埃塞俄比亚复兴大坝专用水泥的生产实践

Production practice of dedicated cement for Grand Ethiopian Renaissance Dam

针对埃塞俄比亚一条5600t/d水泥生产线,制定了复兴大坝专用水泥的标准。复兴大坝专用水泥先确保水泥水化热及强度等级,忽略水泥中碱含量成分,原材料选择石灰石、玄武岩、砂岩;水泥混合材使用浮石,以南非的烟煤为燃料。制订复兴大坝专用水泥配料方案,进行水泥试验,调整浮石配比。结果表明:生产的大坝专用水泥的强度、水化热等指标符合指标要求,质量稳定,安定性合格。

The standard for renaissance dam dedicated cement was developed for a 5 600 t/d cement production line in Ethiopia. re- naissance dam dedicated cement ignored the alkali content of cement components firstly to ensure cement hydration heat and strength level.Limestone, basalt and sandstone were used as raw materials; And cement mixture used pumice and South AfricaJs bituminous coal were used as fuel. The ingredients program of renaissance dam dedicated cement was formulated, the cement test, then carrying out cement test, adjust the ratio of pumice. The results show that the indicators such as strength ：and hydration heat of dam dedicated cement meet the requirements of the index, the quality is stable and the stability is qualified.
