    摘要： The carbonate bonded, press-moulded article is produced by press-moulding a particulate, carbonatable material that contains water and by carbonating the obtained compact with carbon dioxide gas. In order to be able to ensure an optimal compressive strength of the article two types of tests are provided. In the first type of test a sample of the particulate material is compressed with an increasing compaction pressure and when water starts to be expelled from the material as from a particular compaction pressure, the press-moulding step is performed with a compaction pressure which is at least 7 MPa smaller than this compaction pressure. In the second type of test different samples of the particulate material are press-moulded with different compaction pressures and, after having released the compaction pressure, the density of the compact is determined. In case this density decreases instead of increases as from a particular compaction pressure, the press-moulding step is performed with a compaction pressure which is smaller than this particular compaction pressure.

    摘要翻译： 碳酸盐结合的压制成型品通过对含有水的颗粒状可碳化材料进行加压成型，并且用二氧化碳气化所得到的成形体来制造。 为了能够确保制品的最佳抗压强度，提供了两种类型的试验。 在第一种类型的测试中，颗粒材料的样品以增加的压实压力被压缩，并且当水从特定压实压力开始从材料中排出时，压制成型步骤以压实压力 比该压实压力小至少7MPa。 在第二种测试中，颗粒材料的不同样品被压制成不同的压实压力，并且在释放压实压力之后，确定压块的密度。 如果从特定的压实压力来降低密度而不是增加，则压制成型步骤以小于该特定压实压力的压实压力进行。

    摘要： Disclosed is a heavyweight concrete composition using slag byproducts, including: ground granulated blast furnace slag; slow-cooled electric-arc-furnace oxidizing slag or atomized steel slag used as a fine aggregate; a coarse aggregate; water; and a chemical admixture based on 100 parts by weight high-early-strength cement. Thus, the heavyweight concrete composition contains a large quantity of steel slag and blast-furnace slag that are byproducts in iron-making and steel-making processes, thereby remarkably reducing an amount of emission of carbon dioxide and maximizing the recycling of waste resources for preserving the natural environment. As a result, an eco-friendly heavyweight concrete product can be made.

    摘要： The invention provides a process for conversion of basic oxygen furnace slag into construction materials like hydraulic binder in masonry blocks, flat sheets, bricks and tiles and also as a blend in cement manufacture or as in mortar for various applications. A required quantity of fluorspar is added to the molten slag for increasing its fluidity and the mixture is allowed to cool. The slag is then crushed to -3 mm size and any metallic fraction is separated using a magnetic separator. The -3 mm size non-metallic slag is ground to about 3000-4000 blain depending upon the application for which it is required. A desired quantity of gypsum can be mixed with the non-metallic fraction of the -3 mm slag before grinding.

    摘要： A process for processing stainless steel slags, wherein these stainless steel slags are crushed to a particle size which is mainly smaller than about 60 mm at the most and wherein the crushed steel slags are processed further to produce a shape retaining mass containing the particles of the crushed steel slags in a bound state. The crushed steel slags are more particularly used for the production of asphalt. Due to the binding of the particles in this shape retaining mass, the problem of leaching, in particular of chromium, nickel and fluoride, is solved. Furthermore, it has been found that the crushed steel slags have a good cubicity and an equilibrated grain distribution for achieving asphalt with a high compression strength.
