A Study on Durability of High Performance Concrete with Industrial Wastes

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, innovation of supplementary materials and composites has been developed. In other side, India has an enormous growth in the steel and copper industries yielding many by-products. If the by-products, such as copper slag and Ground Granulated Blast Furnace Slag (GGBS) are not disposed of properly, they may cause environmental hazards to the surrounding area. Considering the long-term performance and stability of structures, 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 (HPC). The paper presents an experimental investigation to assess the durability parameters of HPC with the industrial wastes. Durability parameters such as water absorption and chloride penetration were studied.
