Calcium carboaluminate

In cements with a sufficiently high tricalcium aluminate content the calcium carbonate of limestone may react with tlus phase, yielding calcium carboaluminate hydrate (C A CHjj). Up to about 6 wt% of calcium carbonate may be consumed in this reaction within 28 days (Ingram and Daugherty, 1992). Whether the formation of calcium carboaluminate also contributes to a strength increase of the hardened cement paste remains uncertain. [Pg.30]

An aggregate particirlarly suitable for use in combination with calcium aluminate cement is limestone. The calcium carboaluminate hydrate (C aCHjj) formed in the reaction of the CaCOj of the limestone with the calcimn aluminates of the cement contributes to an improved bond between the hardened cement paste and the aggregate sitrface. [Pg.184]
