高炉矿渣是炼钢过程中的副产品，是一种独特的水硬性材料。介绍了一种利用矿渣作为水硬性材料的泥浆转水泥新工艺，并简要评述了这种矿渣混合料的技术优点。该技术在经济、技术和环境方面均上级传统波特兰水泥，已在许多领域得到应用，主要的环境效益是减少了泥浆排放量。自从在墨西哥湾的前景螺旋钻应用矿渣混合物以来，过量的全泥浆排放量减少了约70%（每口井4，530桶）。大约15，000桶多余的钻井泥浆在Auger回收到矿渣混合物中。此外，开发了一种新的钻井废物管理方法，以减少或消除钻机现场的钻井废物。一种含40 ~ 60磅/桶矿渣的新型加渣钻井液能产生随时间自凝的含渣岩屑。原位固化方法似乎是环境可接受的，并具有潜在的成本效益。
Blast furnace slag is a unique hydraulic material which is a by-product of the steel-making process. A new method of mud to cement conversion technology utilizing slag as the hydraulic material has been developed, and the technical merits of this slag mix are briefly reviewed. This slag mix technology is economically, technically, and environmentally superior to conventional Portland cements and has been used in many fields.The major environmental benefit is the reduction of mud disposal volume. Since the application of slag mix at Prospect Auger in the Gulf of Mexico, excess whole mud discharge has been reduced by about 70% (4,530 barrels per well). Approximately 15,000 barrels of excess drilling mud was recycled into slag mix at Auger.In addition, a new drilling waste management method to reduce or eliminate drilling waste at the rig-site has been developed. A new type of slag-supplemented drilling fluid containing 40 to 60 lb/bbl slag can produce slag-laden cuttings which are self-setting with time. The in-situ solidification method seems to be environmentally acceptable and potentially cost-effective.
