Compaction and shear strength characteristics of colemanite ore waste modified active belite cement stabilized high plasticity soils

► Reducing energy consumption in cement production is of global concern. ► Active belite cement production seems to be more environmental friendly that of OPC. ► BC inclusion results in a more brittle failure compared to OPC inclusion. ► BC can effectively improve the engineering properties of clay soils. ► The variation of friction angle with cement dosage and curing periods scatters.
