ABSTRACT
Soil
stabilization can be explained as the alteration of the soil properties by
chemical or physical means in order to enhance the engineering quality of the
soil . The main objectives of the soil stabilization is to increase the bearing
capacity of the soil ,its resistance to weathering process and soil
permeability. The long-term performance of any construction project depends on the
soundness of the underlying soils. Unstable soils can create significant
problems for pavements or structures, Therefore soil stabilization techniques
are necessary to ensure the good stability of soil so that it can successfully sustain
the load of the superstructure especially in case of soil which are highly
active, also it saves a lot of time and millions of money when compared to the
method of cutting out and replacing the unstable soil. This paper deals with
the complete details about the stabilization using solid waste materials. Some
waste materials such Fly Ash, rice husk ash, pond ash, waste fiber materials
may use to make the soil to be stable.
Addition of such materials will
increase the CBR value, shear strength, liquidity index, plasticity index,
unconfined compressive strength and bearing capacity etc. Disposal of these waste materials is essential
as these are causing hazardous effects on the environment. With the same
intention literature review is undertaken on utilization of solid waste
materials for the stabilization of soils and their performance is discussed.
