Problem 1.7 The following results were obtained from a standard compaction test on a soil. The value of G, is 2.67. Plot the dry density-water content curve, and give the optimum water content and maximum dry density. Plot also the curves of zero, 5% and 10% air content, and give the value of air content at maximum dry density. The volume of the mould is 1000 cm'.
