Evaluation of Shear Strength of Collapsible Soils by Toner Stabilization Method

Abstract

The research is oriented to investigate the improvement in the shear strength of soil after the addition of the toner which is usually used in printing machines. Soil is the most important component in the construction industry as every structure has to be built on the soil. The most widely explored aspect in the construction industry is how the soil should be stabilized. Various techniques are being applied all over the world in the soil during construction which enhances the soil stabilizing. The soil stabilization includes different materials such as cement waste, lime, lime and cement mixture, and high-density polyethylene particles. Toner is a relatively new material to be used as an additive for soil stabilization. The presence of pigment and iron-oxides present in toner helps in increasing the strength of the soil. In this study, toner was added in different percentages of the total quantity, and various tests of soil to determine the strength of soil were performed like Sieve analysis, Atterberg limits, California bearing ratio, and Modified proctor tests. The results obtained from performed tests suggest the toner is a promising admixture for soil stabilization.
