The Drying Cake (DC) System is a simple-to-use laboratory device for measuring the Suction Stress Characteristic Curve (SSCC), which defines changes in effective stress for varying saturation conditions. From the SSCC curve, the user can obtain the Soil-Water Retention Curve (SWRC). The SSCC may be measured along either wetting or drying paths in as little as 5-7 days. The system is applicable for all major soil types, including sand, silts, and clays.
