Abstract
ABSTRACTThis research article reports the comprehensive experimental studies conducted on the identification of corrosion mechanism. The study is made in two different types of samples taken from reinforced concrete containing class–F Fly ash and steel bar with different fine aggregates such as river sand and manufactured sand. It also reports the study under different curing conditions to find out corrosion attack on fly ash concrete structure. Cement placed by means of Fly ash, concrete mixes prepared with 20%, 30%, 40% weight of cement and using16mm diameter steel bar 100mm length with 25 mm clear cover were used as samples. Corrosion process was investigated in embedded steel bar by using Tafel polarization and AC Impedance methods by using ACM Instruments (UK).This study will help in identifying the level of corrosion between the usage of river sand and the manufactured sand.
