✦ Synopsis

The effects of adding ground limestone to high alumina cement mortar were studied. The hydration was c~ed out at 60°0 to form the cubic hydrate C AM directly, hence avoiding the conversion of CAM to o I O3AM6, an~ a~ 20 C, Other experiments involved subsequent carbonation with CO 2 an~ thermal ~reatment. The formation of stable carbonated phases was evident even at very early ages.

The use of temperatures higher than 30°0 during the hydration of 1:3 high alumina cement mortar leads to the formation of the cubic hydra te C3AH~, hence avoiding the conversion of CAHIo to C3AH 6. The subsequent-carbonation of 03AH 6 with 002 and therm~l treatm@nt leads to the formation of stable c
