ABSTRACT:
A refractory cement with outstanding mechanical properties contains 10 to 30 parts by weight of C.sub.4 A.sub.3 S clinker and 70 to 90 parts by weight of an aluminous clinker including 30 to 75% CA. This cement may be prepared by either grinding said clinkers to a specified fineness and then mixing the same, or by grinding said clinkers simultaneously and jointly to said specified fineness. The novel double clinker cement allows concrete with considerably improved refractory and mechanical properties to be prepared, as compared to the corresponding products known up to now.
