Experimental data on free swelling potential of clayey soils

We present experimental data on vertical swelling potential of natural and artificial clayey soils obtained from different regions across the world. The swelling data and the relevant soil properties were acquired from studies that employed standard soil testing techniques and followed recommended procedures to measure vertical one-dimensional swelling potential of the soil samples. In total, the dataset contains 518 soil swelling potential data points covering a wide range of properties/conditions relevant to field applications. The corresponding soil properties are the activity, water content, dry unit weight, liquid limit, plastic limit, plasticity index, and clay content. The dataset presented is of interest of geotechnical engineers and researchers dealing with expansive soils, and provides insights on the influences of various soil’s characteristics on swelling potential natural and artificial clayey soils.
