Properties of hot-pressed calcium aluminate cements
· Simultaneous heating and pressing techniques were applied to ordinary calcium aluminate cements (40 Al 2 O 3) and high aluminate (72 ) cement.The compressive strength of the former when hot pressed at 50 000 psi 250°C 1 2 hr. is 51 000 psi while the latter is 45 000 psi. The strengths of comparable standard pastes after 24 hours curing are 6 000 and 4 300 psi respectively.

A refractory cement is made by combining a clinker which is substantially all CaO.Al 2 O 3 (CA) with a roughly equal weight amount of an alumina which has been calcined to produce a carefully controlled morphology particularly specific surface and pore size within relatively narrow ranges. Both materials are very finely divided at least 80 passing a 325 mesh screen.
