Strength And Durability Characteristics Of A 70% Ground Granulated Blast Furnace Slag (Ggbfs) Concrete Mix, David Newton Richardson
Strength And Durability Characteristics Of A 70% Ground Granulated Blast Furnace Slag (Ggbfs) Concrete Mix, David Newton Richardson

For a bridge pier and abutment mass concrete project, three mixes were studied: an ordinary portland cement (OPC) mix (Type I PC) and two 70% by weight ground granulated blast furnace slag (GGBFS) mixes (Type II Low Heat PC). One of the slag mixes contained a high range water reducer (HRWR). Tests for compressive strength, freezethaw durability, rapid chloride permeability, and salt scaling were conducted on field samples. Results showed that the strengths of the slag mixes were lower than the OPC mix at all ages up to one year, although the use of HRWR did improve the strength somewhat. …
