Percentage increase in UCS versus different percentages of cement and silica fume (
after
Kalantari
et al.
, 2010).
Figure 7.17 shows the increase in UCS values for different percentages of cement
and silica fume. Similarly, it was observed that the CBR values of stabilized soil
increased, and the percentage increase in CBR is shown in Figure 7.18.
Different types of UCS test samples, made of fibrous peat that had a moisture
content of 187% and various amounts of OPC (5, 15 and 25%) and SFU (5 and 10%)
were prepared, and then air cured for up to 90 days. UCS tests were then conducted
for stabilized samples. Soaked UCS tests were also conducted on 90 days air cured
samples by submerging them in water for seven days prior to being tested as soaked
samples. The results are shown in Figure 7.19.
