The maximum UCS value of the Ratmate soil is determined as 1314.04kPa when cured for 14 curing days
treated with 7% cement. In this case, the minimum UCS value was determined to be 555.69kPa when
treated with 3% cement content cured for the same 14 days. Also, the UCS value was increased up to
1265.68kPa with 5% cement content, but when cement was increased to 10%, UCS was decreased to
918.70kPa, as presented in Fig. 2 and Table 3 respectively.
The maximum UCS value of the Ratmate soil was found to be 1651.98kPa cured for 28 curing days when
treated with 7% cement. In contrary, the minimum UCS value was determined to be 617.48kPa when treated
with 3% cement cured for the same 28 days.

Also, the UCS value was increased up to 1506.06kPa with 5% cement content; however, when cement
content was increased up to 10%, UCS decreased to 1036.24kPa, as shown in Fig. 3 and Table 3
respectively. The strength obtained after 28 curing days shall be the ultimate strength for this research.
