Dear Sir/Madam,
In practice we usually determine the percentage of cement to use to produce a certain strength in MPa for different type of soil(stabilised layers).The test results are then plotted i.e compressive strenth against percentage of cement used.It is possible to plot the compressive stregnth againt degree of compaction by the use of dry densities of the stabilised materials and the maximum dry densitied of the stabilise layer?Is it a practical evaluation of degree of compaction of certain stabilised layer?????

Keep in mind that once the cement sets up, the compaction curve doesn't mean much anymore. In fact, the density can actually change during the hydration process.
You can plot dry density vs. cement content. That is useful to help in optimizing the cement content.
