Abstract
Monocalcium aluminate and calcium dialuminate were prepared
by heating different mixes of CaO and Al20_~ at 1400° and
1600°C respectively, evidence of which was found by X-ray diffraction
study. Castables were made from the mixes of CA and
CA2 in specific proportions, hydrated by keeping immersed in
water and subsequently tested for strength.
Hydrated cements on firing were found to be converted to
higher aluminates in presence of Al20 3 including CA6• Fusion
behaviours of CA, CA2 and their mixes have been studied. Role
of CA2 in high alumina refractory cements has also been discu~sed.
