Stabilization of Black Cotton Soil using Lime and G.G.B.S (Ground Granulated Blast Furnace Slag) As A Admixtures

Abstract

Soil Stabilization is one of the modern techniques for modification of soil which are using in our daily life in construction. Due to increase in population land is also getting scarce so we need to build in the available area. So this technique we use is called Soil stabilization or modification of soil. As we know that some of the soils are not useful for construction. As a result while constructing pavements like national highways (NH) we should definitely build the pavement on soils like black cotton soil by improving its strength because the original nature of the soil will have poor bearing capacity and less strength. So by adding admixtures from Industrial wastes such as Ground granulated blast furnace slag(GGBS) which is the waste of iron ore i.e., in powder form and Lime which will increase the bearing strength of the soil, So that it will also increase the pavement design over long period of time which is the ultimate goal for the design of the pavement or any other construction purpose. So by adding these admixture using the industrial waste which is available in a low cost so that we can easily improve the strength of the soil because of the availability of admixtures in economy. After adding the admixtures Soil should be tested by some basic tests of U.C.C (Unconfined Compressive Strength) and also California bearing test (CBR) and also some basic tests like MDD (Maximum Dry Density) & OMC (Optimum Moisture Content), Plasticity index and liquid limit etc.., should be carried out in order to test the improved strength of the soil.
