Hydration stages: 1st Ind. – 1st induction; 1st Alu. – 1st aluminate (C3A and C4AF) reaction; 2nd Ind. – 2nd induction; C3S and 2nd Alu. – reaction of C3S and 2nd aluminate restart. Anh. – anhydrite. (d) is the reaction products of aluminate phase represented by (a) and (b); (e) is the reaction product of C3S from (c).
