Recent experiences with cement and lime - Stabilization of local typical poor cohesive soil
Clay soils notorlously provide a challenge to the geotechnical engineer due to their considerable variety in terms of composition and properties and in particular their variation in properties with time and loading. These 'unsuitable' materials generally require improvement before construction can take place above them. Improvement of the properties of such soils for construction purposes can be achieved by a variety of means; mechanical and/or chemical improvement or reinforcement by physical inclusion of tensile elements (e.g. geosynthetics). Some of these means are applied successful for thousands of years, and others are still in need of further research. Stabilization of clay soils using both portland cement and lime is a well tried and tested technique in many overseas countries, but has not been used to its full potential in Germany, and in particular not in Indonesia. This paper presents mainly the recent experiences on stabilization of local typical poor cohesive soll, obtained from the region Chemnitz, using cement and lime. Based on an extensive experimental research program, it provides a general knowledge and understanding of stabilization of clay soils and in particular the most beneficial type of additives and the quantities to use to achieve the design requirements. The mechanisms involved in stabilization, the differences in the methodologies and the testing criteria for cement and lime stabilization have been identified and their implications on performance evaluation have been discussed. Critical factors affecting stabilization, such as dosage, material processing, curing conditions, etc., have been studied and recommendations have been made to attain a meaningful comparison between cement and lime usage. Also the needs for additional research have also been identified and specific recommendations made.
