Strengthening of Soil by adding Lime and Glass Fiber as Stabilizing Materials for the Construction of High Rise Buildings

Abstract

The main aim of this research is to increase the strength properties of the weak soil by using stabilizing materials for the construction of high raised buildings on weak soils. As we all know that the most important thing in construction industry is soil. In this research we are adding stabilizing materials like lime and glass fibers to the weak soil to increase the strength parameters of the soil. The addition of stabilizing materials and admixtures to the soil leads to the increase in the strength parameters of the soil. There are various Infrastructural projects which are constructed on the soil, in many of these cases the black cotton soil is not suitable, because the Black cotton soil is weak in strength and which has low engineering properties. Black cotton soil has more swelling property and high shrinkage nature. To overcome these problems and to improve the engineering properties of the black cotton soil, we are adding Lime and Glass fibers as the stabilizing materials in the weak black cotton soil. The engineering properties like strength, compressibility and bearing capacity of the soil were increased by stabilizing the weak soil these stabilizing materials. This work mainly concentrates on the feasibility of the usage of lime and glass fibers as the stabilizing materials for the black cotton soil. The percentage of Lime and glass Fibers used in black cotton soil varies in different proportions like 2%, 4%, 6%, 8% and 10%. All the necessary tests were conducted to get the results. The properties like Liquid limit, Plastic limit, Compaction characteristics values and Differential free swell index of soil have been studied in this research.
