The study advocates the influence of lime (L) and curing period (t) on stabilization of jarosite waste. A number of laboratory strength tests [unconfined compressive (q_u) and split tensile strength (q_t)] are conducted on artificially cemented jarosite-lime blends (lime = 2.5–10%) with different curing periods (t = 7, 28 and 90 days). The outcomes indicate that both q_u and q_t increase nonlinearly with the increase in lime content and curing period, which is further justified by microstructural study that illustrates the occurrence of larger agglomeration in particles. In addition to these, a good correlation between q_u and q_t and L and t was possible by fitting the power function on the outcomes. Furthermore, a unique relationship between q_u and q_t is also developed, which is independent of L and t (i.e. q_t/q_u = 0.16).

控制石灰稳定的黄钾铁矾废料强度的变量

该研究主张石灰（L）和固化时间（t）对黄钾铁矾废物稳定化的影响。许多实验室强度测试[无侧限抗压强度（q _u）和劈裂抗张强度（q _t）]是在不同固化时间（t = 7、28和10）的人工胶结的黄钾铁矾-石灰混合物（石灰= 2.5-10％）上进行的。 90天）。结果表明，q _u和q _t均随石灰含量和固化时间的增加而非线性增加，这通过微观结构研究进一步证明是正确的，该研究表明了颗粒中发生了较大的团聚。除了这些，q _u和q _t之间的良好相关性L和t可以通过将幂函数与结果拟合来实现。此外，还建立了q _u和q _t之间的唯一关系，该关系独立于L和t（即q _t / q _u  = 0.16）。
