry, which is an inorganic substance, is admixed into a normal concrete obtained by mixing cement, water and aggregate so as to form an admixed concrete, and latex or a water-soluble polymer and an acrylic polymer, which is an organic substance, is mixed into the admixed concrete so as to form a remixed concrete which, when discharged by a shotting guide member, is blown using compressed air at a high pressure of at least 5 atmospheres such that the air comprised in the remixed concrete is dissipated as the air content is adjusted to between 3 and 7%, and a hybrid concrete having a slump of about 100 to 200 mm is produced. Accordingly, it is possible not only to substantially economise on construction costs by reducing the amount of latex which is generally incorporated, but also to ensure high strength and high durability of the hybrid concrete by blowing the remixed concrete, when discharging the same, using the compressed air at the high pressure of at least 5 atmospheres and thereby dissipating the air comprised in the remixed concrete such that the air content is adjusted to between 3 and 7% and the hybrid concrete has the slump of about 100 to 200 mm.

Abstract

The present invention relates to an apparatus and a method for manufacturing high performance concrete capable of manufacturing high performance concrete through the processes of inserting air into normal concrete and dissipating the air. In order to form high performance concrete, the apparatus and method of the present invention: insert a large amount of bubbles, which are supposed to be removed, to normal concrete, which has already been blended, along with mixed materials; and form mixed concrete by evenly dispersing and mixing the mixed materials in the normal concrete using the ball bearing effect of the bubbles. Furthermore, the apparatus and the method of the present invention discharge the mixed concrete using air of a high pressure not lower than 5 atm, to thereby shoot high performance concrete of which the slump, drastically increased due to the large amount of bubbles, is reduced to the range of the slump of the normal concrete, while dissipating excessive air contained in the mixed concrete.

The present invention relates to complex floating wetland equipment including an otter habitat, a land area, an inclined plane, a first underwater spawning ground, a second underwater spawning ground, and a perch. Thus, otters and birds may sufficiently obtain prey, and fish may access spawning grounds having adequate spawning characteristics. As a result, otters, fish, and birds may cohabitate together. Also, the complex floating wetland equipment may include a frame that is manufactured by using only wood for providing buoyancy or by using stainless steel for strength reinforcement and wood for providing buoyancy, in which case a small amount of polyethylene foam may be required. As a result, the complex floating wetland equipment may be simplified in structure. In addition, the wood frame itself may provide the spawning grounds for fish.

The present invention relates to a method for constructing a bobsleigh course using a high-performance wet-type shotcrete composition, and more particularly, to a method of constructing a bobsleigh course that uses a high-performance wet-type shotcrete composition which includes silica fumes and AE material, and which has increased pumpability prior to being deposited due to the presence of a superabundant amount of air, and increased shootability after being deposited since the amount of air present is decreased, thus imparting high constructability, high strength, and high durability to the composition. To this end, the method comprises: a framework-forming step of fixing a wire-mesh formwork, positioning a cooling pipe, strengthening adherence and holding strength, and installing a curvature-maintaining pipe; a shotcrete-laying step of laying the shotcrete composition; a first surface-finishing step of setting a curved surface and performing finishing using plastering; a second surface-finishing step of performing a rough surface finishing; and a wet curing step of performing wet curing.
