4Question 4.
True or False: Chemical stabilization can only be achieved with cement.
- True
- False
Show hintHide hint
Think about the diverse materials used.
Question 5.
You have a natural soil with a UCS of 150 psi. You add 5% lime, curing it as per specifications. After evaluation, your UCS is 210 psi. Is this stabilization successful?
Show hintHide hint
Calculate the gain and compare it to the threshold.
Question 6.
A project requires evaluating the cost-effectiveness of using fly ash as a stabilizer versus traditional cement. Consider the properties, environmental impact, and overall strength needed.
Show hintHide hint
Compare both in terms of technical and financial perspectives.
