The structures of the slags
were also detected by FT-IR spectroscopy (Nicolet 5DXC).
ions are electrically driven into the pore network, leading to an increased charge transfer during the test, so the fact that Figure 6(b) shows a lower charge passed value for alkali-activated slags
than the Portland cement reference can be taken to indicate that the actual chloride movement through the materials is likely to be much slower.
Ground BFS is used as an admixture in concrete or as an additive in the manufacture process of Portland slag
cements in countries where large amounts of BFS is available.
, since in this way it would be possible to decrease the incubation times and consequently to increase the thickness of the crystalline layer.
The application of steel slag
from steel mills was not very popular until the late 1990s, for there were vast amounts of blast-furnace steel slag
available, while the steel slag
from steel mills was used for the manufacture of chemical fertilizers, where only the so-called Thomas steel slag
, a by-product of steel production from phosphorous raw iron, was used.
The free oxygen ion may form in metallurgical slags
which are an integral part of the gas-slag
-metal ternary system, as a result of the exchange reactions or in the slag
, between the slag
components with the metal and gas that are in contact with these component.
that contain calcium aluminates can be considered as a possible source of raw material for the production of fast-setting and very strong cements .
For regulation of data from measured results of quantity in percentage of slag
components, it's done statistical model.
The use of steel industry slags
as a substitute for traditional limestone has a substantial history in Ohio (Williams 1946; Volk and others 1952; Jones 1968).
greatest sin (putting aside the obvious) is that it just isn't funny.
Barren tail slags
were discharged directly into the Columbia River until two years ago when environmental considerations made this an unacceptable practice.
