Glass structure of industrial ground granulated blast furnace slags (GGBS) investigated by time-resolved Raman and NMR spectroscopies

چکیده
Ground granulated blast furnace slags (GGBS) are glassy by-products from iron production that commonly used as supplementary cementitious materials in blended cements. The glass structure of seven industrial GGBS was investigated by Raman and nuclear magnetic resonance spectroscopies. complex composition the induced multiple analytical challenges. Under usual continuous excitation, signal masked strong luminescence, so analysis carried out on a time-resolved (TRR) device. TRR allowed to eliminate luminescence resulted exploitable spectra showed variations line with theoretical NBO/T values. 27Al 29Si NMR complicated presence paramagnetic nuclei wide variety environments. Nevertheless, Al present network former, mainly fourfold coordination careful analyses comparison polymerization based their composition.

In the current work, the properties of cement pastes doped with high amounts of ground granulated blast-furnace slag (HVS) were investigated. Portland cement (PC) was substituted with ground granulated blast-furnace slag (donated as slag) at very high amounts of 85%, 90%, 95% and 100%, by weight. PC paste without any content of slag was used as a reference. Some fresh and hardened properties su...
