STABILISATION OF CLAYEY SOIL USING GRAPHENE OXIDE AND FLY ASH by Avtar Singh
Abstract
Soil plays an important role in civil engineering. Properties of soil vary according to type of soil. If soil is unfit for the purpose of construction, structures constructed on itshow earlier trouble and ultimately collapse. Construction on clayey soil is difficult as this type of soil shrink & swell with differing water percentage.Generally, clayey soil has low strength and in addition to it high dampness weakness. Terrible soil subgrade can make different issues for the asphalt and structures, in this manner an appropriate adjustment system is needed. In modern world, different types of chemicals are used for stabilisation process. After studying properties of Graphene Oxide (G.O), it was concluded that G.O exhibits a proper nature for stabilization process. Main aim of this research is to evaluate performance of graphene oxide in stabilizing the soil to an optimum level. In this research, Fly Ash is also used along with G.O. According to ISCS, soil used is categorised as clayey soil with intermediate compressibility (CI). Various concentrations of G.O (0.25%, 0.5%, 0.75% & 1.0%) along with different proportions of fly ash (15%, 20% & 25%) were added to the soil to check compaction characteristics, California Bearing Ratio & Unconfined Compression strength. Results showed that with an increase in G.O concentration CBR and UCS values of soil also increases.
