Figure 24(a) shows modulus of elasticity(Esso) of unsoaked samples against curing time. In the early stage(after mixing to 28 days), Mix-1 and Mix-3 rapidly gain in Eso. The modulus of elasticity seems to be uniform at long curing periods. On the other hand, Mix-2, and Mix-4 steadily gain in density over curing periods. In addition, Eso changes orderly based on mixing cement content, i e. Mix-1 is higher than Mix-2, Mix-2 is higher than Mix-3, etc. These results also conformed to strength development characteristics and density of treated soils as discussed previously.
