The porous and complex microstructure of reinforced concrete is responsible for its deterioration from external agents attacking its surface. Corrosion of reinforcement bars in concrete deteriorates concrete over a period of time and thus affects its durability. Corrosion of reinforcement bars is affected by quality of concrete, proper design and construction, and environmental conditions. Chloride-induced corrosion of reinforcement is a common phenomenon for concretes subjected to marine environment or de-icing salts. The resistance of concrete to chloride-induced corrosion depends mainly on chloride permeability and compounds present in the microstructure of concrete. In this paper, an effort has been made to study the microstructure of high-strength (M100) self-compacting concrete (HSSCC) with and without adding hybrid steel fibers subjected to accelerated corrosion. Chloride permeability and microstructure of HSSCC with and without fibers is also studied. Though several test methods are there to measure durability of concrete subjected to various chemical attacks, the actual behavior of concrete and its compounds can be found only by studying its microstructure, which will be useful to develop better concretes. X-ray diffraction (XRD) analysis has been carried out to determine the phase amounts of various compounds in multiple phase mixture of HSSCC with and without hybrid steel fibers. Scanning electron microscope (SEM) is used to visualize the elements in the microstructure of the HSSCC concrete.
