摘要： Possible emission of hydrogen sulphide from building materials incorporating a sulphide-containing constituent, for example ground blast furnace slag, can be suppressed or prevented by the application of a surface covering composition containing gypsum plaster and a metal compound capable of reacting with hydrogen sulphide to form a stable sulphide. It is preferred that the metal compound should have no substantial effect on the setting rate of the gypsum plaster, and may for example be an insoluble compound, while it is also preferred that the sulphide should be colorless and insoluble. Preferred metal compounds are zinc compounds and especially zinc oxide. Surface covering compositions for the purposes of the invention may contain from 0.01 to 1% by weight of the metal compound. The sulphide-containing constituent may be in a building structure or may itself be contained in a surface covering composition of rendering. In such a composition or rendering, blast furnace slag or other pozolanic or latent cementitious materials, have the advantage that they afford rapid surface drying while retaining advantages of rapid and controllable set. The risk of hydrogen sulphide emission under wet conditions is avoided by the invention. The metal compound may be included in the same composition as the sulphide-containing material, for example in a composition comprising by dry weight 20 to 84% gypsum plaster, 15 to 79% sulphide-containing aggregate, and 0.01 and 1% metal compound. Alternatively, the metal compound may be included in a finishing material comprising 97.8% to 99.9% gypsum plaster, up to 2% lime and 0.05 to 0.2% zinc oxide. The latter composition may also be applied to the surface of building structures including sulphide-containing components, for example building blocks containing blast furnace slag.
摘要翻译：通过施加含有石膏膏和能够与硫化氢反应的金属化合物的表面覆盖组合物，可以抑制或防止含有含硫化物成分（例如磨碎的高炉矿渣）的建筑材料中的硫化氢的排放，形成稳定的硫化物。优选的是，金属化合物对石膏膏的凝固速度没有显着影响，例如可以是不溶性化合物，而硫化物也优选为无色和不溶性。优选的金属化合物是锌化合物，特别是氧化锌。用于本发明目的的表面覆盖组合物可含有0.01至1重量％的金属化合物。含硫化物的组分可以是建筑结构，或者本身可以包含在表面覆盖组合物中。在这种组合物或成型工艺中，高炉矿渣或其他pozolanic或潜在的水泥质材料具有这样的优点：它们提供快速的表面干燥，同时保持快速和可控制的优点。本发明避免了潮湿条件下硫化氢排放的风险。金属化合物可以包含在与含硫化物材料相同的组成中，例如包含干重20至84％石膏膏，15至79％含硫化物骨料和0.01和1％金属化合物的组合物。或者，金属化合物可以包括在包括97.8％至99.9％的石膏膏，至多2％的石灰和0.05至0.2％的氧化锌的整理材料中。后一种组合物也可以应用于包括含硫化物的组分的建筑结构的表面，例如含有高炉矿渣的构件。

摘要： Sulfuric acid-containing coal mining refuse is reacted in the presence of moisture with lime, and preferably also with a pozzolanically active material such as fly ash, whereby the existing sulfuric acid is neutralized with lime and further reacted with lime and pozzolan to produce a non-polluting cementitious material, which is self-hardening at atmospheric pressure. This material may be used as structural fill or as a road base material. Alternatively, piles of such refuse may be treated so that a self-hardening mixture is formed either totally or on the surface thereof, thereby preventing further water percolation therethrough and resultant subsurface water contamination.

摘要： FLY ASH IS SUBJECTED TO A MAGNETIC SEPARATION TO REMOVE AN IRON CONCENTRATE PRODUCT. THE REMAINDER IS THEN SUBJECTED TO AIR CLASSIFICATION TO REMOVE A FINE POZZOLANIC MATERIAL WITH AT LEAST 85% OF THE PARTICLES BEING MINUS 325 MESH. THE REMAINING HEAVY ENDS ARE DRY SCREENED OVER A 100 TO 150 MESH SCREEN TO REMOVE A COARSE PRODUCT CONTAINING AT LEAST 25% CARBON. THE PRECISE DRY SCREEN SIZE IS SELECTED FROM THE RANGE OF 100-150 MESH TO MAINTAIN THE CARBON CONTENT IN THE -100 TO -150 MESH SINTER FRACTION WITH THE RANGE OF 5 TO 8%. THE SINTER FRACTION, IF NECESSARY, IS BLENDED WITH SUFFICIENT AMOUNTS OF POZZOLANIC MATERIAL TO REDUCE THE IRON CONTENT TO BELOW 10%, PELLETIZED AND SINTERED AT 1900*F. TO 2800*F.

摘要： A moist sludge as obtained from gases evolved during steel preparation in converters by blowing oxygen through said liquid steel is treated with 30% flue dust. Preferably the mixing is effected in two steps, in the first step 60% of the flue dust is added and the particles as obtained are mixed with the remaining flue dust in a second step without crushing the particles of the first step, particularly by using a whirling process.

摘要： A process and apparatus are disclosed for producing a cinder material useful as an aggregate in building materials such as building blocks or paving materials. The aggregate is produced from solid particles of waste, particularly bottom ash formed from the burning of coal in a power plant. Water is mixed as a vehicle with the bottom ash at the power plant to form a slurry, and the slurry is transported to a processing plant through a fluid conduit. At the processing plant the slurry is partly dewatered and excessive proportions of fine particles removed by passing the slurry through a baffled flume. Overside particles are removed from the slurry by passing it over a screen. The slurry is then fed into a screw classifier which separates out a solid particle component to provide a high quality cinder aggregate.

摘要： Cellular concrete structures are made by admixing water and cement under conditions sufficient to produce a high degree of hydration of the cement particles, followed by the introduction of a foam formed under pressure from a mixture of water, air, foaming agent and chloride accelerator. The foam mixture and cement admixture are blended to a substantially homogeneous, foamed cement slurry, which is cast into a mold and cured to form a lightweight cellular concrete structure. In the structure, the voids are relatively spherical in shape and have an average diameter of about 0.05 to 0.050 inch. The foaming agent and cure accelerator are concentrated at the surface of the concrete matrix about the voids, and the structure has a uniform density of about 25 to 75 pounds per cubic foot.
