Performance Evaluation of Expansive Soil Stabilized with Bagasse Ash and Coir Fibres

Abstract

Soil is the most important foundation substance which supports loads commencing the overlying structure. Soil stabilization is a course of altering various soil resources by different methods in order to create all the preferred engineering properties. Expansive soils have big volume adjust potentials with water content changes causes issues such as foundation damage and failures and it is challenging to facilities. Immense efforts have been spent on finding appropriate methods to stabilize expansive soils, but these stabilizers all had restrictions. Soil stabilization was a major frequent land enhancement method undertook for developing challenging resources of soil. The study reveals a sequences of evaluation carried for assessing an impact of bagasse ash as well coir fibre inclusion to the engineering and shrink-swell activity of extended soils. The soils used for the investigation were collected from local area: Vellode of Erode district. Bagasse Ash were collected from sugar mill, Tittagudi of Cuddalore district. The coir fibres were collected from Perundurai and Gobichettipalayam of Erode district. To explore the influences of bagasse ash and coir fibre on the engineering activity of extended soil, different percentages of bagasse ash of 1% and 2.0% and coir fibre of 0.25% and 0.75% were studied. Unconfined compressive strength test were conducted for determining the compression strengths of the samples with different healing durations. According to this lab evaluation research, this is concluded; the extended soils can be consistent mixture of baggase ashes as well coir fibres.
