94Single Piers of Various CompositionStress-SettlementSingle piers tested at this stage were constructed of cement, loess and aggregate piermaterials as a main component, as well as, other mixture constituents as outlined in Table 19.Stress-settlement results were plotted and grouped by length and the tell-tale information wascollected as well. The results were supplemented with pier profile images and are provided inFigure 59 through Figure 70.Applied stress at top of pier (kPa)00 500 1000 1500 2000 250024Settlement (mm)681012Top14Figure 59: Stress-settlement test results for(a)matrix soil used for placement of singlepiers of various compositionApplied stress at top of pier (kPa)00 500 1000 1500 2000 250024Settlement (mm)68
