ground granulated blast furnace slag cement factor
Ground Granulated Blast Furnace Slag an overview
The use of the GGBFS in the slag cement is starting from 36% in Turkey. Generally, the concretes produced with 70% or more GGBFS cements provide adequate strength to mechanical impacts. Lane and Özyıldırım (1999b) investigated constant water to cement Grade 120 GGBFS-PC binary mixes with 25%, 35%, 50%, and 60% replacement.
