"As a study of all types of stabilization would be very lengthy, it was decided to make the object of this research the determination of the effect of the addition of different percentages of calcium oxide (CaO) and calcium hydroxide Ca(OH)2 on the physical characteristics of a silty swelling sodium montmorillionite clay. The purpose of this addition is to flocculate the clay by utilizing a base exchange between the sodium and calcium ions, and thus change the physical characteristics of the soil. The soil by itself has the characteristics of a fat clay, that is it can be broken but not crushed or pulverized by hand; when partially dried the material is plastic but very hard to remove from one's hands, also cohesion is pronounced in such soils.
The physical properties of the soil were determined by performing certain laboratory tests. Then calcium hydroxide and calcium oxide was added separately to the soil in the amounts of 2, 4, 6 percent. Alter the previously mentioned addition the laboratory tests were repeated and changes in the soil characteristics observed. The properties chosen for comparison were: Liquid Limit, plastic limit and subsequently the plasticity index; shrinkage limit; shrinkage ratio; unconfined compressive strength; cohesion and angle of internal friction"--Introduction, page 3.
