Alite cannibalistic

Photograph 7-49 Large, joined crystals of blue alite (cannibalistic) and round, brown-tan belite with unusually wide lamellae. Well-differentiated matrix. (S A6669)... 

The desirable characteristics of Class H well cement were listed by Arbelaez (1990) free lime levels less than 0.5% with a uniform distribution, CjA less than 6.5%, no weathered clinker, using only the 12.7-to 38.1-mm clinker fraction for the cement, relatively hot burning without production of cannibalistic alite, and avoidance of ragged belite by rapid cooling. 

Cannibalistic (fused) alite Erratic thickening times and unpredictable retarder response (Reeves, Bailey, and McNabb, 1984) reduced activity level (Dorn, 1985)...
