Abstract
1.0 Introduction
For construction projects, the most important factors in any project are its cost, performance, safety, durability and time. Building any type of structure on a black cotton clay surface can be problematic due to the high spreading potential and/or low strength properties of the soil. Soil stabilization is the improvement of soil strength or bearing capacity by compaction, dosing or the addition of suitable additives or stabilizers. Many soil stabilization techniques have been proposed to prevent uneven soil settlement and degradation. Stabilization of black cotton soil using fly ash, lime, rice husks and bio enzyme, an organic, non-toxic liquid enzyme, is a common practice worldwide. called Terrazyme for improving the strength of expansive black cotton clay The present work provides a bio enzyme- and Fly Ash-based approach to soil remediation.
Wide spread of black cotton soil in Bilaspur region has created challenges and problems in construction activities. Therefore, the task was undertaken to study and improve the technical properties of the black cotton soil of Bilaspur district. The process of improving soil and resilience is called soil stabilization. The main objective of stabilization is cost reduction and efficient use of locally available material. Soil stabilization with Class F fly ash offers many advantages, such as improving technical properties, cost-effectiveness and environmental friendliness. Sipat Super Thermal Power Station (NTPC) Sipat Dist. Bilaspur Chhattisgarh which is about 10 km. Bilaspur city generates huge amount of fly ash. Terrazyme is a natural, non-toxic, non-corrosive liquid enzyme preparation, and this Terrazyme, made from plant extracts, improves technical properties and increases soil stability. In this work, different parameters of F-fly ash and Terrazyme were studied on local soil.
The aim of this research is to improve the technical properties of black cotton soil by adding different percentages of fly ash to it. (5%, 10%, 15%) by ground weight at different doses viz. 1.0 m3 / 200 ml, 1.5 m3 per 200 ml and 2.0 m3 per 200 ml Terrazyme organic non-toxic liquid enzyme and make it suitable for construction.
1.1 Objectives 1. Determination of geotechnical properties of black cotton soil. 2. Evaluate the effect of Terrazyme on basic soil properties. 3. Evaluate the effects of Terrazyme and F-Fly Ash on basic soil properties. 4. To determine the effect of addition of enzyme and F-fly ash to black cotton soil on its properties such as consistency limits, standard proctor test, free swelling index, California bearing ratio test and unconfined compressive strength of the soil.
A series of standard Proctor tests (for calculating MDD and OMC), UCS and California Bearing Capacity (C.B.R) tests are performed on both raw black cotton soil and soil mixed with Terrazyme and fly ash. We compare the properties of raw black cotton soil, black cotton soil mixed with fly ash and Terrazyme. It was observed that the properties of black cotton soil were properly improved by mixing.
