Binder using ground granulated blast-furnace slag with specific surface area 20000cm2/g (GGBS20000) for ultra-high strength concrete were examined. As a result, it was possible to improve flowability of mortar by use proposal binder GGBS20000. And GGBS20000 also had the effect on improvement early-age mortar. However, which used silica fume more effective than produce high long-term strength.
An experimental study of interactions between hydration and early drying was carried out on a mortar with GGBFS volume as high the OPC volume. 1 day after casting, subjected to 6-month unidirectional in natural surrounding conditions laboratory. At end exposure period, Portlandite content, water porosity pore size distribution were found be not uniform along material. When approaching exposed s...
Using ground granulated blast-furnace slag (GGBS) under different alkaline conditions, we studied the mechanisms and extents of Cr(VI) reduction and sorption and compared them to reactions with Portland cement (PC). We also investigated the effects of mixing PC/GGBS ratios on Cr(VI) dissolution after carbonating the substrates. We observed a complete sorption and reduction of Cr(VI) to Cr(III) ...
