Strength improvement of clay using waste soda lime glass powder and sodium alginate

Abstract

Clayey soil is generally weak in nature. When constructions are carried out on clayey soil, especially highways, railways, buildings and embankment face many difficulties. Therefore, the improvement of such type of soil is crucial. Soil stabilization can be done by different methods, which includes stabilization using lime, cement and waste materials from various industries etc. Soda lime glass powder is a waste material from glass industries. Clay is a type of soil that can be categorized as problematic due to its weak properties like volumetric expansion, low strength etc. In this soil, the shear strength of the soil is less due to its very high initial moisture content and plasticity. Construction is difficult in such type of weak clay. The main aim is to identify the properties of clay. And, to study the effect of waste soda lime glass powder (WSLGP) and sodium alginate (SA) on clay. Standard proctor compaction test and Unconfined strength test is carried out using varying (3%, 6%, 9%, 12%, 15%) percentages of WSLGP and optimum WSLGP content is determined. The sodium alginate in varying (0.25%, 0.5%, 0.75%, 1%, 1.25%) percentages is added to clay with optimum soda lime glass powder. Standard proctor compaction test and Unconfined compressive strength test were carried out. The maximum strength is obtained at optimum 12% WSLGP and 1% SA content.
