Abstract

Concrete is always affected by various physical and chemical attacks under environmental conditions. Acid attack is one of the common phenomenon, which affects the microstructure of concrete, and thus decreasing the strength and durability. Several researchers have reported the effects of acid attack on modern day concrete through strength and durability studies, but concrete has a complex microstructure, so it is very difficult to constitute the realistic models of its microstructure from which the behaviour of the material can be reliably predicted. In the present study, High Strength Hybrid Fiber Self Compacting Concrete (HSHFSCC) cubes of M100 grade are prepared using quartz materials. The specimens are cured for 28 days in water and then immersed in HCl and H 2SO4 solutions with 5% and 10% concentration for 28 days and 90 days. X-ray diffraction (XRD) analysis is carried out to determine the phase amounts of various compounds in a multiple phase mixture of HSHFSC concrete. Scanning Electron Microscope (SEM) is used to visualize the elements in the microstructure of the HSHFSC concrete.
