NICMAR Journal of construction managementSummary: Long-term performance of structures has become vital to the economies of all nations. Concrete has been the major instrument for providing stable and reliable Infrastructure. Deterioration, long term poor performance, and inadequate resistance to hostile environment, coupled with greater demands for more sophisticated architectural form, led to the accelerated research into the microstructure of cements and concretes and more elaborate codes and standards. As a result, innovative supplementary materials and composites have been developed. On the other side, India had an enormous growth in the steel and copper industries. The following are major by products from these industries: (i) Copper Slag - A by product of copper refinery (ii) Ground Granulated Blast Furnace Slag (GGBS) - A by product of the manufacture of iron in steel industry. If they are not disposed off properly, they may cause environmental hazards to the surrounding area. Considering the long term performance and stability of structures, in this study, it is planned to replace some percentage of fine aggregate with copper slag and some percentage of cement with GGBS to develop High Performance Concrete. This paper presents an experimental investigation to assess the durability parameters of High Performance Concrete with the industrial wastes. Durability parameters such as water absorption and chloride penetration are to be studied.
