Etringite (Ca 6 Al 2 (SO 4) 3 (OH) 12 25 (H 2 O)) and Calcium Silicate Hydrate (2CaO.SiO 2 .4H 2 O) were identified as the binding phases in the real size brick samples after 2 days of pre-curing and 28 days curing at 50° C and 95% relative moisture. The water absorption rate was found to be 27.7 % in terms of mass.
