摘要
针对当地工业固体质物现状,经过上百次试验和技术攻关,成功地将电厂废弃物脱硫石膏作为水泥的缓凝剂,完全取代了天然石膏。不仅节约了资源,同时防止过渡开采,保护了生态环境。
Based on the local situation of industrial solid material and hundreds of tests and technical research, the waste of power station can be successfully used as the cement retarder in place of the natural gypsum. This not only saves the resource and at the same time prevents over mining but also protects the ecological environment.
