TWI287582B - Improved basic oxygen furnace slag material with ability to inhibit swell again and leaching of heavy metals-Pozzolans addition - Google Patents

Abstract

The present invention is to provide a processing method for CSC byproduct, basic oxygen furnace slag, to reduce the leaching of heavy metals and swell again. The present invention uses Pozzolans method utilizing wet-binder method and substitution-wet-binder method to dilute, solidify, and chelate the basic oxygen furnace slag so as to stabilize the basic oxygen furnace slag. The wet-binder method and substitution-wet-binder method used in the present invention belong to Pozzolans addition. The rate of swell again and heavy metals are decreasing with the increasing addition amount of Pozzolans after calculating a series of data. Further, the control mode of the rate of swell again is calculated as Y=5.35X-0.507 and the control mode of the leaching of heavy metals is calculated as Y=729.81X-0.494, wherein Y represents the rate of swell again and the leaching amount of heavy metals respectively, X represents the addition amount of. Considering about the rate of swell again and the leaching amount of heavy metals at the same time, the result showed that the quality requirements of engineering and environment can be met by adding only 8%-50% of Pozzolans. As the leaching of heavy metals, the toxicity characteristic leaching, the leaching of soil contaminants, and the aqua regia digestion test are conducted showing that heavy metals such as chromium, cadmium, plumbum, arsenic, mercury, copper, zinc, nickel, etc., are lower than the control standard of leaching of heavy metals. As the rate of swell again is proceeded under the regulation of CNS 14602 (JIS A5015), the result shows that the rate of swell again is lower than 1.36% which is much lower than 1.5% of the requirement final rate of swell again defined in CNS 14602. The CBR value is more than 133.63% which exceeds in the quality requirement of CBR value for highway base. These results prove that basic oxygen furnace slag may obtain the effects of inhibiting the leaching of heavy metals, reducing the rate of swell again, increasing the shear strength, and improving the bearing-ratio after treatment and becomes excellent filling and construction material used for civil and architect engineering.

The present technology can reduce or deal with the goals of "reduction", "resources", and m-distribution, and therefore the technical field to which the present invention pertains. & Ma Tumu Recycled Materials (II), [Prior Art] Converter stone is a solid solution composed of various minerals, such as ash (f-CaO), magnesium oxide (Mg0), tricalcium citrate (CaS), tannic acid Dicalcium (QS), etc., these compositions have instability in the high-calculation slag, in which unreacted lime (f-CaO) hydration produces the largest volume expansion of calcium hydroxide, followed by MgO hydration. The volume of magnesium hydroxide will expand; usually the converter stone containing unreacted lime (f-CaO) and magnesium oxide (Mg〇) is in a stable state, and only when f-CaO and MgO are hydrated and dissolved, Stable ". Therefore, after the converter slag is on the scene, it is only used as a stacking yard. After the f~Ca〇 and Mg〇 are completely hydrated and dissolved, it can be used for other purposes. This is quite uneconomical, and it also creates the dilemma of no-stacking of the hearth and Waste of national resources.

As shown in Fig. 18, the mixture is uneven and the structure is melted. Is it a body-like mass? Soil (5): Hearthstone: Appearance is in the form of flakes, densely packed with fine pores, soil trapped in σ soil group, and divided into soil masses; Figure 19; (6) Riverbed fine grain mass / ice soil mass There are large pores such as • soil mass, the soil is tight and the soil is tight. The appearance is formed by laminating the sheet structure, and the σ is combined, as shown in Fig. 20.
