Variables controlling strength of lime stabilized jarosite waste
Abstract 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 (qu) and split tensile strength (qt)] 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 qu and qt 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 qu and qt and L and t was possible by fitting the power function on the outcomes. Furthermore, a unique relationship between qu and qt is also developed, which is independent of L and t (i.e. qt/qu = 0.16).
