The method of ground improvement using lime or cement is popular because of the speed, adaptability, and profitability of this method. However, pollution due to alkaline water from lime or hexavalent chromium from cement may occur as a result. To avoid this issue, molasses has been used for the improvement of clay in several studies. However, a satisfactory value indicating ground improvement has not been achieved yet. In this study, surfactant has been added to molasses based soil solidification material previously studied by the authors. The Brazilian test was used to obtain tensile strength value for evaluation of the mechanical properties of the specimens. The tensile strength at seven days of this material obtained through this procedure is compared with that of specimens using distilled water, 10% molasses solution or the specimens used in the authors’ former study. Four types of curing condition combined with air drying and moist curing were adopted. The highest average value of the tensile strength appeared during 7-day air curing and was 1.3 times that in the authors’ former study.
