Development of Strength for Calcium Aluminate Cement
In the present study the development of strength in different calcium aluminate cement (CAC) mixture mortars with granulated ground blast-furnace slag (GGBS) was investigated. The substitution of GGBS levels was 0 20 40 and 60 weight of binder of which the CAC used in this study naturally contained C 2 AS clinker as a secondary phase.
