摘要
铁尾砂是铁矿开采环节的主要固废,其堆放占用土地、影响环境,并威胁附近居民安全。经对铁尾砂碎石混合料采用无机水硬性固化剂稳定后,用于路面基层并进行了试验研究,包括抗压强度、间接抗拉强度和抗冻融性能等,进而分析了无机结合料稳定铁尾砂碎石的适用范围。
Iron tailings are the main solid wastes during iron ore mining.The piling up of iron tailings occupy land and affect the environment,and also threaten the safety of residents nearby.After stabilized by the inorganic hydraulic curing agent,the iron tailing gravel mixture can be used for the pavement base.The experimental study is carried out including the compressive strength,indirect tensile strength and freeze-thaw resistance,and then the scope of application of stabilized iron tailing gravel with inorganic binder is analyzed.
