- Abstract
This article focuses on cement hydration by soft x-ray transmission microscopy. Portland cement is produced from a finely-ground mixture of limestone and clay or shale that is fired at about 1400 degree celcius to produce a hard clinker that, after cooling, is re-ground with a small amount of gypsum to give a fine gray powder. The resulting cement reacts with water to produce calcium hydroxide, calcium aluminate hydrates, and, perhaps most importantly, calcium silicate hydrate. Calcium silicate hydrate is the primary hydration product that gives concrete most of its characteristic mechanical properties.
