Abstract: Building derived materials (BDM) are waste materials that are generated during constructions and demolition of structural components of buildings. Management and proper disposal of these wastes has assumed prime concern for modern civil engineers. The present study is aimed at characterization of BDM to ensure their recycling and reuse in practical purposes. One possible mode of reusing BDM is ground improvement. At present, BDM are used in the
form of recycled coarse aggregates, after subjecting the former through various physical and chemical refinements, which incur extra cost. To address this issue, the present study emphasizes on the use of virgin BDM, which conserves natural aggregate, reduces the impact on landfills, saves energy, and thus can provide cost benefit. Hence, in this study, BDM are characterized to assess their compatibility when used in conjunction with local soil. It depends upon the type of soil and the contaminants present in the soil. The BDM in this study are characterized through physical investigations, microscopy, and exposure to chemically aggressive environment like acids, salts, and seawater to study their response. The results thus obtained show that BDM are highly susceptible to aggressive environment and appropriate measures must be adopted while using BDM in chemically aggressive environment.
