Description: This 36-page state-of-the-art report provides guidance on the use of cement kiln dust (CKD) to stabilize clay soils, with and without being combined with portland cement, fly ash, or lime. Data on the type and level of CKD additions and the affects on the engineering properties of soil are presented. This report is also found on DVD021.
The report contains up-to-date information that has been available on the use of cement kiln dust (CKD), both exclusively, and in combination with other stabilizing material such as: lime, portland cement, and fly ash. The data on the type and level of CKD additions and the resulting engineering properties of the clay-soils such as unconfined compressive strengths, Proctor moisture-density relationships, California bearing rations (CBR), liquid- and plastic-limits, swelling, shrinkage, and permeability characteristics have been documented. The informational gaps have been identified and needed additional work has been recommended. This compilation is intended as a guideline to the use of CKD in soil and clay stabilization for application in the road structural layers (e.g., the subbases).
