That implies that demand for basic manufactured items such as steel, cement and copper wire will remain soft as developers slow construction of new projects. 这种局面意味着,随着开发商减缓了新项目的施工,对钢铁、水泥和铜线等基本制成品的需求将保持疲软。
To reduce the filling cost, various cement sand ratios are used at different heights for the tailings consolidated filling body in Anqing Copper Mine. 松散颗粒填充隔热层为了降低充填成本,安庆铜矿尾砂胶结充填体在不同的高度采用了不同的灰砂比。
The main destination for the stolen metal is China, whose booming economy has turned it into the world's largest consumer of copper, steel and cement, and which imports 80 per cent of its copper from producers such as Chile and Peru. 被盗铜金属的主要目的地是中国。蓬勃发展的经济已使中国成为全球最大的铜、钢铁和水泥消费国,其中80%的铜从智利、秘鲁等铜生产国进口。
It is the coming shortage of everything – cement, iron ore, coal, steel, lead, zinc, aluminum and copper. 这个事件便是我们未来即将面临的所有资源短缺&水泥、铁矿石、煤炭、钢铁、铅、锌、铝和铜。
Nowhere is this clearer than in raw materials such as steel, cement and copper, which are linked to construction and the cooling property market. 钢铁、水泥和铜等原材料行业受到的影响最为明显,这些行业与建筑业以及日益冷却的房地产市场息息相关。
The result shows that the burnability of cement raw meal with high content of C3S batching was improved with suitable content of phosphor slag, but the effect of copper slag and lead-zinc slag was not that obvious. 研究表明:铜渣、铅锌渣对改善高C3S配料的水泥生料易烧性效果不明显,掺入适量磷渣可很好地改善水泥生料的易烧性。
The Research on Super-high-strength, High Wearability Cement Mortar with the Incorporation of Copper Slag as Aggregates 铜渣集料超高强、高耐磨水泥砂浆研究
This paper studies the influences of copper tailings on the burnability of cement raw meal and on cement strength when copper tailings are used to replace iron cinders wholly and clay and limestone partly in the mix. 本文研究了利用铜尾矿全代铁粉和部分取代粘土、石灰石配料时,铜尾矿对水泥生料易烧性及水泥强度的影响。
This article describes the requirements of cement mill on grinding media and introduces the composition, property and metallographic structure of grinding balls containing chromium, copper and molybdenum. 本文分析了水泥磨机对研磨体性能的要求,介绍了铬铜钼磨球的成分、性能、金相组织。
Therefore, the optimization of the cement sand ratio of the filling body of Anqing Copper Mine is a very complex problem of nonlinear combined optimization. 因此,安庆铜矿充填体灰砂比的优化是一个十分复杂的非线性组合优化问题。
