At a construction site, three deep soil$-$cement mixing test columns were

constructed in silty clayey $($DSM$\_1),$ sandy $($DSM$\_2)$ and gravelly $($DSM$\_3)$ soil

profiles. If the target shear strength of columns is defined as $510$kPa, estimate the

cement dosage required in to achieve this target for columass constructed in these three

different soil profiles.

Hint: Use Taki and Yang $(1991)$ chart to estimate the cement dosage along with the

comelation between unconfined compressive strength and shear strength by Saito et al$.$
