soil stabalization using rice husk ash and lime sludge pdf
Abstract
The feasibility of using two industrial wastes, rice husk ash (RHA) from a rice mill and lime sludge from a paper factory, for soil stabilisation in road construction activities, was studied. Both waste materials are produced in India as industrial by-products. The effects of adding RHA and/or lime sludge on Proctor's density, Atterberg's limits, soil plasticity and the unconfined compressive strength of a soil were studied. RHA and lime sludge addition increased the liquid limit and plastic limit of a soil and decreased the dry density. The unconfined compressive strength had a maximum value for a soil mix containing 10% RHA and 16% lime sludge. The results suggested that RHA and lime soil could be successfully used for the stabilisation of a clay soil.
INTRODUCTION:
Clays exhibit generally undesirable engineering properties. They tend to have low shear strengths and to lose shear strength further upon wetting or other physical disturbances1 . They can be plastic and compressible and they expand when wetted and shrink when dried. Some types expand and shrink greatly upon wetting and drying – a very undesirable feature. Cohesive soils can creep over time under constant load, especially when the shear stress is approaching its shear strength, making them prone to sliding. They develop large lateral pressures. They tend to have low resilient modulus values2 . For these reasons, clays are generally poor materials for foundations3 . The annual cost of damage done to non-military engineering
structures constructed on expansive soils is estimated at $220 million in the United Kingdom and many billions of dollars worldwide4
