Abstract:
The study advocates the infuence of lime (L) and curing period (t) on stabilization of
jarosite waste. A number of laboratory strength tests [unconfned compressive (qu) and
split tensile strength (qt
)] are conducted on artifcially cemented jarosite-lime blends
(lime=2.5–10%) with diferent 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 justifed 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 ftting 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)
