lime and flyash

Inefficient soil characteristics are a major problem in engineering projects today. Sometimes the first stage in the building is to change the characteristics of inappropriate soil. Early signs of degradation in pavement structures on low soil subgrades include pavement that fails too soon. The potential for clayey soil to exhibit unfavorable engineering features, such as low bearing capacity, high shrinkage, swell characteristics, and high moisture susceptibility, is typically present. It is common practice to stabilize these soils to increase their strength. In order to enhance the engineering performance of soil, a technique called soil stabilization is used to add a binder to the soil. This study details how the addition of both lime and fly ash increased the cohesive soil's strength in the surrounding area. Fly ash has been used to bind non-cohesive soil, granular soil, or soil that is poorly cohesive in place of the typical usage of lime alone in soil that contains clay and is highly cohesive. Fly ash is mostly utilized to support the base course or sub-base.
