The Ohio project led to the conclusion that "The use of
GGBF [Ground Granulated Blast Furnace] slag in concrete pavement produces a higher durability concrete with lower permeability while maintaining constructability and reducing cost;' according to Shad M.
Nazareth, Pa.-based Essroc markets ground granulated blast furnace (
GGBF) slag cement under the i.tech Slag brand.
Process refinement led to PozzoStag 1.2, which imparts properties and performance similar to
GGBF slag and can be milled at volumes to ensure users consistent supply.
The Competition Commission (CC) has not identified any ready mixed concrete or aggregate market "problems," but provisionally finds a combination of structural and conduct features adversely affecting competition in portland cement and
GGBF slag.
