摘要: Abstract Research on quantification of the size and porosity interface between reinforcing steel concrete is limited in current published literature. This paper presents a reliable accurate method for steel-concrete using technique Backscattered Electron (BSE) imaging. Details sample preparation procedure designed to minimize damage due grinding polishing are presented. A new thresholding separate porous band at from cement pastes proposed. It found that there relatively wide with large pores voids near interface. also around bar not uniform, water ratio can significantly affect distribution Quantification as proposed this importance crack prediction corrosion-affected reinforced structures.
