This study investigates the impact of degree of mixing of stabilisation materials and soil under physical mixing on the efficiency of stabilisation remediation. Experiments were designed in terms of the type of stabilisation material, dosage of agent and the number of physical mixing times. Monocalcium phosphate (abbr. MCP), which represents chemical precipitation, and Zeolite, which is physically adsorbed, were used to stabilise and remediate industrial Cd-contaminated soils, and A measurement method for the degree of mixing based on the bivariate coefficient of variation (BCV) was constructed to analyse the influence of mixing uniformity on stabilisation efficiency. The results indicated that (1) comparing the rate of change of BCV (coefficient b), zeolite (0.19–0.31) was larger than MCP (0.07–0.14). (2) At the same dosage, the amount of mixing required to achieve 100% mixing uniformity between MCP and contaminated soil was lower than that required with zeolite. (3) Incubation treatment could increase the stabilisation efficiency of MCP by over five times, but could not significantly improve the stabilisation efficiency of zeolite. After a comprehensive consideration of the restoration cost, the suitable number of times the two types of stabilisation materials should be mixed was determined to be limited to two times. This experiment is not enough for the study of the specific principle of action, the next step should be from the stabilisation materials and mechanisms, soil properties, and further discuss the effect of the mixing uniformity of materials and soil on the stabilisation of the restoration.
