Abstract

Abstract: This study focuses on the acid resistance of fine bone china ceramic aggregate (FBCA) concrete. Natural sand was partially and fully replaced by FBCA. The concrete specimens were exposed to 3% sulphuric acid solution up to 180 days. The main parameters identified were change in mass, compressive strength and microstructural changes. The changes in microstructure were examined by Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. The stable form of raw FBCA and denser calcium silicate hydrate gel in FBCA concrete provide a superior resistance to acid attack than traditional concrete.
