HIGH ALUMINA CEMENT
Description for High Alumina Cement
High Alumina Cement uses bauxite and lime as the raw materials,
which is a kind of hydraulic binders with aluminate as the main
mineral composition that through calcining and grinding fine
according to certain proportion. Its professional title is
Rongsheng as one of professional high alumina cement suppliers
manufactures all kind of refractory cement for various furnaces and
kilns building to resist sulfate attack.
Properties of High Alumina Cement
Early strength characteristics: Its early strength increase rate is
far more than rapid hardening portland cement, high alumina cement
is suitable for emergency repair engineering. Take restrictions on
the use in structure engineering to prevent from the long-term
Larger heat of hydration: Early cement hardening heat release is
larger. Compared with Portland cement at same grade, just a day can
release 70 ~ 80% of the total heat of hydration. Due to the several
kinds of heat release, high alumina refractory cement is suitable
for low temperature curing of concrete engineering.
Strong resistance to sulfate attack: hydration process generates
aluminium hydroxide gel to form a protective film instead of
non-precipitating free alternating current calcium hydroxide.
Latterly in the crystal transformation in the process of the
erosion resistance will decrease.
Good high temperature resistance: High alumina refractory cement
can be used as heat resistant concrete cementitious materials to be
configured to heat resistant concrete.
Application of High Alumina Cement
High alumina cement is mainly used to configure refractory castable such as high alumina low cement castable which can build or repair
furnace or kiln for heat insulation or high temperature erosion.
Calcium aluminate cement has high temperature resistance
performance,can keep high strength under higher temperature,and the
high temperature property will be improved along with increase of
the CA2 content .As bonding agent,with different aggregate,we can
make refractory castables with 1400°c refractoriness.
