Hydration and properties of sodium sulfate activated slag

PROPERTIES OF ALKALI-ACTIVATED FLY ASH CONCRETE BLENDED WITH SLAG

Slag Hydration in composite cements

Despite reported synergies between alumina rich supplementary cementitious materials (SCMs) and limestone, previous studies have focused on up to 5% limestone content. Slag hydration in the presence of 10% limestone is reported in this paper. Hydration was followed through chemical shrinkage, calorimetry, thermal analysis, electron microscopy and X-ray powder diffraction. The results show that ...

influence of sodium oxide on properties of fresh and hardened paste of alkali-activated blast-furnace slag

:the aim of this work is to investigate the influence of sodium oxide on properties of fresh and hardened paste of alkali-activated blast furnace slag from isfahan steel plant. the silica modulus (sio2/na2o) of activator was adjusted at 0.6 and a number of mixes were designed in such a way to contain different levels of sodium oxide including 1, 2, 3, 4, 5, and 6% by weight of dry slag. the mos...

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

Effect of Na3PO4 on the Hydration Process of Alkali-Activated Blast Furnace Slag

In recent years, the utilization of different non-traditional cements and composites has been increasing. Alkali-activated cementitious materials, especially those based on the alkali activation of blast furnace slag, have considerable potential for utilization in the building industry. However, alkali-slag cements exhibit very rapid setting times, which are too short in some circumstances, and...
