Abstract:
In Indiana, large quantities of recyclable materials - such as steel slag, blast furnace slag and fly ash - are generated each year as by-products of various industries. Instead of disposing these by-products into landfills, we can recycle them into beneficial civil engineering applications by replacing traditional construction materials with these industrial by-products. Replacing traditional materials with these industrial by-products may be a cost-effective alternative that can help save natural resources and reduce the costs associated with landfilling. In this research study, the suitability of using mixtures of steel slag and Class-C fly ash and mixtures of steel and blast furnace slags to replace lime in subgrade stabilization applications was evaluated. Initially, mixtures of steel slag and Class-C fly ash were explored as a replacement for lime. In situ soil collected from a proposed implementation project was mixed with 10% (by weight of soil) of steel slag and Class-C fly ash mixtures. The following mixtures of steel slag and Class-C fly ash were considered in this study: 5% steel slag-5% Class-C fly ash, 7% steel slag-3% Class-C fly ash and 8% steel slag-2% Class-C fly ash by weight of soil. Since the Class-C fly ash used in this study is expensive, a 7% steel slag-3% blast furnace slag mixture by weigh of soil was also investigated for use as an alternative mixture that could also be used for soil stabilization.
