Silica Fume in Refractory Description
Silica fume in refractory enhancing the fluid of pouring
refractory, reducing the volume of used water, beeasy to shape, and
raising the production efficiency. Because of its
untramicrostructure for gap filling, the compact and intensity of
refractory gain rising by a wade margin. Silica fume in refractory
is a highly effective pozzolanic material, so it's easy to come
into being Mullite Phase, under the premise that Al2O3 exists,
enhance elevated temperature strength and thermal shock of
refractory.
Silica Fume has been used as an addition to concrete up to *5
percent by weight of cement, although the normal proportion is 7 to
*0 percent. With an addition of *5 percent, the potential exists
for very strong, brittle concrete. It increases the water demand in
a concrete mix; however, dosage rates of less than 5 percent will
not typically require a water reducer. High replacement rates will
require the use of a high range water reducer.
