Dimensional Control in Tec-Cement Concretes over Time
{"Image DocumentName": "Dimensional Control in Tec-Cement Concretes over Time", "Image ImageDescription": "By adding MgO volume changes are minimised to close to neutral. So far we have observed significantly less shrinkage in TecEco tec - cement concretes with about (8-10% substitution OPC) with or without fly ash. At some ratio, thought to be around % reactive magnesia and 90 \u2013 95% OPC volume changes cancel each other out. The water lost by concrete as it shrinks is used by the reactive magnesia as it hydrates eliminating shrinkage. Note that brucite is > mass% water and it makes sense to make binders out of water! More research is required to accurately establish volume relationships.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
