Reactions in Portland Cement-Clay Mixtures: Final Report

Report No: 70-R13

Published in 1970

About the report:

This study was an extension of earlier work by Sherwood and Noble to determine the nature of the clay content of common Virginia soils and the strength development of those soils in cement mixtures. In addition, attempts were made (1) to study the relationship between parent materials and their derived soils, (2) to determine any changes in physical and chemical properties down the soil profiles, (3) to study the reactions accompanying cement stabilization of soils, and (4) to determine the soil factors influencing strength development in soil-cement mixtures. The three types of soil chosen for the study were (1) a limestone derived silty clay, (2) a basic intrusive residuum, and (3) a resilient micaceous soil. Samples were subjected to chemical, X-ray, microscopic, and engineering analyses. Results showed that the presence of large amounts of clay in the soil-cement specimens appeared more important than the type of clay in determining short-term strength development.
