美国伯克利市加利福尼亚大学的梅达权教授发明了一种既节省能源又吃工业废料的新型水泥——高铁水硬水泥,并获得该水泥的专利权。这种水泥以粉煤灰或者钢渣、赤泥、硫酸盐污泥等为原料。高铁水硬水泥的氧化钙含量比通常降低了25％,但增加了5—20％的氧化铁和10％
Prof. Mei Daquan of the University of California, Berkeley, USA, invented a new type of cement, high-strength cement that saves energy and eats industrial waste, and obtained the patent for the cement. This kind of cement uses fly ash or steel slag, red mud, and sulphate sludge as raw materials. The content of calcium oxide in high-strength hydraulic cement is usually reduced by 25%, but it is increased by 5-20% of iron oxide and 10%.
