Controllable low-strength material prepared from iron ore tailing mud and preparation method
The invention provides a controllable low-strength material prepared from iron ore tailing mud and a preparation method thereof, and is characterized in that the controllable low-strength material comprises the following components in percentage by mass: cement clinker accounting for 6%-8% of the mass of the iron ore tailing mud, a naphthalene water reducer accounting for 1.5% of the mass of the iron ore tailing mud, 48%-52% of the content of the iron ore tailing mud, and 42%-46% of the water content. According to the invention, the iron ore tail mud is used as the aggregate, so that the mixture can meet the design and excavation requirements of foundation bearing capacity, has high fluidity and controllability, has high economic benefits and is environment-friendly, and an effective new way is provided for solving the problems that the iron ore tail mud is non-uniform in grading, solid waste materials are difficult to effectively utilize and the like.
本发明提供了一种利用铁矿尾泥制备可控性低强度材料及制备方法，其特征在于，包括以下质量百分含量的各个组分：水泥熟料含量为铁矿尾泥质量的6%～8%、萘系减水剂掺量为铁矿尾泥质量的1.5%，铁矿尾泥含量48%～52%，含水率42%～46%。本发明提出使用铁矿尾泥作为骨料，使混合料能满足地基承载力设计开挖要求，其具有高流动性、可控性，具有经济效益高和环境友好型，为解决铁矿尾泥级配不均匀和固废材料难以有效利用等问题提供了一种有效新途径。
