One of the objectives of the present work was to investigate the effect of the change in dynamic energy on the compaction of soils. The energy was changed by altering; height of drop, diameter of striking face or weight of rammer. The film theory, advanced to interpret the compaction phenomena, has been, discussed in the light of the present work and led to the development of a new theory which is capable of interpreting all phenomena encountered in compaction. A general equation has been derived, and proved dimensionally, to determine the max. density of any type of soil compacted under dynamic energy, once the mechanical analysis and specific gravity of the soil are known. Another general equation has been derived to determine the optimum moisture content of any type of soil. An investigation, on the effect of compaction under static loads on tensile-strength, of Staines and Blue London Clays and Clayey Brickearth is given in, the course of this thesis. A new device was developed to measure the tensile strength as low as 2 lb/ Such investigations have shown that compaction increases the tensile strength of clays, which in turn increases with increase in compactive effort. The effect of the spent lye, from the paper industry, and hydrated lime on the compaction characteristics bios and stabilization of London Clay, has been investigated. The spent lye from the sulphite process reduces the capillary water absorption of the clay. Hydrated lime, which is cheaper than cement, is very effective in amounts of 10%, for the stabilization of London Clay. Furthermore, it implies higher strengths than that of cement and is a good waterproofing agent which maintains high strengths under severe conditions.
