| description | The influence of aggregate geochemical properties on the development of the microstructure and bond strength at the interfacial transition zone (ITZ) between aggregate and the hydrating cement paste was studied. The mineral phases and microstructure at the ITZs of three commonly used concrete aggregates (quartzite, basalt, and limestone) with contrasting chemical properties were analysed using scanning electron microscopy with an energy dispersive X-ray analyser and X-ray diffraction. It was observed that differences in microstructure and mineral phases exist at ITZ between the three different aggregates studied. The limestone in particular produced a porous ITZ as a result of chemical interaction. |
