183 | METHOD AND APPARATUS FOR RECOVERING VALUABLE METALS FROM SLAG AND FOR PRODUCING MULTIFUNCTIONAL AGGREGATES | EP10841100.0 | 2010-06-25 | EP2471963A1 | 2012-07-04 | KI, Joonseong; HWANG, Jinill |
Disclosed is a method and apparatus for recovering valuable metals from slag and manufacturing multifunctional aggregate, wherein a reductant is fed into molten slag discharged into a slag pot or a slag reforming pot from a converter or an electric arc furnace thus recovering valuable metals from the molten slag, and the molten slag from which the valuable metals have been recovered is formed into a lightweight porous structure. Accordingly, the valuable metals (Fe, Mn) are recovered from the slag discharged from the converter or electric arc furnace, and slag having low specific gravity is ensured using foaming and controlled cooling and then formed into multifunctional aggregate. This multifunctional aggregate is advantageous because its composition can be changed to be adapted to make cement, and because of decreasing the use of fuel upon making cement, saving power consumption, lowering CO2 emission by about 40%, exhibiting superior chemical resistance and high penetration resistance to chloride ions, and usability as cement material of concrete constructions having high durability. |

186 | LOW EMBODIED ENERGY WALLBOARDS AND METHODS OF MAKING SAME | EP08850384.2 | 2008-11-13 | EP2220010A2 | 2010-08-25 | SURACE, Kevin; WARE, Meredith; HOOVER, Denise; HAN, Jiaping; CHEN, Tiandan |
Wallboards, as well as other building materials, are produced by methods which use significantly reduced embodied energy, generating far less greenhouse gases when compared with the energy used to fabricate gypsum wallboard. A novel cementitious core, consisting in one embodiment of post-industrial waste such as slag and combined with pH modifiers, provides a controlled exothermic reaction to create a gypsum- wallboard-like core which can be wrapped in a selected material such as recycled paper and manufactured on a conveyor system to appear, weigh and handle similar to gypsum wallboard, but without the large amounts of energy required to make gypsum wallboard. The manufacturing process results in lower greenhouse gas emissions than the processes used to make gypsum wallboard. | ||||||
187 | PROCESS FOR PREPARING A FILLER FOR ASPHALT OR CONCRETE STARTING FROM A SLAG MATERIAL | EP08760359.3 | 2008-06-02 | EP2160367A1 | 2010-03-10 | NGUYÊN, Evelyne; VAN MECHELEN, Dirk |
The present invention relates to a process for preparing, starting from a slag material, a filler for construction materials which contain bitumen or a hydraulic binding agent. The slag used to prepare the filler contains y- dicalcium silicate. The process comprises the step of removing from the slag material a finer fraction formed by particles of a size between 0 and at least 0.75 mm so as to reduce the γ-dicalcium silicate content of the slag material; and the step of finely milling at least a portion of the remaining coarser fraction of the slag to obtain the filler. The invention also relates to the obtained filler, to the use thereof for preparing construction materials and to concrete or mortar compositions and asphalt compositions containing the filler. By removing the finer fraction from the slag material, a filler is obtained which has a considerably lower water content so that it becomes suitable for use in asphalt or concrete or mortar compositions, in particular in self-compacting concrete compositions. | ||||||
