- The manufacturing
process of Castle High Alumina Cement clinker resembles that of a
metallurgical foundry and the cement is based on calcium aluminates
rather than the calcium silicate basis of Castle Ordinary Portland
- High alumina cement is
obtained by fusing or sintering a mixture, in suitable proportions,
of alumina and calcareous materials and grinding the resultant
product to a fine powder.
- The raw materials used
for the manufacture of high alumina cement are limestone and
- High alumina cement,
sometimes called calcium aluminate cement or aluminous cement, is
very different in its composition and in some properties from
portland cement, but concreting techniques are similar.
- The converted form of
HAC may show a reduction in strength and become more susceptible to
certain forms of chemical attack.
- It is known that the
initial product of hydration of high-alumina cement at low
temperatures, often labeled “CAH10,” contains both crystalline and
- Hydration and strength
del'elopment characteristics. of high alumina cemellt (HAC)
containing sodium sulfate and a variety ofdifferent zeolites types
containing clinoptilolite, chabazite, sti/bite, and natrolite.
- Applications of HAC
include sulp hate-resis tant cements, bore hole plugging cements , f
as t-se t ting patching compounds, rock anchors, grouting, cold
temperature concreting, and refractories . Recently, HAC has been
used instead of CaC12 as an accelerator.
- Reaction mechanisms of
stratlingite formation in highalumina cement (HAC)-zeolite systems
were studied. A component separation method that made it possible to
study individual reactions involving hydrated HAC and zeolite.
- The application of
high-alumina cement in structural members has been banned since the
early 1970s in virtually every country in the world. The results of
this study suggest that the use of conversion-inhibited high-alumina
cement in reinforced concrete structural members, especially in
aggressive environments, is a potential solution to these
- Effect of binder and
its amount on the high alumina self flow castable has been studied
using X-ray Powder Diffraction (XRD) technique, which showed mullite
phase in sol containing castable and grossite in cement containing
- Aluminate cements are
applied mainly in fire-resistant concretes.
