摘录: 综述赤泥的化学和矿物构成,驾驭赤泥制备矿渣水泥、硅酸盐水泥、硫铝酸盐水泥等的商讨。指出以赤泥为原料制备水泥,因铝矿着手不同而导致赤泥化学组分不雄厚,增多赤泥配制水泥生料的难度;赤泥中氧化铁及碱金属含量较高,易导致配制的水泥生料熔融,增多反转窑结圈以致堵塞风险;生料中碱金属含量过高会导致预热器结皮,易导致水泥硬化体泛碱,裁减赤泥在水泥制备时的驾驭率。以为驾驭赤泥制备水泥,是处理赤泥的一条灵验阶梯,合乎可抓续发展计谋,具有邃密的经济效益、环境效益和社会效益;赤泥制备水泥仍须不停进行科研翻新,确立新赤泥驾驭阶梯,已毕赤泥的高效资源化驾驭。

谬误词: 赤泥;矿渣水泥;硅酸盐水泥;硫铝酸盐水泥

Abstract:Chemical and mineral compositions of red mud,as well as preparation of slag cement,Portland cements and sulphoaluminate cement were reviewed.It is pointed out that when red mud is used to prepare cement,different sources of aluminum ore can lead to unstable chemical compositions of red mud and increase the difficulty of raw cement preparation.The content of ferric oxide and alkali metals in red mud is high,which easily leads to melting of raw cement,and increases the risk of ring formation and even blockage of rotary kiln.High content of alkali metal in raw materials will lead to preheater crust,easily lead to cement hardening body pan alkali,and reduce the utilization rate of red mud in cement preparation.It is considered that using red mud to prepare cement is an effective way to deal with red mud,which is in line with the policy of sustainable development and has good economic,environmental,and social benefits.In order to realize efficient utilization of red mud,it is necessary to carry out scientific research and innovation in the preparation of cement from red mud.

Keywords:red mud;slag cement;Portland cement;sulphoaluminate cement
