The author describes the use of quick lime (CaO, calciumoxide) for treating wet earthworks. By mixing between 2 and 5 percent of quick lime with a very wet clay soil, the soil is stiffened up sufficiently to enable plant to traverse it and handle it. The treatment causes an increase in strength by reducing moisture content and by the reaction of the lime with soil. The effectiveness depends on the organic content, the proportion of clay and the clay mineralogy, among other factors, and preliminary tests are advisable. The geotechnical and drainage conditions should also be studied before it is decided to use the technique. Quick lime can be dangerous if not treated correctly, and operatives should wear protective clothing. Although the use of quick lime for treating wet earthworks is new in Britain, it has been extensively used in other countries for some years. /TRRL/
