    摘要： In a method for the production of high-strength, acid-resistant concrete by use of water, hydraulic binder and aggregates, a hydraulic binder containing aluminosilicates, calciumsulfate and an activator containing salts of alkalimetals is applied wherein the aluminosilicates are chosen from the group consisting of furnace slag, clay, marl and industry-by-products like flue-ash with the requirement that the Al2O3-content of the binder is greater than 5% (w/w) and that furnace slag is present in an amount less than 35% (w/w) of the binder and that cement kiln dust in amounts from 1 to 20% (w/w) of the binder is applied as activator whereby the hydraulic activator is applied in amounts >400 kg per m3 concrete safeguarding a water/binder ratio from 0.25 to 0.40.

    摘要： A process for the production of Portland cement and white Portland cement using magnesium furnace slag, a waste product from the manufacture of magnesium metal, as a primary starting material. The furnace slag is blended with calcium oxide and silicon dioxide to form a feedstock which is heated to a temperature and for an amount of time sufficient to form clinker. The clinker is cooled, ground to a powder, and blended the clinker with powdered gypsum to form the Portland cement. White Portland cement may be produced by removing iron containing compounds from the slag, minimizing contamination of the material by iron compounds throughout the process, and cooling the clinker in a manner that minimizes oxidation of any remaining iron compounds in the clinker.

    摘要翻译： 使用镁炉渣生产波特兰水泥和白色硅酸盐水泥的工艺，一种来自镁金属制造的废品作为主要原料。 炉渣与氧化钙和二氧化硅混合以形成原料，将其加热到足以形成熟料的温度和一定的时间。 将熟料冷却，粉碎成粉末，并将熟料与粉状石膏混合以形成波特兰水泥。 可以通过从炉渣中除去含铁化合物来生产白色硅酸盐水泥，使整个过程中铁化合物对材料的污染最小化，并以最小化熟料中剩余的铁化合物氧化的方式冷却熟料。
