Blast furnace slag cement:a ~(29)Si and~(27)Al NMR study

摘要

Ground granulated blast-furnace slag(GGBS)is a secondary product of cast-iron industry that can be used like a standard hydraulic binder.Nevertheless,it requires a chemical activation to start the slag-hydration process.In this work,four activators are studied.Solid-state NMR and mechanical compression tests are used to determine the hydration products microstructure and performances.To cite this article :S.Murgier et al.,C.R.Chimie 7(2004).
